Jae-suk!

-Jae-suk! -Jae-suk!

Remember that there's always an exit.

E, X, I, T are capitalized.

-E, X, I, T. -Jae-suk!

-Jae-suk! -Where's Jae-suk?

Jae-suk was still inside.

What is this place?

Hello?

What is this place?

What?

What's this?

Where am I?

What is going on? Where am I?

What is this?

Why am I chained up?

I can only go this far.

I need a key.

Where is my cell phone?

What is this?

What is this?

This is the deepest place on Earth

and the hell of the Gods, Tartarus.

This is the deepest place on Earth

and the hell of the Gods,

Tartarus.

Who is this person?

Because you have sinned countless times,

you will be judged in this hell.

I hate insects!

You have always betrayed your colleagues' trust.

You've never failed to betray someone.

I'll be loyal to you!

He's a typical traitor.

-I'm disappointed. -Master.

Like Sisyphus,

whose punishment was to spend eternity rolling a boulder up a hill,

you will also have to work hard.

Sisyphus?

Sisyphus?

Even a glimpse of a cow in a field reminded you of beef.

You were always full of desire to eat.

Look! Cows!

Their meat must taste great.

They do look tasty.

You are like Tantalus, a man with an eternal punishment

of insatiable hunger.

I will give you the chance to eat as much as you want.

You will have to eat the feast I prepared for you

in perfect order without leaving anything behind.

Why is that something I should be punished for?

Danaus, Sehun.

You have a competitive streak that is unrivaled.

The way you obsessed over winning a toy from the claw crane

was quite memorable.

What is he doing back here?

How do you think you'll feel when you become a claw crane?

Enjoy the game to your heart's content.

Am I in this situation

because I won a toy from a claw crane that one time?

Your name is Echo.

Do you remember the green tea farm in Jeju Island last year?

You screamed and backed off, making your colleagues do all the work.

This time, things won't go your way.

I prepared charming friends for you so that you wouldn't be lonely.

Good luck.

Ixion, Jong-min.

You got to where you are with your luck.

You let your colleagues do the grunt work

and left everything up to your luck.

Will your good luck help you

-when you are under the fiery wheel? -I got to where I am with my luck?

Jeez. What is this?

What is that? "Ixion.

Cassandra incurred the god's wrath.

Don't ever trust her..."

Who is Cassandra?

What does that mean? Who is Cassandra?

Who is Cassandra? Why shouldn't I trust her?

You are Cassandra.

You are always in the middle of everything

and oversee and orchestrate all matters.

"Cassandra incurred the god's wrath."

"If you trust her, you will face a bigger calamity."

"Don't ever trust her..."

"Only trust yourself and act."

You are Cassandra.

You are always in the middle of everything

and oversee and orchestrate all matters.

Your colleagues need your help right now.

But whether you can save your colleagues remains to be seen.

Remember this. Being a true team means

that every member is connected.

Well then, good luck.

You don't sound sincere at all.

Pandora's box?

What is this? I need numbers for this lock.

What was that?

My goodness.

My goodness!

Jae-suk.

Why is Jae-suk hanging up there?

My goodness.

Last year...

Hey! The door won't open!

Try opening it from the outside!

Was he alive all along?

Everyone is locked up.

Jae-wook is there.

Why is he above the water?

Se-jeong is there. Everyone is...

Your colleagues need your help right now.

Why is this turning?

What is this?

What is this? What...

This is...

What is this?

Blue?

These are the colors of the monitors.

What was that?

That felt cool.

My goodness, I don't want to go.

The colors...

I think the color of the microphones match the monitors.

Gosh.

I think I can help free them

by using those microphones.

I need to save them as soon as possible.

What am I supposed to do?

Wait, I need to find a key.

The key's over there.

How am I supposed to get it?

There are Roman numerals.

What is going on? For goodness' sake!

How do you think you'll feel when you become a claw machine?

Enjoy the game to your heart's content.

What? Why is it moving on its own?

What's going on? Is someone operating this?

Gosh, it's cold. For goodness' sake.

How does the machine operate?

Do I need to speak to it? One.

K.

Danaus. Sehun. Forward.

What? Gosh, stop.

Oh, so this is how you operate this machine.

Left.

Stop.

Okay, I know how it works now. Do I need to untie those knots?

Blue, yellow, and purple. The ropes are connected.

"Echo." As in the reverberating sound?

This moves.

It can go all the way up.

What is this?

What are those?

For goodness' sake.

What's in number two?

For goodness' sake.

I prepared charming friends for you so that you wouldn't be lonely.

Good luck.

Goodness.

Gosh, what am I supposed to do?

What the...

What was that?

It fell to the center.

I think it needs to be balanced.

Hold on. Do I need to put those creatures in these containers

to balance the scale?

That means...

I won't be able to get out.

Let's see.

One, two, three, four... Oh, I need to roll them up.

I need to roll these balls up.

For goodness' sake! Jeez!

Hey!

"Gaia"?

Gaia.

I need to place the one with the same name.

Mercury. What? There is no Mercury.

Shall I roll these up?

Like Sisyphus,

whose punishment was to spend eternity rolling a boulder up a hill,

you will also have to work hard

to match the weight of trust.

What is this?

Come on!

Is water flowing out?

Why is the water coming out?

"Grilled scallop with carbonara sauce.

Porcini mushroom soup."

I like the menu, but...

This must be grilled scallop with carbonara sauce.

It looks delicious.

My goodness.

I hope you have the manners to use the appropriate cutlery.

Let's see.

You will have to eat the feast I prepared for you

in perfect order without leaving anything behind.

That way, you will be able to find the key to escape.

It's so good.

But...

What is going on?

Is this made of drinkable water?

My goodness.

Why are you doing this to me?

Should I stop eating?

Gosh, hurry up.

Come on, untighten.

I will try one person at a time.

Do I need to eat everything?

Se-jeong, can you hear me?

-Se-jeong, can you hear me? -Who are you?

-It's me, Min-young. I can see you. -Goodness.

Min-young!

What are you doing? Why are you eating?

Do you know the solution?

No, I don't. Min-young, it has been a while!

I know. It's good to see you again.

But Jae-suk is tied up somewhere.

I think he will be killed soon with a bow or a gun or something.

-What? -Which means you need to

complete the mission soon. Do you know how?

Gosh.

I need to complete the mission soon? Okay, I will eat quickly.

The water is coming out again.

Why is the water coming out?

This is driving me crazy.

Why is it moving on its own?

Should I stop eating?

All right.

What?

What is going on?

Why?

Why?

What is going on?

-Kwang-soo, can you hear me? -What?

It's me, Min-young. I can see you through a monitor.

Kwang-soo, you need to put the planet models in place, right?

Is that Min-young's voice?

Aren't those planet models?

-Min-young! -Kwang-soo.

-Min-young! -Yes?

Are you talking to me?

Yes, I am. Hurry up and put the planet models in their places.

-Min-young, have you been well? -Yes, Kwang-soo. Have you been well?

-Where are you? -Long time, no see.

-I can't talk long. -Can you see me?

Min-young, don't go.

Min-young, don't go.

What is going on? What is it?

Hold on. I didn't write anything yet.

I didn't write anything yet.

Hold on. I haven't yet...

Jong-min, can you hear me?

-What? -Jong-min, it's me, Min-young.

-Jae-suk is hanging somewhere. -Min-young!

I did nothing wrong, but this chair keeps going up.

I didn't touch anything.

If I don't get out, I think I will die.

-You think you solved it? -No. I think I will die.

-You think you solved it? -No. I...

Goodness.

So far, I have...

Min-young?

Min-young?

Nine, one, one.

Is that one a cobra? Why is it lifting its head?

This is so annoying.

For goodness' sake!

Jae-wook needs to touch the snakes.

Sehun's mission is... Does he need to tie them up?

What is she taking out of the freezer?

Soapy water keeps coming out.

Why is soapy water coming out?

I did nothing wrong, but this chair keeps going up.

I didn't touch anything.

Did someone make a wrong move?

What makes Jong-min's chair go up?

Your colleagues need your help right now.

Remember this. Being a true team means

that every member is connected.

There is a chain of events.

The rooms are connected.

When Jae-wook screams at the snakes,

the meter goes up.

Does that make Sehun get dropped into the water?

Every time Sehun makes a mistake, the stoves ignite in Se-jeong's room.

Every time she takes out a spoon,

soapy water comes out in Kwang-soo's room.

Every time Kwang-soo's planet model falls,

Jong-min's chair goes up.

When Jong-min makes the wrong phone call,

a steel ball falls into the scale.

Everyone needs to do well in order to escape.

-Jae-wook. -Hey!

Be careful not to shout from now on.

If the hand goes over to the red section, Sehun suffers.

When do the stoves ignite?

Tantalus. Cassandra.

-Se-jeong. -Min-young.

Every time you open the freezer,

Kwang-soo gets showered.

So, be mindful of that.

Kwang-soo, whenever a planet model falls back in,

it makes it harder for Jong-min to solve the problems.

The point is, all the rooms are connected.

All the rooms are connected?

Jong-min's room... Darn it.

-Darn it. -"Darn it"?

Min-young.

Min-young! Why did you say, "Darn it"?

How old are you?

Does Sehun's mission involve

tying the ropes?

I untied the ropes. Why isn't anything happening?

Mission accomplished.

Give me the key.

Danaus. Give me the key.

Cassandra.

Give me the key. I give up.

I give up.

Okay, it's either one or three.

It's either one or three.

GA x NA, DA x RA, MA + BA = ?

So three. Three is...

Okay. Ra is one.

I am doing a good job. One.

Eight. Eight, nine. It's eight in the middle.

Ga is eight.

This is nine.

Four. One.

Na is one.

One. This is two.

No, wait. The numbers don't add up.

These aren't one and two. This one must be eight.

Eight.

Ga is two.

Hold on.

Hold on. Ga is... This is driving me crazy.

Gosh. Oh, gosh.

Then ma must be one. Ma is one.

No, wait.

No, hold on.

I am getting goosebumps.

I just need to find what da is.

Five, six.

Seven, eight. It's nine.

All right. Now...

Two times one is two.

Then da times ra is... Five times one is five.

Then ba plus ma is...

Ten. The answer is ten.

GA x NA, DA x RA, MA + BA = ?

This goes here.

All right.

"Jupiter."

The key. It's here.

Let's go.

Be careful not to open the freezer.

So try not to change the cutlery as much.

Gosh, what is this?

What is this?

I found it!

-Jong-min. -Hey, Min-young.

Since Kwang-soo completed his mission,

your chair won't go any higher. You can solve your problems in peace.

-Really? -Yes.

Can you see the second problem?

-The second problem? -Yes, there are three dice.

I think it's asking for what's on the opposite face of each dice.

-The opposite face? -Yes.

The opposite of one, three, and four on the dice.

What are on the opposite sides?

Oh, I see. You are right.

The opposite of one on a dice is...

-Six? -Yes, six.

The opposite of three is four and the opposite of four is three.

When I add them together...

Thirteen?

Use that with the problem you solved earlier.

Yes. Oh, I see.

I get it now.

Min-young, I get it now.

What is it?

I thought arithmetic operations were missing in between.

But they're not separate numbers.

I was supposed to combine na and da to make one number.

Did you get it?

No wonder it didn't make sense.

So, 330 plus 9 equals...

The answer is 339.

One, three.

Three, three, nine, one, three, nine.

That's not it.

I did get where I am with pure luck.

I'm sorry.

Why do the ropes on the left and right have the same colors?

Do I need to tie the ropes of the same colors?

Gosh.

I don't want to say, "Start."

Start.

Forward.

Stop. Here.

What is this? I can't reach it.

Go up.

Left.

Stop.

This is the last one.

I'm finished.

What is going on? No, stop.

Stop.

What's that?

Nice.

I completed the mission.

What is this building?

"D-3629"?

"D-3629"?

What is this place?

-What? -Who is there?

Sehun!

-My goodness. -Jae-wook, hello.

Sehun!

I thought I was here alone.

-Look at that. -Gosh.

Sehun can grab them for him, then.

Two rooms remain.

Jae-wook, since Sehun is in your room,

he should move the larvae and the snakes to the scale.

-What do I need to do? -Do you call that wisdom?

-What? -Anyone can say that. It's obvious.

It's still wisdom.

Sehun should do it.

I can't do it.

You need to hurry up.

I wish I could do it for you,

but I can't go because I am chained up.

It seems like we need to go and save her.

-I don't want to do it. -Me neither.

I can't go because I am tied up.

Just bite the bullet and grab them.

My head hurts.

How do I solve this?

I solved the first part, but...

The dice is...

-Jong-min. -What are you doing here?

Gosh, what is that?

-What is that? -Hey. Don't go!

-What is that? -Kwang-soo, save me!

You idiot!

Kwang-soo!

I'm going to kill that jerk when I get out.

-What should we do? -Hurry up and do it.

We need to get out of here.

They won't think this is a weapon, will they?

Climb onto it. Climb up.

Gosh, I am sorry.

-You are doing it, right? -I'm not hitting it.

I'm trying to get closer to them.

Come here.

Okay. There you go.

I will carry you. Stay still.

Stay still.

Stay still.

Stay still. Don't do anything.

I will put you down slowly.

Be careful. There you go.

-What is it? -What?

-Anyone here? -Let go!

-Sehun. -Se-jeong, please hold this.

-Se-jeong, please hold this. -What are you doing?

What is that?

What is it?

What is that?

Look at that!

Gross!

Bye.

There are a lot of big snakes.

If it weren't for you, I would have left already.

What do you mean, Sehun?

Should I go in?

-How should I do it? -I will protect you.

-What? -I've got your back.

All right. Let me move you a bit.

I am sorry. Let me move you a bit. I am sorry.

I am sorry. You are startled, right?

I am sorry. I'm really sorry!

I'm sorry!

It didn't move.

I am sorry. Don't be startled.

You are so pretty!

-How pretty. -Don't be startled.

-You are so pretty. -I am sorry.

No, don't move!

Larvae are disgusting.

Larvae are so disgusting.

I am sorry. I won't startle you.

I will put you here. I am sorry.

-There you go. -How many snakes do we need to add?

Seriously.

-Se-jeong. -I am sorry!

-It's okay. Don't stop. -Sorry!

-I am sorry. -Go slowly.

Don't be startled. Did I scare you?

I am sorry. Don't be scared.

I am sorry.

Don't flick your tongue. I am sorry.

Don't flick your tongue. Go inside.

I am sorry.

What are you so sorry about?

What's the reason?

-For touching them? -They must be startled.

-Jong-min. -Hey.

-Wait until I get my hands on you! -Have you been well?

Come on. Solve the problem with me.

-What are the problems? -I am almost done.

-What are the problems? -Kwang-soo.

Min-young.

Kwang-soo, help Jong-min.

You need to get a phone number.

-We shouldn't trust her. -You need to get a phone number.

-We shouldn't, right? -Look behind.

She is Cassandra. We shouldn't trust her.

DON'T TRUST CASSANDRA

You are Cassandra, aren't you?

I am, but that doesn't have anything to do with this.

So hurry up and solve the problems.

Don't trust her. Let's solve the problems by ourselves.

Don't be absurd. Just solve the problems.

Oh, she can hear everything.

You should whisper.

She will get cut off soon. We should talk then.

Okay. I am almost done.

For goodness' sake. Why won't you believe me?

They need to solve the problems quickly.

I just need to solve the third problem.

-It's a layout of a dice. -Yes.

What numbers go in ga, na, da, and ra?

GA + NA + DA + RA = ?

-The opposite side of one would be six. -Yes.

I know that much.

Isn't it two plus three plus four plus five?

Isn't the answer 14?

Fourteen? Hold on.

From the other problems, I have three, three, nine, one, and three.

One, three,

one, four.

What's that?

What is going on?

Be careful!

What is going on? Be careful!

-My goodness. -What is going on?

What the...

-What is going on? -What is going on?

What's going on?

Fire!

-What's going on? -No, don't come!

-What is this? -What is going on?

-What is that? -It's a key.

Kwang-soo.

-That was intense. -I was so scared.

They completed the mission.

-You idiot! -It's not like that.

It's not like that. I simply visited another room.

-That was hard. -It's worse in the other room.

I am sorry. You must be scared.

I am sorry. Please excuse me.

The container is filled with snakes, but...

I know. We are nowhere near reaching equilibrium.

-Did you complete the mission? -No, not yet.

It's impossible.

-Se-jeong. -Gosh, she must be crazy.

-It will bite! -Se-jeong, don't do it.

Se-jeong moved all those snakes.

-That one is coming out! -Come on.

-Se-jeong! Hey! -I am sorry.

-I am sorry. Don't be startled. -That one is coming out.

-My goodness. -It worked!

-My goodness. -It worked!

It worked. It really did.

-It's balanced. -It is.

-Hurry up. -Come on!

-We did it! -Come out!

It fell.

There you go.

I see that you haven't changed a bit.

What do you mean?

-None of you have changed. -I moved one snake.

-Is that worth bragging about? -I did move one snake!

I've changed.

-Where is Min-young? -Min-young!

-Cassandra. -I'm in here!

-Where are you? This room? -I'm here.

-It's this room. -It's this room.

-But... -I'm in here.

-Hold on. -It won't open.

-We need to use all our keys. -The keys.

Do we need to save Cassandra?

-The message said not to trust her. -That's right.

Trusting her will bring a calamity.

IF YOU TRUST HER, YOU WILL FACE A BIGGER CALAMITY

-Cassandra. -Kwang-soo.

-Yes? -I will never help you again.

-I guess I didn't earn enough trust. -I am sorry.

Min-young, you said "Darn it" to me so many times.

-We will insert the keys. -Hold on. We need to figure out

-which key goes where. -The Roman numerals.

I saw some Roman numerals

in my room.

-In your room? -Yes.

-Really? -There were Roman numerals.

The first one was red.

Do you mean the colors of the ropes?

Red, blue, green, yellow, and purple.

Red, blue, green, yellow, and purple.

It opened!

It opened!

-What? -Red, blue, green, yellow, and purple.

-It has been a while. -Look at the monitor.

There is Jae-suk.

-What? -Where?

-He is over there. -Is that Jae-suk?

-My goodness, that's a crossbow. -What is going on?

-It really is him. -My goodness.

The explosion must have been a distraction to kidnap him.

I know.

We don't even know

-where Jae-suk is tied up. -Yes.

Open this first.

-How? -Where's the key?

It must be inside this.

I need four numbers.

There must be a key inside this box.

We don't know the password.

Any four numbers come to your mind?

Maybe "Cassandra" is the hint.

What is Cassandra?

Perhaps the numbers are hidden in this mural.

Sehun's room had a clue

about the sequence of colors.

Did other rooms have numbers?

-Jong-min. -Yes?

Did you get any four-digit numbers?

-Your mission was related to numbers. -That's right.

-I didn't get four numbers. -What about the dice?

There were no four digits.

What was the phone number?

It was 339-1314.

Let's try 1314.

So, 1314...

-We did it. We opened it. -What?

-What? -How?

The last four digits of the number.

-Really? -Yes.

-It's 1314? -It worked.

-It... -What's this?

-What is that? -D-4207?

It's a building number.

-Does each building have a number? -Yes.

I saw it outside before I came in.

"D-3629"?

-What was the number? -D-4207.

What?

-Will Jae-suk be there? -Yes.

There are signs.

-D-4207. -D-4207.

D-4207.

Jae-suk must be waiting for us.

Jae-suk.

Jae-suk! Where is he?

What is this place?

Where are we?

-It's this building. -It's on our right.

This is it. D-4207.

-We're here. -It's an examining room.

It is? This is...

-What? -There he is.

-It's Jae-suk. -Gosh, that startled me.

It's Jae-suk.

-It's Jae-suk. -Gosh, that startled me.

-What? -What was that?

-It hit his stomach. -What?

-Jae-suk. -Did it hit him?

-Jae-suk. -It really hit him.

-Go get him. -Is he dead?

Turn the crossbow away.

-It isn't real. -It's not.

-It's not Jae-suk? -It's a mannequin.

-Is it a mannequin? -It's a mannequin in his outfit.

-It's a fake. -It's a dummy.

The outfit is Jae-suk's.

How did the crossbow get fired?

-We didn't fire it. -How did it happen?

What is this?

-The trigger was connected to this rope. -It was.

The weight moved down

and pulled the trigger automatically.

Someone set this up.

-That person ran away. -So it would get...

But who would set it up?

Judging from the fact that an arrow was fired,

this person knew we would come here.

-It hit his stomach. -I can't get it out.

-What's this? -There is a message.

-What? -It says, "Find us."

If Jae-suk got caught up in the explosion,

this outfit wouldn't be

-in one piece. -You are right.

-Thus, -It would have burned.

-Jae-suk avoided the explosion. -Really?

He must have found something and ran before the explosion.

Otherwise, Jae-suk's outfit wouldn't be in one piece.

-It would have been burnt. -Does that mean he is naked right now?

That's right.

That's why we need to save him. He must be embarrassed.

That's a sight I don't want to see.

I thought he passed away.

-Don't say that in such a carefree way. -It's not like that.

We worked on many cases with him.

It was a big explosion.

You said that as if he is some stranger.

The paint is fresh.

-What's that? -What?

There are keys!

"File," and "Boss."

-Boss and File? -Yes.

"D-11."

This must be the key for it.

That must be the location of the file.

-Take off the plates. -Be careful.

-Are there two? -Is something written on it?

-There is something behind it. -What?

Is it a microchip?

I think they're numbers.

Some numbers might show up if we do something.

Like a license plate number?

"H."

-An English alphabet? -What is this?

Maybe you have to scratch it.

"Boss."

-"File." -"File."

Could this be the answer?

-B, O, S, S. -B, O, S, S.

-D-11... -F, I, L, E.

What do you mean?

Wait. Boss?

Eight, zero...

Eight, zero, three, three?

Why does Boss become eight, zero, three, three?

B, O, S, S could be

-eight, zero, -Eight, zero.

-five, five. -That's right. Eight, zero, five, five.

-Right? -I think so too.

-You are right. -Am I right?

It's eight, zero, five, five.

Then what is this black part?

It should be "File."

What if this gets added to the "F"?

-Then it becomes three. -What is this?

"F" is number three.

One. "I" becomes one.

-The letters are flipped. -"L" becomes seven.

-When you turn it upside down? -"L" becomes...

"E" becomes three.

-You're right. -What's right?

-Am I right? -You're right.

-Right? -Three.

-You're right. Then... -I see.

So the boss is at 8055.

-The boss. -The file key

-is for 3... -At 3713.

-We will go to 8055. -Okay.

-Se-jeong. -I'll go to the boss too.

-File. -We should've

paid attention to the building numbers on our way here.

-Be careful. -Let's hurry up.

-Be careful. -Let's go.

-There is a sign. -There is a sign for 3713.

-There's a building. -Look.

Let's go this way.

We're going into the mountains.

-This way. -We should turn right.

There it is.

-It's 5508. -What?

We said the number is 8055, right?

Maybe we need to flip that one as well.

-Five. -It's this way.

Isn't this it?

There it is. D-3713.

It is.

What did you do to break your camera?

-Did it break? -Yes.

-Where is he? -Gosh, this place is scary.

Enter.

There's a door here.

It looks like we don't need to unlock this door.

-Is this the entrance? -It's so dark inside.

Kwang-soo, I'll go in first.

-Min-young, we will go in first. -Min-young.

-Min-young. -Min-young, be careful.

The room numbers here start with a D.

-Was it 11 that we saw earlier? -Yes.

-It was D-11. -Yes.

-It must be a room number. -This place is so scary.

-Min-young. -Yes?

We shouldn't split up.

-Us? -Yes.

Here are the rooms.

-D-08. -Watch your head.

It's room D-11.

-Room D-11? -Yes.

-It's for this room. -There's a key here.

-What is this? The door is open. -Really?

-Is there anything inside? -No.

There are gloves.

Hold on. Where is Kwang-soo?

I don't know. Where did he go?

Kwang-soo.

Kwang-soo.

-Kwang-soo. -Kwang-soo.

Where did he suddenly go?

Kwang-soo.

We're here.

-Building 5508. -It's this building.

Why are the windows broken?

-Oh, gosh. -What?

-My goodness. -That startled me.

Who are you? Oh, gosh.

That mask is scary looking.

Is it just the three of you?

It's Jae-suk!

-Yes, it's me. -Jae-suk!

-Jae-suk! -You were alive!

-It's me. -What are you doing?

What are you doing?

Have you been well?

-Hold on. -It's been a year.

Why does your mouth look the same without the mask?

I can't believe you!

Se-jeong, what are you talking about?

My mouth doesn't look the same without the mask.

This is a surprise.

Well, if I have to tell you, it's kind of a long story.

I watched you through the monitors.

You couldn't move a single snake with your hands.

-Seriously. -You wouldn't have been able to do it.

That's why I prepared the snakes for you.

-You watched us through the monitors? -Yes, I've been watching all along.

Did you orchestrate this?

As you know, we solved various cases

ever since K hired us.

-Lee Ki-woo! -We have to catch him!

Then, a year ago,

I was in a room when a bomb blew up.

-A shipping container blew up. -That's right.

Hey, the door won't open!

I found an emergency exit on the floor.

I escaped through that exit.

Remember that there's always an exit.

More importantly,

while everyone was outside before I entered the container,

K had given me a note.

Don't tell the other detectives.

Trust no one.

Is that why you didn't contact us for a year?

That's why I couldn't contact you for a year.

I am sure you didn't know,

but over the past year,

I watched each and every one of you to determine

who I should be suspicious of.

That's why I talked with K

and set up some difficult situations

to test you one last time.

-You tested us? -Yes.

-You did? -Yes.

-You tested us? -I did it with K.

-Oh, with K? -Yes.

Who is at the other building? K?

That's right. K and the rest of the detectives will come here.

They should be here. Some time has passed.

They should be here any minute.

-There they are. -They're here.

-Min-young! -Who is that? Jae-suk!

Min-young.

-Move out of my way. -My goodness.

-Move out of my way. -I am disappointed in you.

-Have you been well? -Jae-suk, you are alive!

You are wearing a different outfit.

-Hold on. -Where is Kwang-soo?

-Where is K? -K? What K?

Didn't you go to find a file?

-Yes. -There was no file.

It was stolen.

What? Where is Kwang-soo?

Kwang-soo stole it.

-What? -What?

-Kwang-soo. -Kwang-soo, stop joking around.

Kwang-soo, stop joking around.

You can joke around, but you can't take the key.

Kwang-soo, stop joking around.

Kwang-soo.

-Kwang-soo. -Kwang-soo.

STORAGE

Min-young, there is something here.

Kwang-soo opened this and left.

-Kwang-soo did? -Yes. This is our key, right?

-Here. -That's right.

-But Kwang-soo... -So, the three of you were together,

-but he disappeared? -You should've kept an eye on him.

The two of them swiped it.

-What are you talking about? -I mean...

-I mean... -With K?

The microchip is expensive, right?

There was a man who wanted to sell it. What was his name?

-With the glasses. -You know,

-Se-jeong. -Yes?

You became tougher in a year. I like it.

It's a scary world out there when you don't have any work.

You are right about that.

Let's not waste our time and just call K.

-Do you have his number? -Of course.

You should have called him right away.

The person you have called is unavailable right now.

It says K is not available.

This is strange.

-Why did K turn off his phone? -Could someone have kidnapped him?

-Then we-- -The worst-case scenario is that

Kwang-soo could have

-done something... -To K?

Let's go check the place where K might be.

K and I made plans

at his vacation home yesterday.

Let's go there. We need to find out if our plan has gone awry.

We won't know for sure whether or not Lee Kwang-soo ran away with

the microchip until we go to K's vacation home.

K was supposed to be there with the microchip, right?

Of course.

Hold on. I received a text.

-You received a text? -Yes.

-From whom? -Lee Kwang-soo.

-What? -What?

"I have the microchip. I did this for a reason.

Please trust me. I will go back."

-What is this? -What is this?

D-11. I need the key.

D-10.

It's in the order of 9, 10, and 11.

Okay.

There is nothing here.

STORAGE

Kwang-soo.

Kwang-soo.

Kwang-soo.

Lee Kwang-soo, that punk.

Wait a second. What is this?

-What? -Why is the police here?

-My goodness. -What is going on?

-What is going on? -What is going on?

-Did something happen? -What happened?

We know the owner of the house.

We need to see him today for an important matter.

Sorry, you can't go in.

-We need to find something. -We won't take long. It's...

-We need to... -What is this fuss about?

What?

Are you challenging my authority?

Hold on. It's not like that.

This is the house

-of someone we know. -Who are you? Are you a detective?

I am the detective who is in charge of this case.

-What is going on? We... -Hold on.

Aren't you my former colleague who joined the force in the same year?

Isn't it you, Detective Ahn?

-That's him. -That's him.

I heard you left the force

to become a private detective.

-If you are Detective Ahn's friend... -Hold on.

-Let's go inside and talk. -No. Nothing comes that easy in life.

-Wait. -Stay behind the line.

-We know the owner. -Move back.

-Move back? -Move back.

Are you challenging my authority? Move back.

We didn't do anything, okay?

You talk too much.

-Sir. -Yes?

I know the owner of this house.

Let's go inside.

Hold on.

May we go inside and check something?

Nothing in life is free.

What do you want us to do?

It's time to make a decision.

What is up with him? He is a strange detective.

-Se-jeong. -Yes?

-Show him how cute you are. -Show him.

Sweetie, let us in the house. Pretty please?

-Goodness, look at her. -Se-jeong.

-Come on. -Se-jeong, what are you doing?

Please stop. Please go back to where you were.

-Detective Im. -I'm doing many things today.

Detective, what happened to the man who lives here?

It looks like he doesn't know.

Today, a bloody and gruesome murder

took place in this house.

-What? -What?

There is a body in this house.

But the owner of the house had plans with me.

I hope that person wasn't the victim, Detective Ahn.

We found the body of a man in this house.

-A man? -There's a body in the house?

It could either be K or Kwang-soo.

Anyway, a murder took place in this house.

You are nearly done with the investigation, right?

-Hold on, Detective Im. -Can we go in?

Hold on. Wait.

There he comes. He is a colleague of mine, Sergeant Kim Min-jae.

Okay.

I am Sergeant Kim Min-jae. It's nice to meet you.

It's just that we know the owner of this house.

If it's okay with you, we would like to check the crime scene.

without ruining evidence.

If you happen to know the man inside the house,

please cooperate with our investigation.

We will do that. You don't need to worry.

We will keep the crime scene as it is. You don't need to worry.

Please assist them.

-Let's go inside. -We will go inside.

-I must take this phone call. -Please wait.

-May we go in? -Yes.

Don't touch evidence at the scene without my permission.

Of course not.

K!

-K! -Is it K?

-It's K! -But...

Do you know this man?

We know him.

How did this happen to K?

You said you met him yesterday.

I was supposed to meet him today as well.

K was with him.

Make sure to prepare everything for tomorrow.

Have the keys and the file ready.

Yes, sir.

When did he pass away?

The estimated time of death is between 11 p.m. and 1 a.m.

-Between 11 p.m. and 1 a.m.? -Yes.

That means he passed away after I left.

He must have been attacked in his sleep

-after meeting up with Jae-suk. -That's right.

Was he found today?

Here is what we have so far.

The victim is a 55-year-old man named Ahn Nae-sang.

Seems to have been killed in his sleep.

The crime was reported by Ms. Choi,

the caretaker of the vacation home who is in her 60s.

Currently, she isn't in the list of suspects.

Why is she not a suspect?

Her alibi checks out and no evidence points to her.

That's why she isn't in the list of suspects.

Did you keep the sunflower and the knife

-as they were found? -Yes, they were found like that.

-Why a sunflower? -What...

-Sunflower... -Well...

We don't know anything for sure yet,

but I believe this is the doing of The Flower Killer.

-The Flower Killer? -Come on.

-Oh, my goodness. -Jeez.

Sergeant Kim, you are jumping to a conclusion.

-It's not The Flower Killer. -He startled me.

When The Flower Killer strikes,

he never uses a sharp weapon or leaves behind any wounds or blood.

Thus, this wasn't done by The Flower Killer.

Sergeant Kim, you always make hasty judgments.

-Take it slowly. -This is

Lieutenant Yoon Jong-hoon, who is a crime scene investigator.

-Lieutenant Yoon. -Who are you?

Who is The Flower Killer?

Could you please tell us who that is?

The Flower Killer is a notorious serial killer.

What?

He is an intelligent criminal

who doesn't leave any fingerprints or evidence behind.

Because of that, the police are still struggling to catch him.

-A serial killer? -Yes.

Does he always

leave a flower at the crime scene?

Yes. He always leaves a flower behind.

Who are they and why are you giving them information?

We are detectives.

What makes you certain it wasn't The Flower Killer?

-Oh, it's a pleasure to meet you. -Nice to meet you.

I am Yoon Jong-hoon, and I'm the mascot of the Crime Scene Investigation.

It's a pleasure to meet you.

If you have any questions, please ask.

-She did. -What was your question?

What makes you certain it wasn't The Flower Killer?

As you can see, the most obvious clue lies

on the solar plexus.

Solar what?

The pit of the stomach.

-You could have said it in simpler terms. -I'm a professional, so...

The knife wound

is neither clean nor sharp.

-What? -It's rough.

-Is it rough? -It wasn't done by an expert.

-It wasn't? -No.

That's why you said it wasn't a serial killer.

-Yes. -Maybe it's a first offense.

Why did the killer leave a flower? It's strange.

And what are all these numbers?

We numbered the evidence.

-We did this. -This is standard procedure

-by the police. -Isn't that obvious?

Please give us some time.

We will take a look around without damaging

-the evidence. -Okay.

-You have ten minutes, no more. -Okay.

There is something here.

-What is this? -Is it a microchip?

-Is it a barcode? -A barcode?

Isn't it a QR code?

Sehun, scan the QR code.

What happened to K?

What is going on?

-It pointed us to something. -Really? Let me see.

-What? -It's K.

-Are you crazy? -That startled me.

Do you want to blow this up?

We need to get rid of him.

He even stole an important test subject.

You better make the right decision

before it's too late.

-Who is the speaker? -Who is he?

-Who is he? -You can hear a ringtone.

-Let's watch it again. -Who is the tied up man?

-Are you crazy? -C?

-C? -The reflection in the mirror.

-Do you want to blow this up? -Isn't that C?

Are you crazy?

I gathered opposing forces and began researching.

Get him.

-It's C. -C.

-It's him. -It's C, right?

It's C.

Are K and C on the same side?

Yes. Wait, are they?

-But C... -C is a bad person.

-The two of them -That's right.

are laying the blame

on this man in the middle.

Wasn't that man in glasses a researcher or something?

-That's right. -That girl's dad.

-The dad. -The dad.

-The dead girl. -He's

-the dad of the girl who went missing. -He's her dad.

I think it's him.

K told me that

if something bad ever happens to him,

I should find Tartarus.

If something bad happens to me,

find Tartarus on the second floor.

Yes, sir.

Let's go to the second floor.

What was it? Hell?

Tartarus.

-This is where... -Yes?

I spoke to K yesterday.

-What is this? -Is this a laboratory?

PROJECT D

-There are clocks. -"Tartarus"?

-You are right. -It reads "Tartarus."

What is this?

-I don't know. -Earlier,

one side of Kwang-soo's backpack was broken.

Right, the camera on his right side was missing.

What did you do to break your camera?

-Did it break? -Yes.

It's really broken.

Does that mean he was here?

That means he was here before he met up with us.

Could Kwang-soo be the murderer?

What?

-No way. -It has no batteries. It won't turn on.

Jae-suk, Kwang-soo's floor plan is the only one missing.

-What? -His floor plan.

There are floor plans for each room

and an explanation on how to complete each mission.

-That's right. -He must have stolen it ahead of time.

Kwang-soo must have broken his camera

-while he was running away. -That's right.

But K told me to find Tartarus.

Maybe the time could be a clue.

I think they are pointing to a location.

These clocks aren't working.

That's why I think these are the hints.

Why is Tartarus divided into parts?

-This is... -My head hurts.

We are detectives.

We should be able to solve something like this.

-I know. -Right?

It's been a year, so my brain is a little rusty.

Thirteen.

-What could it be? -The answer must be lying here.

Would you think that to yourself?

Gosh, what could this mean?

I wrote down the number

-Yes. -each letter in the alphabet goes with.

There are two hands. One each for the hour and the minute.

There are two letters as well.

T is 12 and A is 18.

R is 11.

-T is... -It's 37.

So T is 12.

-But... -I am almost there.

Don't lie.

Don't lie.

-Seriously. -There's no way.

I was thinking hard! For goodness' sake.

You won't solve this even if you stay here for a year.

The Genius Detective Team from a year ago would have solved this right away, right?

Right?

They would have solved this

-in no time. -They were good.

I know the young member of that team.

-What? -We became close.

Those clocks could be pointing us

-to the next location. -It must be a location, right?

Maybe they simply represent a four-number password.

If we move the hands to a certain time...

Can we move the hands?

-Jong-min. -Yes?

Jae-suk, don't touch the clocks.

Wait, let me try something.

-Let me try something here. -Go ahead.

-Just once, okay? -No one here is going to stop you.

I have no idea.

What was the time on the first clock?

Min-young, only you can solve this.

-Why did you move it that way? -Next.

-Let's see if it works. -It was 7:26.

-Let me give it a try. -Okay.

-Why did you set it to this time? -Let me try it first.

If it works, I will explain.

-What time did you... -I set it to 20:01.

It opened.

-What? -It worked.

-You are a genius. -Min-young.

-You are a genius. -No, I'm not.

-That was incredible. -There is something inside.

-How did you solve this? -Seriously.

There are two hands for the hour and the minute.

I thought there must be a reason why a word got divided into two letters each.

From A to Z, I assigned numbers to letters.

Since T is the 20th letter of the alphabet,

I thought of TA as 20:01,

RT as 18:20,

and AR as 1:18.

-That's right. -Goodness.

-So this one -She is a genius.

would be 21:19.

-Seriously. -She solved it faster than me.

-No matter how much... -I was close to solving it.

-We don't need the Genius Detective Team. -We don't need them.

This is what we got.

There are drawings of a star,

a house, and a rainbow?

Something like a castle, and...

-A wheel? -What could this be?

-Why is the star circled? -I know, right?

Isn't this... Isn't this used for stargazing?

-Hold on. -There is a house, too.

Hold on.

-It looks similar. -That must be it.

Wait, that's...

-Right? -That must be it.

-Right? -Yes.

-Right? -That's the place. You are right.

Star. Telescope.

-Use it to look at the house. -Look at the house.

So we use this telescope to look at the house?

Come on.

-Hold on. -"Look at the house?"

Look at the house.

So we look at the house.

-Look at the house, Sehun. -That's right.

-Look at the house first. -That's right.

-I know that much. -Stop it.

-There's nothing shaped like a donut. -Stop it, you.

-There is nothing for this drawing. -What could it be?

-Do you see that Arboretum Resort? -Yes.

-I think it's supposed to be that. -Right.

I think this drawing of a house does represent the roof of that building.

-And the one next to it... -What is the next one?

When we look at that house with a telescope...

When we do that...

What is this?

I am certain that's the place.

But the shape looks more like that one.

Then we should go there.

-Be quiet. -You suggested something similar.

That's not a good idea.

The first two drawings lead us to that building.

Once we go there, we might see the rest.

-That's right. -The third drawing.

That's what I have been saying all along.

In that case, let's go to that building.

That's what I have been saying all along.

ARBORETUM RESORT

Let's get off.

Shall we go up?

-What is this? -Do you see anything?

-See anything? -There's nothing here.

-Nothing here, right? -Nothing.

ARBORETUM RESORT

What could it be?

We need the Genius Detective Team for this.

We really need their help on this.

You say we need the Genius Detective Team,

but you become really annoyed when they actually come.

I know.

I'm going to do it. I'll find it.

I will find it.

Where is the tent?

Gosh, this is frustrating.

Could that be it?

-What is it? Do you see something? -I mean...

-Over there. -I checked earlier.

-What is it? -Over there.

-It's a drawing of a house. -It is.

-On that house. You see it? -I see it.

-This is incredible. -That must be it.

-There it is. -It's the same as the drawing.

-That must be it, right? -That must be it.

We need to find one drawing at a time to proceed.

What was the next one?

-It's shaped like a rainbow. -An arch.

-It looks like an arch. -Oh, a rainbow.

A rainbow. Could that be it?

-There it is. -There it is.

That's the one.

Next is a house with two pointy turrets.

-Hold on. -Pointy turrets.

Could that be it?

-There it is. -There is a castle.

There is a castle-like structure.

-Do we need to go all the way there? -Yes, we do.

Gosh, I am so annoyed.

Do we have one drawing left?

-Yes. -We are on the last drawing.

Can I share my speculation?

-Sure. -Did you think of something?

This could be a drawing of numbers.

This could be a drawing of zero between two sixes.

If you put it vertically, you can see the number six.

-You're incredible. -And a zero in the middle.

-Room 609. -It could be Room 609.

It could either be Room 609 or 606.

-I think it's Room 609. -I...

-Me too. -I could be wrong.

-This is... -Let's go with that guess.

-Min-young. -Let's go to Room 609 and 606.

-Okay. -You are a genius.

I never thought this could be a room number.

Try Room 609.

-It's locked. -Is it locked?

Shall we ask around?

-Wait, you have that key. -That's right.

-The key from earlier. -He has it.

-What's that? -What?

There are keys!

-It may not be the right key. -Let's check.

Let's try.

-Let's check. -Maybe a long-term guest stays here.

That makes no sense.

-It's the right key! -Turn it.

It opened.

Why did K ask us to come here?

Try something.

What do you mean "try something"?

Gosh, that startled me.

-Let's look here. -This isn't a regular bed.

-My goodness. -There is a file.

-There it is. -It's a file.

-What is this? -I heard a breaking noise.

-What is it? -There are photos.

These are criminal profiles. From Park Hae-jin to Lee Ki-woo.

-What? -What?

That's right. We met Park Hae-jin in Somuui Island in 2017.

Right.

-Lee Ki-woo. He ran away. -He ran away.

-That's right. -Yes.

"Since 2014.

This suspect leaves a flower behind after killing the victims.

The victims were all found murdered in their sleep."

-Earlier today, K... -The Flower Killer.

"K, it has been a while. I hope you didn't forget about me.

Thanks to you, I am leading a boring life

in a psychiatric hospital.

My desire for revenge is growing by the day

that I can barely sleep.

If you hadn't visited me a long time ago,

I would have become a world-renowned

genius doctor. But all my effort was for nothing.

Just you wait, K. Someday in the future,

I will be sure to visit you."

I think this person killed K.

I've received a text.

What's this?

"It's me, Detective Im. Did you happen to see the news?

'An Ex-convict with a Mental Illness Escapes from a Psychiatric Hospital.

The Police are in Pursuit.'" It's C.

-C? -I think it's C.

-It's C. -Kim Jeong-tae.

He must have caused troubles at the hospital too.

There must be clues inside the hospital.

-Everyone, -Let's go.

let's hurry over to the hospital.

-Is this the hospital? -I think so.

-He escaped from here. -That's right.

Among people we can identify,

two are dead and two are alive.

It wouldn't be easy to escape from this hospital.

Ji Tae-seok is Ji Yoon-ha's...

-Father. -We know that for sure.

-Oh, my gosh. -"Ruthless Teenager Kills a Classmate."

We solved the case of Yoon-ha's death.

I knew something didn't feel right.

-He is Jung Jae-yeong, right? -It's highly probable.

-Did you kill this person? -My goodness.
