(The Great Escape 4, in a moment)

(Where is the last place for escapers in season 4?)

(The child care facility for the teenagers in need?)

(Where is everybody, then?)

(They found a clue there.)

(Do the kids feel constraint in the director's presence?)

(Something fishy is going on here.)

(At the very moment)

(They found a suspicious memo.)

(Something bad must've happened here.)

(They're getting closer and closer to the truth.)

(What will happen to the escapers?)

(Gimpo)

(Ho Dong shows up.)

How do I look?

You're wearing converse.

They match.

(He puts his hands in the pockets with confidence.)

- Hello. - Hi, Dong Hyun.

- Hello. - Hi, Byung Jae.

- Hello. - You're here.

(P.O is excited today.)

Last week,

Ho Dong and I were a team,

and Dong Hyun, P.O, Shindong and Jong Min...

were the action team.

I don't remember what we did. What did we do?

White Snake Society. The bag.

- The bag. - We had to deactivate it.

- The proverb. - The proverb.

You got the proverb at the end.

"Where there's smoke, there's fire".

I remember that.

That recalls your memory.

I remember that.

(When they were deactivating the last biochemical weapon...)

(When there's smoke, there's fire.)

(The miracle of one long proverb)

(They deactivated the last biochemical weapon successfully.)

(Dong Hyun showed what it means to be the Strong Father.)

Every time that happens, it feels like...

people who look like you take turns for each shoot.

It's driving me crazy too.

- Hello. - Hello.

- Jong Min. - Hello.

- Hello. - You dressed like fall.

Yes. You should take the lead in fashion.

- There's a breeze. - Right. I should take the lead.

It might be because...

I love Jong Min so much.

But no matter what he wears, he never looks like a celebrity.

- P.O looks like a celebrity. - He looks like a celebrity.

Regardless of what he wears.

(He's sad after hearing that.)

- Ho Dong. - You dressed up.

You look like you're just out in the neighbourhood.

You look like you were taking a walk.

- A man who's good at fights. - Jong Min.

The colour of your jeans.

(They criticize each other's fashion.)

This is the trend.

We were talking about the last shoot.

- Do you remember it? - What did we shoot last time?

I fell.

- That's right. - That's all I remember.

(Jong Min was in the lead as usual.)

(As a result)

(Jong Min.)

(This is how Jong Min remembers last week.)

(Jong Min. Are you okay?)

(Laughing)

(The end of the man who was in the lead)

- That was really loud. - Did you hear it?

- Did you hear that? - We only remember...

what happened to ourselves.

- We all only remember our bits. - Exactly.

Here comes Captain Shin!

- Hello! - Hello.

Our Golden Frog!

Seriously.

Frog, zombie.

- Come to the center. - Why?

- Come on. - Why? What's going on?

- We always... - It's your episode today.

- Really? - Yes.

When you go on YouTube,

almost 90 percent of our videos has Captain Shin in them.

So true.

- That's true. - The highlight reels.

It makes me so happy.

You search them all up?

I look them up all the time.

Honestly, you have "Star King",

"Strong Heart" and other shows...

- like "2 Days 1 Night"... - "Strong Heart"?

- You were in so many shows. - My old shows.

But this is the variety show I'm known for.

- What you're known for? - I guess you're right.

Don't you end up looking for your highlights?

Correct. I start by searching 'Shindong',

- I can't help it. - Do you read the comments?

All of them.

I even leave comments sometimes.

- Really? Wow. - Did you know?

When I turned into a zombie,

I wrote out a zombie cry instead.

- Really? - Yes.

- I felt like I had to. - Such method acting.

Yes.

This is what I'm known for, too.

(A bald-faced lie)

This is our last filming for this season.

- Yes. - Already?

All of our past seasons had the best episode...

- saved for the end. - Yes.

Season one was Taeyang Girls' High School.

(The escapers solved the secret of disappearing students.)

(They did their best.)

Season two was Murder Prison.

- Murder Prison! - Season two, right.

(Dong Hyun screams.)

(The scariest villain, Park Gang In.)

(The collaboration with Team "Problematic Men")

(Escape from a parallel universe! "Murder Prison")

Season three was Back to Gyeongseong.

Yes. Back to Gyeongseong.

- What is this? - This is huge!

(They came face-to-face with the city of Gyeongseong.)

(What will season 4's last episode be?)

What will this season's episode be?

I hope this episode,

the last episode of season four will leave no regrets.

- Okay! - Yes.

- The Great Escape! - The Great Escape!

- Good. - I love it.

- Move! - Move!

Let's go!

You're not talking about the sea today?

- What about the goblin? - Ocean, waves.

- Something doesn't feel right. - It was in the preview.

- So, I... - Can you just say it for us?

I'm going to leave you wanting.

- I want to hear it! - Me too.

Why won't you say it for us when we actually want to hear it?

If we're apart, we're all one drop, but if we're together...

- Let's go. - Move!

Leave no regrets.

Did you know?

There's an Escape Room World Championship.

- Really? - We have a national team.

- Wow. - I feel like Dong wants to try.

The team is 4 or 5 members.

- A team? - Yes. But what surprised me...

- Let's go. - This is a global competition?

- Yes. - It would be so fun to compete...

- against other countries. - Escape Room National Team.

Isn't it so cool?

We just need to speak a bit of English.

That seems to be the main obstacle.

(That's the only thing keeping them.)

Ho Dong's English skills are crazy.

(Artificial)

(Artificial Intelligent)

(Did you see?)

- Such a great quote. - Yes.

For a second, I thought,

a world championship with how many members?

If it's four, I'm on the fence.

Four people from this group?

- That's funny. - That means two of us can't go.

Dong and Byung Jae makes the cut, which leaves the four of us.

It's fierce.

It's the two in their best condition that day.

- The two in their best condition. - That's true.

- Whoever is lucky that day. - Seriously.

(I want to go.)

In this field, condition is everything.

- Yes. - The condition of the day,

- whoever leads in the beginning... - Yes.

- P.O did so well that day. - He did.

From the get-go.

I had actually let go some of the pressure that day.

(Did that help his performance?)

I ended up doing nothing.

- I just let go. - You fell down.

- I let go and... - You fell down.

- Isn't that a problem? - He let go and left.

Once you let go, there's no going back.

He went down.

Why are you all so down?

The last episode of the season.

Time went by so fast.

- Right? - It went by like that.

- It means we're getting old. - You get old so quickly.

Your memory goes as you grow older,

so every day feels faster.

I heard that too. Each day goes by like lightning.

- It's super fast for me too. - It's honestly scary.

Seriously.

That's why you can't remember things.

It's no joke.

- What are you mumbling about? - Just about his life.

- Everything's in vain. - I thought he was on the phone.

As I was listening, I realized I really did grow old,

because I can't remember anything you were talking about.

But it's just me.

This is serious.

- Yes. - Maybe I got hit too much?

I think that's why.

Your achievements are amazing.

If we were to talk about the highlights of UFC,

Dong Hyun is always included in the top 10 moments.

- This? - The elbow.

The elbow thing.

Wait. You remember?

I saw it about 1000 times.

You didn't have to see it that much!

It'll be vivid in my mind even when I'm 90 years old.

I will remember what the air felt like at that moment.

- He's amazing. - Honestly.

It's not easy to become a comedian after living as a fighter.

- When Dong Hyun first started... - Wait.

He's the first fighter-turned-comedian, right?

When Dong Hyun first started doing variety shows,

I thought it was a short outing.

I didn't think he'd be here for this long.

Right?

We didn't think he'd do a complete 180.

I didn't know either, honestly.

Everyone.

Please put your eye patches on.

Oh, we're getting close.

- Let's go. - Let's do this.

- This season's last escape. - Good luck!

I'll be more scrutinizing this time.

Let's try to look at the essence.

Yes. The essence.

(People's traces have been left...)

(all over this empty classroom.)

(But there's a dark secret hidden in this space!)

(Everyone here is in danger!)

(What will the escapers' fate be?)

- We're here. - Yes.

We have arrived.

I'll let you know the order you will exit the car.

Ho Dong. You're first.

- What is it? - I don't want to go first.

- This is my first time going first. - Strange.

- Is he going alone? - Am I going alone?

No. Jong Min, you're next.

Oh, it's oldest to youngest.

Dong Hyun, please exit the car.

- It's right. - I'm all the way inside, though.

(They're scared to have their name called.)

Then I should be next.

- Shindong, please exit the car. - I knew it.

You were right.

- Is it like the parking lot? - Byung Jae, please exit the car.

Last, P.O.

- Yes. - Ho Dong!

Yes? Who is it?

Where are you?

I'm over here.

- We're going. - We're moving!

What is this, asphalt?

Good luck, team!

- Good luck! - Let's do this!

- We're walking in. - Let's get through this.

(Let's get through this!)

- What is going on? - What is this?

Do we have to bend down?

- Bend down? - I don't think so.

- Dong Hyun leaned down. - We're walking in somewhere.

We're walking in!

We're inside.

- Wait. There's something here. - There's something next to me.

- I touched something. - It smells bad in here.

- Are we being locked in? - This smells like...

It's an empty space.

- Maybe storage? - Yes.

We're turning to the right!

(He's making a fuss.)

- Oh! - Jong Min.

Jong Min is...

- making a fuss. - Consistent to the end.

What is this?

- Where are we? - It got cooler!

It got cool!

I feel like we're outside.

- Isn't it the air conditioner? - The air conditioner?

(They're locked in.)

The door closed.

- Hello. - Hello.

I will be giving you a problem today.

Starting from P.O, it will go Byung Jae, Shindong,

Dong Hyun, Jong Min, ending at Ho Dong.

- You must say one letter each. - Dong, is this you?

In that order.

After the first person says a letter,

the next person must say the next letter within a second.

- A word. - I understand.

If you go over the time limit or say the wrong answer,

I'll move on to the next question.

- Yes. - Why does it have to be me?

Okay. I'll say the question now.

What is Socrates' famous quote,

in which he says...

realize your ignorance...

and discover a new truth from the ignorance?

And go.

You!

- You? - You?

- Kn. - ow.

- Thy. - Do.

Self.

- Dong? - You is correct,

but the answer is incorrect.

- Know thyself. - What was dong, then?

- Isn't it? - What was dong?

- What was dong? - P.O.

Did you say you in English on purpose?

- Yes. - Really?

- You shouldn't have. - You thought it was English?

But what about Jong Min?

- What was dong? - Why did you say that?

P.O, you're really good at English,

but you could've said it in Korean.

If you said it in Korean, I wouldn't have been confused.

Okay. Next question.

- Yes. - I didn't know.

- Why did you say that? - What?

I don't think you can get this wrong.

Yes.

This is the title of one of BTS's hit tracks.

It is also an item that Nobel,

the creator of the Nobel prize invented.

What is this item?

P.O. And go.

- Da. - E.

- Na. - Ma.

- E. - Teu!

Yes!

Let's take them off.

In 1, 2, 3.

(They take their eye patches off.)

- What is this? - Hold on.

Oh, my eyes.

Wait. The army?

For me, the Anonymous Request Box...

and letters...

remind me of the army.

So I thought, "Is this the army?"

(Counselling Room)

(It's like any other counselling room.)

(Newspaper clippings are on the board.)

- What I noticed first are... - What?

- the thumb tacks. They're strange. - What?

- There are so many. - It seems deliberate.

- I think it's a clue. - Yes.

Wait. This is a children's shelter.

Donations?

- What is this? - Haneul Shelter,

I'm still perusing it.

This seems to be called Haneul Shelter.

A shelter for children who need...

a warm hand and a roof over their heads.

That's what it seems like.

This person seems to be director Shin Ha Neul.

I didn't finish reading it,

but I think he's regarded as a very good person.

- He's doing a lot of good things. - Yes.

"The children are being chased out to the street."

"Will you lend a hand?"

Oh, like homeless children.

They take them in and care for them.

"Min Seo, who still resides in the shelter,"

"will become a high school student next year."

"Min Seo said, 'director Shin is like a father to me.'"

"'As he saved me, '"

"'I want to live helping others.'"

"She expressed her dreams of becoming a social worker."

I think this might be a clue too.

"Recently, Haneul Shelter's economic education..."

"through a mannequin factory has been drawing the public eye."

"Director Shin..."

"is trying his best to send the children back to their homes..."

"and school, but many are unable to."

"It's important to educate them economically,"

"so that they can stand on their own outside of the shelter."

"They receive wages by working at the factory..."

"and manage their finances on their own."

- It's fishy, isn't it? - A mannequin factory?

Something doesn't feel right.

- So he's using the children... - The children.

And exploiting them for labour.

Is he exploiting them for labour?

Or is he plotting something evil with these children?

Those were my first thoughts.

There are so many instances where they say they are...

doing good things, but it was all criminal activity.

So I thought, "There has to be something here."

(Mysterious Director Shin Ha Neul)

- But... - He has good intentions.

He's helping them to stand on their own two feet.

This door's locked from the outside,

- so we can't open it. - Wait.

- Why? - This...

allows you to see outside like this.

(You can see outside if you lift the box?)

What?

Maybe it's a hole to put something in.

(What's beyond this room?)

What's that? Is that the cafeteria?

(The cafeteria is completely empty.)

- Put your hand through and put... - Put in the passcode!

We can totally do that.

- This place... - We don't know the code.

(Discovery Kim puts his hand through first.)

- A passcode? - A number pad.

- Numbers. - It's the one you lift.

- You lift, input the numbers... - Oh, the lifting one.

- Like a keypad. - Exactly.

(Where would they find the passcode?)

(P.O finds something.)

What? What is it?

What is it?

- Did you find something? - It's nothing,

- but there's Braille here. - Braille?

The bookcase was filled with books about therapy,

but one book just happened to catch my eye.

It was a book about Braille,

which made me suspicious.

Maybe these thumb tacks are in Braille.

- Yes. - That's a possibility.

It is.

It's a high possibility that's the passcode.

What's that? What's with the candy?

(The music box is filled with candy.)

Candy.

It's scary.

It's broken!

- The mirror's broken. - Be careful.

- Byung Jae. - Yes.

The mirror inside the box is broken.

- Why is this broken? - I wonder.

We opened the music box...

and a wave of suspicion came over me.

The mirror was broken.

(The thumb tacks were strange from the beginning.)

- Is there anything similar? - These clippings,

- if they're here... - Wait.

- and suddenly, - What is that?

- Hold on. - Why?

(Did he find a clue in the Braille book?)

It's correct up to here.

- This, this, and this is right. - Why?

(The Braille P.O found.)

(He compared the thumb tacks to the letters one by one.)

(He found three letters that look similar!)

Dot, dot, dot, dot, dot.

- But this isn't there. - Exactly.

Then maybe it's just the first letter.

Yes. "Du" is right.

I can't really see Braille well.

This is kind of strange.

I think you're right, P.O.

(What are the thumb tacks spelling out?)

It has to be this, but something's off.

This is driving me nuts.

It's Braille. Hundred percent.

We have to leave the room by using Braille. Hundred percent.

We had to find the passcode that way,

but it wouldn't match up.

I was like, "what is this?"

These 6 spaces are 1 letter.

But it varies wildly on how you see them.

It doesn't match up.

This one's in an awkward place.

This one and this one too.

- Those three look strange. - Yes.

(If it weren't for these three thumb tacks, )

(the other ones do line up.)

- Or... - But why would this book be here?

- Look. - Why would this be here?

Look here. It says "number."

If I want to write out 500,

you have to write this first to specify it's a number.

The backward L.

Then people will know it's a number.

Doesn't this look like that?

The four thumb tacks?

- That's the number. - So, "this is a number."

- And then... - They write the number.

So these three have to be the number.

Six.

- And this one... - Four.

So it's 6, 4. Right?

- Yes. - Then all four dots.

So 6, 4, 7.

- Seven. - Two on the left.

- So it's 6, 4, 7, 2. - Six, four, seven, two.

The four digits.

That's the symbol for number, but I don't know what that is.

- Right? - Wait. 6, 4, 7, 2?

Should I press it? Just in case?

Would they have made it this hard?

- I'll press 6, 4, 7, 2 now. - Okay.

Where's six? I have to feel it out.

- On your side. - It's 1, 2, 3.

- Then 4, 5, 6. - Go the opposite way.

- Should I do it? - Yes.

(They change players.)

- Six, four, seven, two? - Yes.

- Press the digits, then push down. - Correct.

I got it.

(It's wrong.)

I don't even know if I pressed it correctly.

- I tried. - It's probably wrong.

Those thumb tacks have to be there for a reason.

- Exactly. - It has to be something.

(There are no unnecessary thumb tacks.)

What if you look at it like this?

(Like this?)

- It's still kind of off. - Yes.

Everything's a bit off.

Should I turn off the light?

- Sure. - What's that?

Oh. There isn't anything.

Can you see anything?

- No. - I don't think there is anything.

Turn it back on.

(Anonymous Requests Box)

This feels like our very first episode ever.

- Season one? - Locked in that room.

(When they were escape rookies, )

(they made tools, )

(they did what they were told not to do, )

(they broke things with brute force.)

(But they still couldn't leave the room for 2 hours.)

(They finally left the first room thanks to Door Jong Min.)

I think it's time.

Tap everywhere. See if it opens.

You have to doubt everything.

(He's doubtful.)

I think we have to solve the Braille.

(Byung Jae puts his hand through.)

I'm touching the outside right now,

but what if it has Braille on here?

I can touch it and see.

There are some rough places but I don't think it's right.

It just feels like paint.

Should we take out the mirror and see the keypad?

- See what it looks like? - Yes.

- That's a good idea. - Okay.

- How about this piece? - You can see with this.

Be careful.

- What about this one? - Here's the thing.

Hold on.

Isn't it meaningful to use this?

- It fits. - Put the whole music box through?

They want us to see it like this!

Can you get an angle?

- Perfectly! - Don't drop it.

- Like this. - Ho Dong.

It's so clear.

- Is it a keypad? - Counselling Room.

It's so clear!

Is it a keypad?

- I can see it. - Is it a keypad?

Is there Braille there?

It's so clear. This is what they wanted us to do.

The numbers are all there.

- No Braille? - It's the same?

There aren't any strange factors. It's a normal keypad.

(He moves it around.)

- I can't see well. You look. - I'll look.

Hold here.

- I got it. - You got it?

This way. Yes.

- The numbers... - What does it look like? Can I see?

Someone with good eyesight should see it.

(Byung Jae claims to have good eyesight.)

Oh, I got it. Guys.

It's this.

- There is Braille underneath. - What?

Wow.

(He found the Braille.)

- What? - Wow.

There was a mirror...

and there was a hole.

So we thought we had to see...

what we couldn't see before through it.

Ho Dong was looking with the mirror,

but he couldn't see it well.

So I tagged him and used the mirror.

That's when I saw the letters,

clear as day.

It was a thrilling moment.

We have to find the equivalent for them.

- Okay. - I'll look at it...

- and explain it. - Okay.

Oh, those are the numbers?

- It was under the keypad. - It wasn't this?

- It was there. - Byung Jae. I'm ready.

Say it like this.

I'll flip it and give you numbers.

- Okay. - Okay.

(He'll make the mirror switch and describe the Braille.)

I'll say them now.

It starts with the symbol for number,

- like Dong Hyun said. - Number symbol!

- Wow! - Nice!

(Dong Hyun found it first.)

(It starts with the symbol that has been flipped.)

Nicely done.

- Like this. - It starts with that.

It starts with the symbol.

- Okay. - Then 2, 3, 4.

- That's one number. - Okay. Next.

- Then 2, 3. - Two, three.

Then 1, 2, 3, 4.

Okay.

One, two, this is seven. I saw this one.

- Then it's 1, 2, 4. - One, two, four?

- That's it? - That's it.

- Okay! - Yes!

- Zero. - It is four digits.

It's 0, 9, 7, 4.

- It's 0974. - Zero, nine, seven, four?

We got it!

(Finally)

That's amazing.

(Byung Jae finishes the final step.)

(Unlocked)

Yes!

- Gather around. - It took one hour.

- This is a plot twist. - Did we get it right?

- This was really hard. - Is it over?

Look at that.

(Door opening)

- We were lucky we put this out. - That's right.

- Did you see what was outside? - No, since this was here...

and it was a little open, so I just...

- What was this? - Seriously.

This made it more confusing.

(The cause of confusion)

Let's take a look outside.

(Finally escaping the Counselling Room)

(Cafeteria)

It's the Cafeteria.

- There's no food? - What could this be?

- There's nothing to eat here. - It's the Cafeteria.

(Feeling uneasy)

It didn't look like a child care facility...

but more like a prison.

The kids ate here?

Is it supposed to be this shabby?

Look at the Dining Etiquette.

"Wait for your turn to be served."

"Take the food and sit quietly."

What's that?

I think this is the Cafeteria.

(It surely is a cafeteria, )

(but they're not getting any leads.)

The door here isn't locked.

Should we just go out?

I think so.

Every time we went into a new room, it was either closed or locked.

We usually had to think hard...

to solve the riddle and go out.

But when we went to the cafeteria,

the biggest door was open.

Is this...

supposed to be empty?

Could you open that for a second?

- This? - Yes.

What's out there?

- Dong. - What?

It's open.

(Classroom)

Is it a classroom?

(A learning place right next to the cafeteria)

It's scary.

(Silent)

I think you can just come here.

(Everyone is nervous...)

(at the unnerving atmosphere.)

- What's this place? - It's the Director's Office.

- The Director's Office. - It's the Director's Office.

(The Director's Office in the corner of the classroom)

The Confession Room.

(A mysterious room on the other side)

Confession Room?

Right behind the classroom was the Boiler Room,

then a Workroom.

Something seemed strange.

I found a bag.

(He found a bag.)

There's a bag here.

(A suspicious bag in the middle of the classroom)

A bag.

I think we need to look into that first.

- A bag here. - Let's look at that first.

I just saw this here.

What could be inside?

(Dong Hyun opens the lead.)

What could it contain?

(Opening carefully)

Look.

A speaker?

(After opening the bag, )

(they find a speaker inside.)

Something's written here.

"The batteries may last less than 60 minutes."

"Make sure to turn it off when not in use."

Is this an antenna?

- It's the antenna. - Can we listen to it?

I think we should turn it on.

Turn it on.

(The lights turn on after turning on the speaker.)

Sound.

Radio frequency.

Why doesn't it make any sound?

I found this too.

(He found another bag in the meantime.)

Wait.

"Incredible 24 Hours."

(Inside the bag...)

(is a familiar name.)

- What's that? - It's here.

(Even in Mirae University where the Black Tower was found)

(Even in Taeyang Girls' High School, the origin of Taeyangism)

It was from the show that explored about ghosts.

(Even in the Evil Spirit Prison where the ghosts were locked up)

("Incredible 24 Hours" was present in all incidents.)

"Incredible 24 Hours" was always...

present in Mirae University and other incidents.

An incident must've happened.

Something must've happened when they were exploring the issues here.

"Incredible 24 Hours" was from DTCU.

In my opinion,

there must be an incredible conspiracy here.

(What exactly happened here?)

(Looking through the producer's bag)

- There's a note. - I think it's his record.

There's something inside. What's that?

- There's something inside. - All right.

We'll read his daily records.

There's 94 percent of battery.

- "Please help." - What's that?

"Please help."

"The director is crazy."

(Please help. The director is crazy.)

I think this is a note that a person here...

left for the producer.

So a person here gave this note to the producer?

The producer must've come here thinking this was a good place.

(I can do anything for the kids.)

(Haneul Shelter donates 150 meal boxes for malnourished kids.)

(Please help. The director is crazy.)

(Who left this note?)

It's producer Yong Seung Nam's note from "Incredible 24 Hours".

"Sound Catcher was invented by Lee So Ri,"

"the guest of the show, 'Different People'."

"Interview is finished, but the schedule for the show is undefined."

"Sound Researcher Lee So Ri, 37 years old,"

"invented the Reminder Headset eight years ago."

"She became known as an odd person among inventors."

"She received bad reviews that her invention was evil."

"There are no machines left now."

"Sound Catcher is a new invention."

This must be the Sound Catcher.

"This machine catches residual sound waves..."

"within an area of 3 meters."

Residual sound waves?

- I see. - What is it?

It creates sounds from the past.

(Creating sounds from the past)

(Sound Catcher is not a normal speaker.)

We can hear sounds from the past?

We had a time machine...

and other equipment for escape until now.

But this was a first for me...

to see a speaker that can create sounds...

from the past, like this Sound Catcher.

"Only limited to the area the machine is located in."

We'll have to read further,

but if this works,

we can hear sounds that occurred from the past,

but only within 3 meters.

So if this moves here, it will make the sounds from here.

- I think so. - If it's here, we'll hear this way.

If this is in the Counselling Room, we'll hear what they said there.

- So everywhere we bring it? - We'll have to bring it everywhere.

If you look here, it doesn't show the radio frequency,

- but it says one day. - It's a day before.

It also shows 1 month or 3 months.

It means it can detect sounds from back then.

- You're right. - Right in this place.

- Right. - It depends on the date.

- It could be minus the days. - Or months.

- It says minus here. - That's right.

N refers to now.

This is an amazing machine.

I want to bring this home.

- What? - If we have this...

- I want this. - I think it's scary.

"Invention started in 2018."

"An exclusive interview was done by a Science Magazine."

"Battery issues were solved."

"Considering applying for permission for commercialization."

- This invention will help us... - Yes.

Hear sounds from the past. I think this is the key today.

(Sound Catcher could be the key to today's escape.)

When I say "Kim Dong Hyun," the sound waves...

will remain in the air,

which will be transmitted from this machine.

If there are unsolved crimes,

anything could be investigated using sounds.

"July 2, 2021."

"Reports by Kang Ba Ram's parents."

Their report says their child ran away from home.

"They found out their child was staying in Haneul Shelter."

"The parents visited Haneul Shelter a couple of times."

"However, they never got to meet their child even once."

That's wrong.

Due to the director's strong oppositions,

he was even against having a call with the child.

(The director refused to let them meet.)

It says the parents reported that their child,

Kang Ba Ram, had been missing.

There's Kang Ba Ram Shin Ji In on the chalkboard.

The news article is dated 2020, but this is quite recent.

- It's in 2021. - July 2, 2021.

(December 25, 2020 and July 2, 2021)

He was investigating on director Shin Ha Neul of Haneul Shelter.

He had been appointed as Professor of Chemistry in Hankook University.

He got fired in 2009 from his position...

due to a controversy in plagiarism.

Then, in order to get ordinated for a clergy position,

he went to the States to study abroad.

He established Haneul Shelter in Gilpo in 2019.

Then there were numerous articles about good works of Haneul Shelter.

It's what we read earlier.

There weren't any special remarks regarding outside activities,

so Producer Yong Seung Nam thought this needed investigation.

"First investigation visit on July 9, 2021."

"The children are too cheerful..."

"and they are extremely cautious of the director."

- That's strange. - It smells fishy.

Something's fishy.

"The indoor layout is complicated."

"An interview with director Shin. There wasn't anything special."

"I received a note."

- "This needs more investigation." - It was the note from earlier.

"Please help. The director is crazy."

"July 10 at 9 pm."

"An interview with a female student at Haneul Shelter."

"It was a phone interview."

"Scheduling another call at dawn."

He says the phone call didn't seem to be free.

"July 11 at 3am, second phone call."

It only says that without any details about the call.

"More investigation is needed."

August 20 is scheduled to be a follow-up investigation.

"Asking whether Sound Catcher is available for rent."

The Sound Catcher machine?

- He wanted to rent it. - That's what it says here.

He brought it to hear sounds from the past.

- Yes, to know what happened. - I think so too.

He wanted to hear what happened then.

- Wait. - There's a picture.

- This must be Kang Ba Ram. - Yes, I think it's Kang Ba Ram.

To summarize this,

I think Producer Yong took the hint that there's a problem here...

thanks to the mom's report.

The mom came here to see her child,

but she wasn't able to meet him.

She felt like there was a problem.

After reporting this,

Producer Yong came here...

and discovered that there was a problem here.

He's using the machine used for other investigation...

- to use it here. - In that case,

we might have to play it wherever we go.

- That's right. - Let's bring it everywhere we go.

- Shall we go to Counselling Room? - Also,

The batteries are not infinite, so shouldn't we conserve battery?

- Yes. - The battery...

- The battery has reduced already. - We have to hurry.

- Should we turn it off? - Yes. turn it off.

- The battery already decreased. - It's at 93 percent now.

Is that really the battery?

- Yes, we're right. - We turned it off.

We have to conserve the battery.

(The battery can be used for less than 60 minutes.)

What should we do now?

- Shall we start from here? - Let's start here.

- Or shall we look around more? - Should we take a look first?

- Let's take a look around first. - Let's look at the chalkboard.

- Shall we go to the chalkboard? - Yes, we should.

Did you turn this off?

- Yes, we did. - But wait.

Is no one coming here today? Is it meaningless now?

We don't nothing to be worried today?

- We don't know. - What if something just suddenly...

- Shin Ji In. - Kang Ba Ram and Shin Ji In.

Why are they learning such difficult things?

- What's that? Are those equations? - They're learning that already?

The multiplication formula.

XY.

Below are exponential equations.

There are sines and cosines too.

I learned all these when I was young.

(I learned it all when I was young.)

What's this?

- Where? - Trigonometric functions.

(They're all equal when it comes to Math.)

There's pi and roots and everything.

- 2 pi r. - So we have to solve this?

This isn't about solving.

- They just wrote the equations. - That's right.

(They move away from the chalkboard...)

(and start exploring the area.)

The Boiler Room.

There's a Boiler Room here and the Director's Office there.

There's another room here.

The Workroom.

There's even Confession Room here.

We need a lot of keys now.

- Keys? - Yes.

(Four doors they can enter)

(What secrets do these areas hold?)

If you look there,

I think those are the students' cabinets.

They have four-digit keys.

It consists of number keys.

- I think they contain a lead. - So those are cabinets.

We have to look through each one carefully.

- Why? - It's open.

- It can be opened? - It's 0000.

All of it?

Social Science book and Korean History book.

(Confused)

What should we do? Today's case is hard.

Are we...

supposed to find out what the director did wrong?

No, it's just...

that director Shin Ha Neul is fishy.

- You're right. - That's why.

I really don't understand people...

- who bully kids. - Director's Office needs password.

(Workroom)

(The Great Escape 4)

I really don't understand people...

- who bully kids. - Director's Office needs password.

Shall we go in the Counselling Room?

I don't know what we're supposed to do first.

Where should we go first?

- The Counselling Room. - No.

This one's locked too.

Today's case is really hard.

Shall we play this, Ho Dong?

- Yes. - Shall we listen to their class?

- I think we should start here. - Let's play it here first.

Yes, go ahead.

I think we have to test if this actually works.

Let's play it.

(Which sound and period should they look for?)

Since it's...

- August 22. - mid-August now...

Shouldn't we go back to three months ago?

(It can detect sounds up to three months ago.)

We just don't know if they did it here.

- We have to test if this works. - Sure.

- You think so? - Which period should we go to?

On July 10,

they had a phone call.

- In that case, - We don't know if they did it here.

If we adjust the radio frequency,

we might be able to hear any kind of sound.

- We find adjust the period. - Let's search for it.

We should keep looking if it's three days or a week ago.

Then, let's adjust it...

- to the past from the present now. - Yes, let's turn the time frame.

I'll turn it to the past slowly.

Sure.

(The story of the past told by the Sound Catcher)

(What happened here?)

That was startling.

Two days.

(D-2, Classroom)

That was startling.

Two days.

What?

(What is this sound?)

Based on the records on the producer's note,

the Sound Catcher is a machine that replays the residual sound waves...

that occurred in a particular area at a particular time.

So when we first heard it, it wasn't very accurate.

(Unclear sounds)

That's what I heard.

Play it again.

- Play it again. - Press replay.

(What was that sound?)

- Replay. - I think I heard "Get out."

How could you do that?

How dare you?

We can't keep doing this.

What about the other kids here?

Get out!

Go out!

Just leave already!

Go on!

I can't tell what they're saying.

(The sounds are still unclear.)

- They seem to be arguing. - Don't you think...

they sound a bit too far?

- Yes. - Like this was recorded far away.

- Shall we move this a little? - You're right.

- Where to? - The Director's Office.

No.

- Since they said, "Get out"... - If they were arguing,

do you think they were stopping someone from coming inside?

Is it from this side? Shall we move there?

To the door side.

(Moving to the door)

- We need to catch sound waves. - This is incredible.

Here?

- It sounded really far away. - I'll press Replay.

It sounds larger now.

How dare you come back here after saying that about us on TV?

You're saying you want an interview with the kids?

If you think it was wrong, you can come out on TV and explain yourself.

I'd like to know what the other kids think as well.

Know more about what?

Go out, mister!

Just get out!

You made a fool out of our director!

Go out!

Is that from the Director's Office?

"Come out and explain yourself."

- I think... - They're kicking out the producer.

- That's right. - That's what it seems.

But in their conversation, he said he came...

after finding out about a student.

Someone said, "You locked my kid up."

I think it was the producer who said, "If you think it's wrong,"

"then come out on TV and explain yourself."

But didn't the voice sound young?

I think it was the students.

It wasn't only director Shin who stopped the producer,

but we heard voices of the students...

trying to stop him.

- Shall we hear it again? - "You manipulated us, mister."

- Let's move closer. - Closer to the Director's Office?

- Or to the door? - Shall we go closer to the office?

Should we stand in between here?

- Was it this side? - How about this side?

This side.

- Let's go to the Director's Office. - Maybe closer to the door.

Here?

We won't be able to hear it if we're too close.

- Try it here. - I'll play it here.

- I'll play it here. - This is two days ago.

Replay.

How dare you come back here after saying that about us on TV?

You want an interview with the kids?

If you think it was wrong, you can come out on TV and explain yourself.

I'd like to know what the other kids think as well.

Know more about what?

Go out, mister!

You made a fool out of our director!

Let go of me!

Okay, I think they're just fighting.

Because this machine...

does not record the sounds,

but detects residual sound waves,

I think we'll have to move around to look for the sounds.

Anyway, he came two days ago to ask questions,

- but he got kicked out. - They sound like they were arguing.

Since this was two days ago, shall we see if there's more before?

It sounds clearly here near the Director's Office.

It must've been somewhere near here.

I'll turn it further to the past.

Maybe it sounds more clearly near the Director's Office.

I think so.

(When is that?)

I...

A week.

What?

A week ago.

With the lies that people won't believe,

- It's unclear. - Let's move again.

You disgraced me.

(It sounds like someone's mad.)

Raise your hands straight!

(Where did this happen?)

Does week mean it happened a week ago?

- Yes. - This was a week ago.

- So a week ago from today? - Yes.

I can't hear anything.

(Is it over?)

We have to listen to it again. Was this a week ago?

This is what they said a week ago.

- One week. - "You disgraced me."

I heard something about disgrace.

That must be over there...

- on the stand. - The Boiler Room?

- No, on the teacher's stand. - In front.

- In front of the teacher. - The stand?

- "You disgraced me." - Someone was getting scolded.

Would it be the Counselling Room?

Let's first go this side.

- Workroom? - "You disgraced me."

When they have classes here?

- Here. - Yes.

The most merciful Haneul...

who created the earth.

The most merciful Haneul...

who created the earth.

We give glory to you...

for guiding us to live as your creation.

Thank you for sending us the kind messenger Father...

- and guiding us... - Are they praying?

To ascension.

Use your sinful creation...

according to...

your plan.

Do not hand the poor sinners...

to the hands of the evil,

and may they ascend...

to where you are.

Amen.

Amen?

- This is a week ago. - They were praying here.

- Yes, a week ago. - They were praying here.

This is from class.

Director Shin Ha Neul...

went to study religious studies in the United States...

to get ordinated.

- So this is a mission school? - He could have got something there.

- So religion-related... - Hold on.

But what we heard from there...

- is different from this. - It's different.

Maybe they were talking on the sofa?

So the conversation happened here...

- a week ago. - Yes.

And on that side, they talked about being a disgrace.

- So it happened inside. - We should go to the cafeteria.

Shall we hear it again? Replay it?

Could you hear what they were praying?

Something about guiding them to ascension.

We'll hear it again.

(D-7 Learning Hall Follow-up interview)

Who on earth...

is talking about our shelter to the outside people?

With lies that even children won't believe,

you disgraced me.

Hold your hands up straight!

Who is it?

Who did the interview?

Who did what?

Interview. "Who did the interview?"

"Who did the interview?"

They're getting scolded for doing the interview.

- There's more. - No one?

(Director Shin Ha Neul)

It looks like...

some people have been led astray by the faithless...

and have started to doubt Haneul and Father.

Who and Father?

Let's recite the prayer.

The most merciful Haneul who created the earth.

The most merciful Haneul...

who created the earth.

We give glory to you...

for guiding us to live as your creation.

Thank you for sending us...

the kind messenger Father...

and guiding us...

to ascension.

Use...

your sinful creation...

according to...

your plan.

Do not hand the poor sinners...

to the hands of the evil,

and may they ascend...

to where you are.

Amen.

So he's forcing them to do this.

At first, Director Shin Ha Neul...

yells at them asking who did the interview.

But no one answers.

So he tells them to recite the prayer.

I don't know much about religion, but they're praying to Haneul.

But his name is Ha Neul.

They pray to Haneul,

but the Director's name is Shin Ha Neul.

So they're worshipping him?

- He made himself divine? - Yes.

His name is Shin Ha Neul?

Earlier,

before praying he said something.

He said someone is doubting him.

Asking who did the interview.

- "Who disgraced me!" - He said they lost faith.

So they were led astray by faithless people.

- It's like a false religion. - Yes.

I really don't like such things.

False religion and child abuse.

- Right. - It's the worst.

Shall we listen to an earlier point in time?

Or shall we check other places?

I'll set the frequency again.

I'll go to a further past.

Should we listen from other places too?

Do you hear something?

I went to the end. I guess there's no more.

There's no more here.

It's 75 percent now. It was 92 percent earlier.

That's quick.

Shall we go to the Confession Room?

- Let's go to the Confession Room. - Okay.

But would it work to hear it from in front of the room?

Should we enter it...

- when it opens later? - Right. That's true.

In that case,

- The Counselling Room? - the Counselling Room is better.

The Counselling Room?

- Shall we go there? - I think it's better.

I'm curious about that place too.

- Let's go there first. - We should find the key then.

- We should find the key. - But,

All the keys would be in the Director's Office.

I think we'll get to hear a hint for the Director's Office.

- The passcode? - Yes, the passcode.

- Like from the sound of it. - I see.

Let's start from here. If the volume is low here,

it would be outside then.

It's cool here.

We could hear the interview from here too.

I'll start with now.

One week.

One month.

(D-44, Counselling Room Follow-up interview about punishment)

- One and a half months. - One and a half?

Our Haneul Shelter...

prioritizes the children's financial independence.

We're not just helping them.

The children work at a mannequin factory...

and earn their own money.

We help them get independent...

by allowing them to manage that money.

- That doesn't sound bad. - They might have been...

underprivileged teenagers when they came to the shelter,

but when they leave,

they'll become a full member of the society.

That makes me feel satisfied.

You are an amazing person indeed.

But,

someone reported to us a piece of information.

Well,

does this child stay here at the shelter?

(The picture of Kang Ba Ram they got earlier)

Yes, that's right.

Oh.

The informant was the mother of this child.

She called the shelter to meet her child...

and also requested to visit the shelter.

But she said the shelter didn't allow her to meet the child.

It's kidnapping.

- Producer. - Yes.

I'm providing warm beds and education...

free of charge...

to children who have nowhere to go.

Children mostly run away from home...

because of domestic violence.

So it's against the aim of the shelter...

to send the children back home just because the parents want them.

That also makes sense.

- Of course, - He talks well.

The children wouldn't want that too.

I see.

Right?

- This is all I have to say. - Yes?

You've come all the way here.

Why don't we have a meal together?

The food at our cafeteria is great.

- I still have some questions. - Now, let's go.

I'll lead you to the cafeteria.

- Come with me. - Okay.

- Let's go to the cafeteria. - It's the cafeteria.

Is it done?

- Yes. - Okay.

It was the interview. This one.

No, not this interview.

This is from July 9 by Producer Yong Seung Nam.

He interviewed the director but found nothing special.

I think he got the note on this day.

- From Kang Ba Ram. - Kang Ba Ram.

He knew that it was Kang Ba Ram,

but he asked everyone who it was.

No, he doesn't know the informant yet.

- They don't know that. - They don't?

So there would be someone who did the interview later.

- Right. - A staff or an insider.

We'll know who gave the note at the cafeteria.

Shall we go to the cafeteria? They would have eaten there.

So who gave the note?

So anyway, it's Kang Ba Ram...

- We're looking for the informant. - But it was the mother.

- Yes. - It was the mother.

It's possible.

It's possible it's Kang Ba Ram.

Because that was a week ago and this was a month and a half ago.

That's right.

(Someone had an interview earlier.)

(D-7, Punishment because of interview)

(D-44, First interview)

(What happened at the shelter during the month?)

It's one and a half months ago, just on another location.

Yes, just next door. They had a meal.

But there's nothing. I think there should be something.

Hold on.

One month...

- It's the same. - The same day.

(D-44, Cafeteria)

(The escapers focus on the sound catcher.)

(But they can't hear well.)

Anyone talking?

(They couldn't find any clue.)

- What? - There were no talking sounds.

Let's replay it and move around just in case.

I think that's a good idea.

Yes, they might...

just be eating from here.

- Somewhere here. - I pressed replay.

Come here.

And here.

(Would they be able to hear something else?)

At first, the sounds were very soft.

If we're here, what happens from there...

cannot be heard well.

So if we go there, we'll be able to hear it louder.

Then we'll be able to know where it happened.

So we just walked around with it.

We should find it.

Did they just sit and eat?

It's possible that they didn't eat.

Can you hear anything?

I hear it.

- You're done eating, right? - It's from here.

Go and give her my business card.

- It's getting louder. - Don't let others know.

Yes, sir.

(A business card of Producer Yong Seung Nam?)

(They can only hear the sounds from eating.)

They said something in the beginning.

- They were whispering. - Yes.

- Shall we listen to it again? - Yes, because...

there was a bit of talking in the beginning...

and then I could hear something like paper.

So I think this is when he got the note.

- Let's play it again here. - Okay.

- Replay. - Yes.

Hey.

I got a note from that girl earlier.

(Producer Yong Seung Nam)

I was giving out rice...

and she gave me this.

Awesome.

(Assistant Director)

You're done eating, right?

(Producer Yong Seung Nam)

Go and give her my business card.

(Producer Yong Seung Nam)

Don't let others know.

(Producer Yong Seung Nam)

Yes, sir.

(Assistant Director)

(D-44, Cafeteria, Exchanged note with a business card)

There are two reporters, right?

- I think so. - They're with the camera crew.

Yes, I think the two came along.

The production crew members are saying...

that one was helping with giving out rice, when one girl...

- The girl who gave the note. - Yes.

And it was a girl.

They gave her the business card...

and later did the interview.

That's how they got the interview.

There's a record from July 10.

One student in Haneul Shelter.

In brackets, a female student.

They had a phone interview, but she couldn't talk freely.

So they'll call again early morning.

They made the call in the early morning, but details are not here.

The details of the call.

If it's a month and a half ago, it's about the same period.

- Yes. - Right.

We can hear the details of the call with this too.

That's possible, but we don't know where the call took place.

- We don't know where it was. - We don't know.

Also, it's likely that they don't have phones in their rooms.

In that case, it could be...

the Confession Room or the Director's Office.

- Boiler Room. - Yes.

Somewhere that has a phone.

Would they have allowed individuals to carry...

their own phones?

- They wouldn't have. - Or it could be hidden.

(Where did the interview take place?)

(Confession Room)

(Director's Office)

Shall we listen to an earlier date?

Let's listen to it and go to the Director's Office.

Let's check out if there's an earlier date.

(They check if there are more sounds left.)

Minus 3M.

It went to the end.

- There's none at the cafeteria. - There's no more here.

We're running out of battery.

Let's go to the Director's Office and check.

- The clues are getting clearer. - Yes.

Could we perhaps hear it in front of the Director's Office...

to check the passcode?

- The sound of the numbers? - Yes.

- The numbers each sound different. - Yes.

Or we could be lucky and hear the Director...

press the numbers while saying it out loud.

Saying, "the passcode is..."

- We could hear the sound. - Some people can tell.

Shall we?

Shall we hear the sound?

Should I press the numbers?

They're all the same.

- It's the same. - Are they all the same?

It all sounds the same.

- It should be different. - The old phones had it.

- Let's hear the sounds. - Okay.

Put it up here.

You can be doing this...

and why don't we go check if there are clues in the interview?

Can we not charge it?

The Interview Room?

People normally set their passcodes...

with something related to their personal information.

So the interview of Director Shin Ha Neul.

- Like dates? - Yes. Like birthdays.

- Let's go and check. - Okay.

Just in case. We'll go and check.

Okay.

We have to divide the work.

(Efficient division of roles)

We can check for dates.

I'm not trying to emphasize P-Ho Dong or something.

It was smart.

The Director must have a number that he likes.

Perhaps that number could be hinted here.

(What information would be on the interview?)

We should check.

- There was no Christmas. - What?

(Meanwhile)

(Captain Shin is searching with the tuner.)

- You're going through it? - Yes.

There's nothing.

- Nothing? - It's not there.

There's nothing here.

How about in front of the Confession Room?

- In front of the Confession Room. - Shall we try there too?

- Okay. - I'll take the chair.

Okay.

After this, we should find out the passcode of the Director's Office.

Okay.

Now, the Confession Room.

It's 3m by 3m here.

- We can try it here. - Yes. It fits.

Somewhere here.

Now we'll go from the start.

This is difficult.

There's none.

It's not here.

(Nothing comes out of the sound catcher.)

The battery runs out too quickly. It's already on 50 percent.

Fifty-eight. We've already used half.

(The battery level dropped to 58 percent.)

Where should we go to find the passcode?

Like Ho Dong said,

The Boiler Room. Have we tried there?

(The only place they haven't tried the sound catcher.)

- In front of there. - Yes, in front of the Boiler Room.

Shall we go to the Boiler Room?

I'll carry it.

- Kids may talk in the Boiler Room. - It's possible.

I wonder who is in charge of the Boiler Room.

(Would the sound catcher work?)

I'll try it now.

From the beginning.

There's nothing.

It's not there.

- Nothing? - Nothing.

- Nothing. - Or we could...

try the Director's Office.

Did you find anything?

Well,

the only dates there were May 5 and December 25.

- And... - Just those?

And something on...

(They found no special dates.)

the year 2019.

Director.

Director's passcode. Director's birthday.

- When was this place founded? - On March.

- March? - Yes.

- It's March? - If it's March,

- March 15 was the interview date. - Yes.

(They found the founding date of the shelter on the article.)

(Monday, March 16, 2020, Haneul Shelter opened in March 2019)

Perhaps the interview was to commemorate the first anniversary.

Would it be?

In that case, the passcode would be 0315.

(The interview would have taken place on the 15th.)

- Or... - Do we have many chances?

Zero, three, one, five.

(Could it be?)

(Wrong)

Zero, three, one, four?

(Two days before the article was written, 0314.)

- Zero, three, one, four. - Why?

You have to press the Asterisk.

It's wrong.

(The date when the article was written, 0316.)

This is wrong.

What do we do?

What happened?

He pressed too many times.

- The passcode could be here. - There?

There were some things that couldn't be erased.

(Come to think of it, )

(they found a suspicious board in the Nurse's Office in Season 1.)

(The numbers that don't get erased?)

(They got the numbers after erasing the board.)

(They found the passcode by Dong Hyun's idea.)

(Perhaps this time too...?)

There were some things that couldn't be erased.

- But, - Shall we erase it a bit later?

- We should be careful. - Right.

Just in case.

(They wouldn't be able to restore it once erased.)

We have to be careful.

(We shouldn't make rash decisions.)

- We don't know. - We erase it all and...

Let's try until we can.

It was a nice approach,

but I thought if we erase it,

we won't be able to turn it back.

So I said it would be better to try it...

if we don't find anything else after trying some more.

(Byung Jae heads to the Director's Office again.)

Byung Jae is going.

- No, I'm just checking. - What?

I don't know. I'm just going to check.

How do we open the Director's Office?

We'd need to open it to find something.

(Byung Jae checks the office alone.)

It looked like...

the Director's Office would be the key area.

Because...

I could see a cordless phone in the office...

through the blinds.

I thought the call would have been made through that.

Ho Dong, as you said earlier,

the call interview could have taken place here.

There's a cordless phone here.

Right.

- It wouldn't be her phone. - They wouldn't allow that.

(The sound catcher remains silent.)

(Time passes by.)

Why is there no clue?

(Everyone wanders around.)

(And Byung Jae heads back to the board.)

I found it!

I found it!

I found it! I found the Braille!

(There's something behind the chalkboard?)

- What is it? - The Braille.

Where?

- We found it. - What is this?

We found it.

(There's a Braille text on the back of the chalkboard.)

(There's a Braille text made with thumb tacks.)

This is amazing.

You found it there?

I was just checking if there was anything on the back.

Then I found the thumb tacks.

- Goodness. - I checked the board too,

but only the front side.

The Braille book.

(Here comes the Braille book.)

This is amazing. We keep finding Braille texts.

(Does it refer to the passcode to the Director's Office?)

We might as well just carry the book with us.

P.O, could you translate it?

Translate it.

- This is the number chart. - Number chart.

There are 4 of 2 rows.

The first one looks like an L.

- Eight. - Eight.

Two on the top.

- Three. - Three.

The 1st one and the 4th one.

- Five. - Five.

- Five. - Eight, three, five.

The last one looks like an L but upside down and reversed.

- Six. - Eight, three, five, six.

- Eight, three, five, six. - Eight, three, five, six.

- Eight, three, five, six. - All right.

- This is amazing. - The kids put it here secretly.

- Behind the director's back. - Nice.

Nice.

(The students made the Braille in secret.)

Once we get inside, we'll be able to get a lot of clues.

Eight, three, five, six.

- Eight, three, five, six. - Eight, three, five, six.

- Close it. - Press the star.

- It worked. - It worked.

Byung Jae.

- Nice. - Awesome.

Byung Jae, well done.

- Very nice. - Let's go.

It's hot in here.

(The place gives off somewhat strange vibe.)

(Director's Office)

Is this where the interview took place?

- Yes. - This is the place.

(It's the sign they saw from the article in the Counselling Room.)

Once we turn this on, we'll know what happened.

- I think so too. - Shall we take a listen?

Let's turn it on.

- Shall we listen to it? - Let me put it in the middle.

- Please turn it on. - Get ready to write it down.

- I'll turn it on. - Okay.

Turn it on.

(Focused)

(What clue is the rest of the sound waves...)

(in the Director's Office hiding?)

- I hear nothing. - Oh.

- I hear nothing. - Oh.

When was it?

- When? - "M 1.5"?

That means a month and a half ago.

Someone is opening the door.

The person came in.

Someone came in.

(The door's closed.)

(They hear a mysterious rattling sound.)

(It's a sound of pressing something.)

The person is using the computer.

(They hear some clicking sound.)

It's the phone.

The phone.

(Is the sound from the buttons of the phone?)

Are you the producer?

I gave you the note yesterday. Remember?

Of course. I was waiting for your call.

I have something to tell you about the director of this shelter.

Okay. Please go on.

I think this place is...

not just a teen shelter.

I think it's more like...

a cult group.

They make us chant...

some strange prayer every night.

And I think the kids here are becoming weirder.

They've definitely changed.

They seem possessed by something.

Hello?

Hello?

I don't think I can talk now.

Can I call you at night?

Okay. I'll be waiting.

I'll come down to the office later at night...

and call you again.

I'm sorry.

Her bedroom must be upstairs.

(They hear some rattling sound again.)

(Girl's phone interview)

(It looks like she left the office before someone finds her.)

Thank goodness. She wasn't caught.

(Even after she left, there are some sound waves left.)

(The door opens again?)

- What was the sound in the end? - Who was that?

- Didn't it sound like a man? - Some person with slippers on.

- I also heard some breathing. - Heavy breathing.

It sounded like the person was using a cane.

- Did it? A cane? - The person could be limping.

- That must be it. A cane. - I could picture someone limping.

The girl? Is it the girl?

That's what I thought.

She's suspecting she might be in a cult group.

She said they're asked to chant some strange prayer...

and the kids here are getting weird.

She said they seem possessed by something.

And I think the kids here are becoming weirder.

They've definitely changed.

The producer also wrote...

that the kids here seemed anxious around the director...

and seemed too cheerful.

Could this be because of the possession?

It might be. Possession?

(Meanwhile, Captain Shin is searching the office.)

(On the table, there are miscellaneous articles...)

(and a group photo.)

This must be the girl.

(One kid catches Captain Shin's eyes.)

How do you know?

She has a cane.

Oh, you're right.

- This girl? - Hey.

There's a kid with a cane.

She seems blind.

So she doesn't have a leg problem.

She's blind.

- That's why she used Braille texts. - That's why.

(That's the reason why there were Braille texts everywhere.)

("Braille Self-study for Visually Impaired and Beginners")

Is Ba Ram here too then?

Ba Ram must be here too.

Could he be Ba Ram?

- He looks like Ba Ram. - Here.

(P.O keeps searching the room.)

It's a music box.

(He finds a music box.)

(It's the same one as the one they found in Counselling Room.)

Candies.

Why does he like candies so much?

(All the music boxes are filled with candies.)

(They open the drawer underneath.)

Are there more candies?

(The drawer is filled with candies too.)

(Maybe this is not a clue.)

(The monitor doesn't turn on.)

(And the phone...)

- Ho Dong. - Yes?

The interview must have been done with this phone.

Maybe there's a call history left.

You're right.

- What is it? - It says, 010...

- Right? - and 476-7859.

There was a call with this number.

It's Producer Yong's number.

When was the phone call made?

- A month and a half ago? - Yes. A month and a half ago.

- A month and a half ago. - A month and a half ago.

What?

There must be more.

- What was it? - Wasn't there some crackling sound?

- There was. - Dial it slowly.

What's this...

- Wait. - Stop there.

Stop dialling when you hear some sound.

It's from four days ago.

Eun Mi Ri.

Cheon Soo Ho.

How dare you...

How could you do this to someone who take care of you?

How dare you say something like that to the outsiders?

- To the outsiders? - I did it.

Mi Ri didn't do anything.

That's not true, Father.

- She calls him Father. - Soo Ho didn't do anything wrong.

It was all my fault. I did it.

I need to teach you a lesson.

(That sound is...)

(A music box?)

They're eating candies.

(Why are they eating candies?)

(Rattling)

Follow me to the Boiler Room.

The Boiler Room?

The Boiler Room? Let's listen to it again.

- Let's listen to it one more time. - Yes.

Eun Mi Ri.

Cheon Soo Ho.

I need to teach you a lesson.

(Soo Ho and Mi Ri are in trouble for the interview.)

(Then the melody plays.)

Why did he suddenly play it while scolding them?

The candy.

Maybe there's something in the candy.

The key to the Boiler Room was in here.

(The key to the Boiler Room...)

(is in the music box?)

(Thumbs up quietly)

Then he tells them to follow him to the Boiler Room.

Oh, Ho Dong.

I need to teach you a lesson.

(He moves the candies.)

- That's right. - There's a key.

- That's right. - There's a key.

The key...

is in there.

Next week.

(The truth of the shelter is shocking.)

(There is no trace of human.)

(What happened in here?)

(Then they suddenly hear a mysterious sound.)

(A dead body appears before the escapers.)

(Who killed them?)

(Then they find a clue that overturns all their deductions.)

(There is another dark secret.)

(An enormous conspiracy reveals.)

(Get rid of children?)

(Their evil deeds go beyond your imagination.)

(There is not much time left.)

(They must escape in a rush.)

(Do not let your guard down to the end.)

(Will they be able to escape successfully?)
