[TEAM BULLDOG: OFF-DUTY INVESTIGATION]

[All characters, locations, organizations and incidents appearing]

[in this film are fictitious.]

[Wait, isn't this a Boxcutter Murder?]

[It's a murder case where 22 people have been murdered since the year 2000.]

[This guy is so meticulous and cruel.]

[Why do you think he let Son Ji-young live?]

-Mr. Ham Deok-su? -Yes.

Have you ever seen these ladies?

No.

Have you seen these women by any chance?

I'm not sure.

It's a photo from the crime scene.

He was photographed in the crowd with the other bystanders.

[By the way, Mr. Detective,]

-do you think that lady is okay? -What?

She could get lucky once,

but I'm not sure her luck will continue.

You said you've never seen the deceased Na Jeong-min.

Then what's this?

Oh, this lady?

Unlike her appearance, she handled her shoes roughly.

You crazy...

You are the Boxcutter serial killer!

-Let go of this. -Come with me.

Come with me to the station and confess!

-Come here! -Let me go!

A detective can make a mistake while trying to catch the culprit.

How can they put a new detective

[on a six-month suspension for that?]

[Things are going to get interesting from now on.]

[I'll go all out as an idiot cop.]

Mr. Detective, it's been a while.

It has been ten years already.

Ten years already?

It's only been ten years. Think about the people who died.

So, sit right there and don't do a thing.

Don't go anywhere.

Sorry, ma'am.

Another case occurred after ten years.

Ms. Son Ji-young's testimony is crucial for catching the guy.

Was it this man?

Get out. Get out!

-Get out! -Ji-young. It's all right. Ji-young.

Mom!

-Mom. -It's okay.

I'll catch that guy no matter what.

[I want you to meticulously read through everything again.]

[I'm sure we missed something.]

We can capture the images after dividing them into 60 frames per second

and enhance each image to put them back together.

We might really get a face.

[Episode 11]

Ji-young.

Ji-young.

Get in bed. Come on.

[14J 9113]

I found it.

Mom?

Mom.

[What do you mean?]

What do you mean you didn't have an accomplice?

Are you telling me two people killed

Park Jae-min together?

So there was an accomplice?

I don't want to eat jjamppong.

Gosh, I guess he doesn't like jjamppong.

-Right. -My gosh.

-I got it. -What?

-It's 14J 9113. -14...

And right here.

[14J 9113]

What?

This is

Ham Deok-su.

Yes, Detective Choi.

What?

Excuse me.

-What's going on? -Step back.

Hey, move.

Darn it.

Is she...

Yes. That's Son Ji-young.

The only survivor of

the Boxcutter Serial Murder Case.

He killed her ten years later after letting her go in the first place?

And right in front of our station?

She wasn't murdered here.

Son Ji-young lived in Jangyeon-gu.

He abandoned the body here on purpose.

On purpose?

-Exactly. Why? -Because I'm investigating the case.

This is probably a warning message to me.

-She must be the mother. -Stop, ma'am.

What is this about?

-Oh, no. -This is awful.

Let go of me.

My daughter.

Ma'am, please calm down.

-Calm down, ma'am. -My daughter!

-Calm-- -No!

No. Wake up, Ji-young.

Ji-young, wake up.

No! Wake up!

No, wake up. Ji-young!

We... We barely managed to get by!

We barely managed to overcome it!

We barely managed to bear with it all!

If you hadn't looked for her again,

my daughter wouldn't have died!

I'm sorry. I didn't know this would happen. I'm so sorry.

-Calm down, ma'am. -Bring back my daughter.

-Ma'am, calm down. -My daughter!

Bring me back my daughter!

-Ma'am, calm down. -My goodness!

My daughter!

-My daughter! Bring her back! -Ma'am, please.

My goodness, my daughter!

Excuse me.

I'm sure it was him.

Who?

Did you send out an APB on the car from the restored security footage?

Yes.

I think the search system found the wanted car.

It just moved from Pyeongji Intersection

to Sinwoo-dong.

-Let's go. -Okay.

[Wanted Car Tracker]

Take a left up there.

-Take a right. -"A right"?

Yes.

[Wanted Car Tracker]

What? It stopped 200m ahead.

It should be here somewhere.

-Look! It's Ham Deok-su! -What?

What?

No.

No.

No... No.

No.

-Darn it. Ham Deok-su, you punk! -It hurts!

It hurts! It hurts!

We've detected two people's blood from the bloodstain on the plastic bag.

One belongs to Son Ji-young, the victim.

And the other one is... Here.

[DNA Assessment Report]

[The male DNA is identical to that of Park Jae-min.]

"Park Jae-min"?

It's Jae-min's?

Did they really get murdered by the Boxcutter Serial Killer?

[TEAM BULLDOG: OFF-DUTY INVESTIGATION]

[TEAM BULLDOG: OFF-DUTY INVESTIGATION]

What are you trying to pull?

Are you interested in doing an interview now?

Are you seriously doing this

just to get better ratings?

It's better than all the absurd things you did to murder people.

It's only right that you keep your promise.

I kept my side of the promise and corrected our statement.

So you need to tell me who killed Park Jae-min.

Director Kang.

If it doesn't seem like he'll cooperate,

let's just dislocate one of his shoulders.

No, I want you to do something else.

I want you to pluck those peepers out.

-What? -My goodness.

Mr. Serial Killer, I can see you just got goosebumps.

I guess you're scared.

That's nonsense.

Torturing me won't make me talk.

People who say that usually wet their pants within ten minutes.

No, not here.

Then I'll go outside and get him an adult diaper.

Will ten diapers be enough? Should I get an XL...

Never mind. I'll get a small size.

Come on, guys. Violence won't get us anywhere.

Let's calm down and be rational.

Let me free first.

My gosh, I've never seen a piece of evidence talk.

Stop joking around with me, Director Kang.

I'm the one who needs an adult diaper.

Big and dangerous things are coming.

No, not here!

Then help me out here.

-I really need to go. -Help you with what?

-Are you asking me to help you-- -Just a second.

Hey, what's up?

What? Are you serious?

According to the news,

there's been another Boxcutter Serial Murder Case.

What? That hasn't occurred in the past ten years.

Director Kang.

It doesn't seem like he'll talk from the looks of things.

Why don't we hand him over to the cops?

Even if he tells who killed Park Jae-min,

there's no way we can prove that now.

More importantly, this is unlawful confinement.

I'm not saying this because I need to use the restroom urgently.

Then, should we call Detective Jin?

No.

I'd rather waste my effort.

I can't hand him over to that lousy cop.

What's your plan then?

This is what we'll do.

[Geumpyeong Police Station]

-Hey, call it in now. -Okay.

[I'm the real Locked-room Killer.]

Well, we were zealous and persistent.

Through cutting-edge forensic science that could rival developed countries,

we were able to solve our biggest two cold cases.

We apprehended the Boxcutter Serial Killer

and Locked-room Killer

on the same day. It was indeed a victory for us.

As we have gathered conclusive evidence,

we plan to inquire into other possible crimes

and extract their confessions.

Please refer to the press release for other information.

Is there other evidence?

-Is there another accomplice? -What about...

Read the press release.

-Hold on. -Are you sure?

-I have a question. -Please answer our question.

Where did you get the evidence?

Oh, my. This is all thanks to you, Chief Shin.

As we literally were spoon-fed the Locked-room Serial Murder Case,

we could have been called incompetent and told to hand in our badges.

It could have been a big mess.

And that's when you caught the Boxcutter Serial Killer.

Thank you. It's all thanks to your help.

Oh, my. He's humble too.

I knew it. A graduate of the Police Academy is

indeed extraordinary.

-I hope we meet at headquarters soon. -Yes, sir.

[As we have gathered conclusive evidence,]

[we plan to inquire into other possible crimes]

[and extract their confessions.]

[Please refer to the press release for other information.]

[Is there other evidence?]

What will you do now?

Everything you worked for has come to nothing.

We're supposed to shoot today. We'll have nothing to broadcast!

Why are you always so reckless?

-Hey, Director Hong. -Yes.

Among the topics you have,

-do you-- -What are you talking about?

The only thing I'll miss in my life is a credit card payment.

The material that can turn a crisis into a chance

is right here.

What is that?

Since it already happened, let's be the game-changer.

[How interesting.]

[You're proactively telling us that you didn't kill him.]

[But at least,]

[I didn't have an accomplice. That'd be embarrassing.]

Are you sure

this is legit?

I even secretly confirmed it with an expert.

Okay.

Let's be the game-changers. It's either go big or go home.

What a surprise. You're not objecting.

I should bite if this is a big scoop before someone else takes it.

You won't regret it.

Let me make myself clear.

It's not you whom I trust.

I'm giving you a green light because it's too good to waste it.

Look.

Wasn't that you ten years ago?

The guy abandoning the body here.

Yes.

This is the photo of you entering

the unit next to Park Jae-min's before he was murdered.

And this photo proves that you passed through the alley

on the day of Son Ji-young's murder.

Deok-su, do you know what this means?

You can play dumb or innocent all you want.

It means that you'll end up going to the slammer.

The evidence is as clear as day.

Deok-su.

These people here.

You didn't kill them, right?

But why were you at the crime scenes?

Why did you try to burn the bloodstained plastic sheets?

I killed them.

But you just said it wasn't you.

Did this old man make you do it?

Did Ji Su-cheol tell you to say that you killed them?

What's wrong?

-I need to pee. -What?

I have to pee.

-Hey. -I have to pee.

-Hey, hold on. Wait. -I have to pee.

-I'm going to pee. -You can't pee there!

-Hey! Darn it. -I have to pee.

What are you doing?

The case was closed. Transfer him to the prosecution now.

The case isn't closed.

Isn't that obvious?

I have to pee. I must pee.

As you can see,

he has a level-three intellectual disability.

He's not smart enough

to commit these crimes by himself.

Don't just stand there.

Transfer him right now.

Yes, sir.

Wait. Sir.

-All right. -But sir... No!

-Hey, Inspector Jin. -Where's the restroom?

All right. That way. Okay.

I understand that you made a contribution.

But don't you know that a small mistake can wipe out your contribution?

A mistake?

I'm trying to uncover the truth. How is that wrong?

We have definite evidence.

And he even confessed that he killed them. What other truth?

We couldn't find the boxcutter which is the murder weapon.

And he even recanted his confession just now.

Besides, he's jumping all over the place because he has to urinate.

Do you seriously believe

he's the serial killer who murdered dozens of people?

That's your opinion.

Didn't it cross your mind that

your petty sense of ambition would harm the organization?

Aren't you just worried that I might mar your precious reputation?

Even if that's the case, is that a problem?

It won't be a problem

for someone who believes getting promoted is everything in life.

Detective Jin.

You can try all you want, but you can never go against me.

If you keep this up,

I'll have to take disciplinary measures against you.

If you want to, why don't you just go ahead and do it?

I've got all the time in the world.

I can just go home and get some sleep.

-Gang-ho. -Stop it.

Calm down.

Hey, I'm not worked up right now.

I'm very rational right now. I'm about to befriend Kant.

Hey, this way. Zip up. Okay.

-Detective Min, take him. Go with him. -Yes.

-Gang-ho, stop it. The case was closed. -This way.

The real culprit is still at large. What are you talking about?

I can't stop.

I can't stop for the sake of the victims' families.

Will you keep being stubborn like this?

Look at him. Just look at the guy.

He can't even order his food at a restaurant on his own.

But he was meticulous enough to kill over 20 people?

Do you honestly believe that it's possible?

The organization made a decision.

Our duty is to follow it.

That might be your duty, but it's not mine.

I'm more interested in public safety than some darned duty of a cop.

Five seconds until we're live.

5, 4, 3, 2, 1.

Action.

["Fact Check"]

[Shocking Confession of a Serial Killer]

[The police announced that they have apprehended]

[the culprits of the two biggest cold cases,]

[the Boxcutter Serial Murder Case and the Locked-room Serial Murder Case,]

[and that they have closed these cases.]

[Do Gi-tae, Ham Deok-su]

These two serial killers made everyone tremble with fear.

[Do Gi-tae and Ham Deok-su.]

[The Boxcutter Serial Murder Case]

[The Locked-room Serial Murder Case]

[Especially in 2010, their areas of crimes even overlapped.]

[So the experts have carefully begun to pay attention]

[to the connection between these two killers.]

[We're closed due to personal matters.]

[These two killers could have crossed paths at least once.]

[Please pay attention to the voice you're about to hear.]

[But at least,]

[I didn't have an accomplice. That'd be embarrassing.]

[What you just heard is a comment made by Do Gi-tae,]

[the Locked-room Killer, regarding the Boxcutter killer.]

["But at least, I didn't have an accomplice."]

[Does it mean that there are two culprits of the Boxcutter Serial Murder Case?]

[If what he said was true,]

[is the Boxcutter Serial Murder Case really closed as the police announced?]

Hey, Ji Su-cheol!

[If Ham Deok-su had an accomplice,]

[we can't rule out the possibility of having another victim.]

[Until we reveal the whole truth,]

[Fact Check will not give up.]

Cut.

-Good job. -Good job.

-Good job. -Good job.

Goodness.

Hello? This is Fact Check.

[It says Director Kang Moo-young is in charge, is that right?]

Yes, it is. How can I help you?

All right. Thank you.

[Kang Moo-young Fact Check, Main Director]

Here you go. It's non-alcoholic.

I'm not a kid. Why would you give me a non-alcoholic drink?

Give me a glass of something so strong

that it might kill me.

Is something going on with you?

Four plates of omelet rice

mean something serious.

Nothing's going on.

Gosh.

Until today, three plates were the maximum.

I don't know if I should say this,

but I trust you no matter what you do.

Why would you?

I'm a reckless idiot.

Why?

Because you're trying to make something that doesn't exist in the world.

Justice.

While fabricating evidence.

That's funny.

You can't stand seeing a really bad guy get away due to lack of evidence.

I'll tell you something as your close friend.

I wish you wouldn't try so hard

to atone for your father's mistake.

That wasn't your fault.

That's a bit too--

Stop it.

That's so cringy

that the omelet rice I ate is dancing in my stomach.

In a truly good world, they wouldn't need an idiot like me.

Until that day... Only until then,

I will keep going. Darn it.

Gosh, I'm off.

We'll put three omelet rice and two glasses of liquor on your tab.

It should be four. Count it well.

He'll keep going even when he is 100 years old.

-Sir, we did not make up the story. -Hello.

We're not trying to get attention. We only give you the facts.

Yes.

This jerk is even worse than my ex-husband.

Sir, please don't swear at me.

We're not just baiting viewers. I'm hanging up.

The viewer rating is high,

and we took over the trending search words.

But it looks like there are more losses than gains.

-How's the website bulletin looking? -"Are you writing fiction now?"

"It's a helpless fake show."

"They're the garbage of investigative journalism."

That's what it says.

Some comments say that we should reveal it if it's true

although it's rare to see.

Still, this was the first time our station had

over ten percent of the viewer ratings.

We'll be fine, right?

[Fine, my foot.]

Who are these idiots?

[It's OCM's investigative journalism show called Fact Check.]

So, there's a ruckus over what this random show

babbles about?

They're ruining the case we closed nicely!

[Nevertheless, more than half of the public opinions]

[are against the show.]

Is that so?

Then, take advantage of the situation and hit them harder.

Hand out our press release to other broadcasting stations,

and sue them so that they won't be able to say a word.

-Sue them! [-A lawsuit?]

For defamation by spreading false information.

The plaintiff is the Korean police,

and Fact Check is the defendant.

They're suing us directly without going through the Press Arbitration Commission?

They've already run it by the Press Arbitration Commission

and the Communications Standards Commission.

I dug my own grave because I wanted to get a scoop.

But isn't this suppression of the press?

Yes, it's exactly that.

They're openly putting pressure on our station.

Wait. Are you telling me that my show might get canceled?

How would we stand against a national organization?

We'll be lucky if it ends at a cancelation.

If this goes wrong, you and I will be out of this industry forever.

Thanks to you,

I'll be spending my later years counting the tiles on the wall.

No. I'll prove them I'm right

and countersue them.

Yes. Do something, now that it has come to this.

Yes, it's me.

Find out which jail the police put

their supposed Boxcutter killer.

Okay.

Although he's my husband,

he's so handsome.

If he had been born in this time, he would've debuted in Hollywood.

But I got so many wrinkles from raising your son.

You know what though?

He loves his incompetent parents so much.

Please look after him from up there

so that he won't get hurt.

What are you doing here at this hour?

Are you wiping that again?

Dad's face will get smaller.

You drank, didn't you?

In broad daylight?

You sure are a cop's wife.

I only had two glasses with food.

You can lose your driver's license with that much.

Would they catch me if I drink and walk?

Save your breath.

I have to go out as soon as I get changed.

There's something going on with you, right?

Like what? I'm worried that I can't hold my liquor as well as before.

Stop wiping Dad's face

and wipe Grandfather's too.

His face turned yellow because his face hasn't been washed in a while.

There sure is something.

Mom should've been a detective too.

She's so good. Goodness.

It's unbelievable--

[-Yes.] Gang-ho, did you see?

What do you mean all of a sudden? What did I see?

The show from last night.

The Fact Bomb director bombed us hard.

[The Locked-room Killer Do Gi-tae's interview was aired,]

and he said there was an accomplice in the Boxcutter Serial Murder Case.

-An accomplice? [-Yes.]

That's why it's such a mess here.

[We keep getting calls from reporters.]

Since Ham Deok-su was arrested,

the accomplice

-must be Ji Su-cheol? [-What?]

[-Who?] -It's nothing.

Okay. Hang up now.

Gosh, Pony. Why are you not picking up?

[Director Pony]

[I need to talk to you. Meet me at Red-Zone at 4:00 p.m.]

[A happy correction leads to happy citizens]

Here.

[Visitior Application Form]

-Mr. Ham Deok-su? -Yes.

Prisoners on trial are only allowed one visitor a day.

But someone already applied for a visit, so you'll have to come back tomorrow.

Who came to visit him?

He's over there.

First, thank you for agreeing to do the interview.

[Kang Moo-young, Fact Check]

Oh, you're Kang Moo-young, the director of Fact Check?

Yes.

Do you know our show?

Yes, of course. It's an informative show,

so my wife and I always watch it on TV.

My goodness, really? Thank you.

But not a lot of people know how informative our show is.

-You should tell your acquaintances-- -Deok-su

would never do such a thing.

He's a very kind person.

What's your relationship with Mr. Ham Deok-su?

Deok-su is like a son to us.

So we know him best.

Right, honey?

Yes.

By any chance, did anyone around him seem a little suspicious?

I'm not sure. I...

I think it's because the weather is cold.

I don't think we can continue because of my wife.

Feel free to call me whenever if anything comes to mind.

You should come by if you need your shoes shined.

I'll clean them spotlessly.

-Thank you. -No problem.

-Have a safe trip home. -Okay, thanks.

[Geumpyeong Shoe Repair Shop, Ji Su-cheol]

[I need to talk to you. Meet me at Red-Zone at 4:00 p.m.]

What?

[Please pay attention to the voice you're about to hear.]

[But at least,]

[I didn't have an accomplice. That'd be embarrassing.]

[What you just heard is a comment made by Do Gi-tae...]

My gosh, you startled me.

Do you always have to make such an abnormal entrance?

-What's the matter with you? -What has gotten into you?

Why are you watching our show?

Your show?

You pretty much threw a bomb at the police force.

Are you serious right now?

You know you could get in big trouble if this turns out to be fabricated, right?

It's real.

Our show is based on nothing but facts.

You're the one who fabricates evidence.

Says who?

Who told you I fabricate evidence? Who?

My gosh, I just made it up, but I guess it's true.

Gosh, be quiet.

Let me see the original file.

No. Why would I show you?

Because I need to check something regarding the accomplice.

You know something about the Boxcutter Serial Murder Case,

don't you?

I'll tell you if you show me the original video.

[They were useless in our society like scrap paper.]

[Who are you to judge their lives?]

The police failed to catch the Locked-room Killer for 15 years.

But the four of us managed to catch him.

We should be receiving an award for this, but we're getting sued instead.

Your organization is being absurd.

The people who work there tend to be like that.

What? Why are you agreeing with me today?

[So there was an accomplice?]

Anyway,

so you're saying Do Gi-tae stopped talking here?

Yes, he refused to tell us anything more.

-You hit him, didn't you? -What?

Gosh, no.

I don't hit people. My goodness.

My gosh, I almost forgot.

I left the broth boiling.

The broth.

I really didn't hit him. My gosh.

Come on.

He hit him. I can tell that he did.

I can already tell that you filmed this at the mortician's office.

You guys are civilians.

I can't believe you did this without a cop.

Then you just threw him in front of the police station

because you didn't know what to do?

So what? What about it? Are you going to arrest me or what?

Okay, that's a good idea.

Go ahead and call the other two before I arrest you.

You're really cheap.

I'm sorry.

Please forgive me just this once.

Yes, forgive her.

Okay, fine. Now, hurry up and call them.

The accomplice that Do Gi-tae mentioned. I know him a little.

So, catching Do Gi-tae was like a warm-up.

Now it's time for the actual game. What do you say?

Be quiet before I arrest you.

Well, the four of us showed amazing teamwork

-and caught the Locked-room Killer. -Right.

So this time, we're going to team up with Detective Jin to catch

the Boxcutter Killer, right?

No, that's not what it is.

How do you expect me to trust you guys?

I see.

But doesn't...

Doesn't this place smell like urine?

No, wait. Why... Why did you call us? We're all busy people.

Are you going to arrest us or something?

Yes, I am.

Detective Jin, don't be like this.

-We've known each other-- -For just a few months.

It hasn't been that long. You haven't even grown on me yet.

Come on, Detective Jin.

Let's be rational about this.

We did it for a good cause--

I don't care if it was for a good cause or not.

I'm still extremely offended

by the fact that you did something like this

without even telling me when I'm a cop.

So I'm going to give you a chance to wash away your sins.

If you're given orders by a cop, it's no longer considered illegal.

So you're pretty much asking us

to work as a team, Detective Jin.

Sounds great.

This isn't a team.

I'm your boss.

And you guys are my subordinates. Understood?

My gosh, are you serious?

You're just asking us for help.

Detective Kang! How dare you talk to him in such a rude manner?

That sounds great, sir.

In order to find the culprit, we'll have to figure out the suspect.

-No, that's not necessary. -I see.

We already have

a prime suspect.

Here. It's this guy right here. His name is Ji Su-cheol.

What?

-This guy is... -What? Have you seen him before?

Yes.

I met him when I went to visit the Boxcutter Serial Killer.

Wait a minute. Are you telling me that he's the accomplice?

He just seemed like an ordinary old man who was over 70 years old.

In Canada, there was a serial killer who was 67 years old.

Bruce McArthur.

He killed eight grown men.

And he's not an accomplice. He's the main culprit.

My gosh.

He can't be the Boxcutter Serial Killer.

That's a bit far-stretched.

Exactly. I met him and his wife,

and they seemed like very honest people.

Well, don't let him fool you because he killed all those people.

You guys don't know his true colors.

He's right.

When Detective Jin is that confident about something,

he's always confident for a reason.

Let's just trust him!

Then I'll visit the NFS.

They probably have the victim's autopsy results by now.

I'll go over

all the Boxcutter Case material again.

Sounds great. You guys can let me know

whenever you need my help.

I'll go meet Do Gi-tae first.

It looks like he witnessed the culprit.

It won't be easy to make him talk. I'll go with you.

No, forget it.

Gosh, why does it smell like urine?

My gosh, what is this smell?

He's finally leaving.

That rude little punk.

I think you'll just get in my way instead of helping me.

I'm Tak Won.

That would never be the case.

I came out because I heard a detective from Geumpyeong Police Station was here.

But there's a familiar face.

We're both victims, you know.

I was also tied up for over 30 hours that day.

What a knot.

That's why I can understand the pain and embarrassment

-you must have felt, Mr. Do. -On what occasion did a detective

from Geumpyeong Police Station who has no ties to the case come to see me?

Well, what do you think?

You have a question for me.

The Boxcutter case?

Do you know him?

I've seen him once ten years ago.

But it's not like you're going to reduce my sentence if I talk.

Since there's no way you can get out now,

you should find a way to live comfortably here, don't you think?

Forget about the prejudice that detectives are poor.

Detective Jin is totally rich. He even has a black credit card.

So what will you do for me?

That depends on what you do for me.

Even though it was ten years ago, I still recall it clearly.

That smell, I mean.

[I was walking out after killing an old woman I'd been after for a while.]

[And I smelled blood.]

[So I followed the smell.]

[A loud sound of a machine was coming out of a building.]

[I was walking out after killing an old woman I'd been after for a while.]

[And I smelled blood.]

[So I followed the smell.]

[A loud sound of a machine was coming out of a building.]

And this is where it gets exciting.

That's exactly the face I made back then.

Those two were so entertained by it too.

By "those two," do you mean Ham Deok-su and Ji Su-cheol?

I'd only killed people on my own.

But watching someone else killing was such fun.

Where was that?

No more questions.

Detective Jin, was it?

Let's continue next time.

Mr. Do. Gosh.

It was ten years ago that Na Jeong-min,

the 23rd victim of the Boxcutter murder, was killed.

Around the same time, the eighth Locked-room murder occurred.

At Suin-dong in Dongpyeong-gu.

The Boxcutter Case required lots of care to commit the crime, so--

They wouldn't move from a familiar place that easily.

Even more so since the place was hidden perfectly for over ten years.

That's right.

I'm not surprised to see the instantaneous rigor

since there are so many cuts all over the body.

[Instantaneous rigor: Rigor mortis caused by fear at the moment of death]

[List of evidence]

What?

What it is?

This is security footage of the killer

going in and out of the unit next to Park Jae-min's on the day he was killed.

But do you know what we found in the old man's suitcase?

Wait. Was there any evidence found in the suitcase?

The old lady's hair.

His wife, No Sun-i's.

[Hair from inside suitcase]

[Hair belongs to No Sun-i]

What about it?

It's strange.

This is where Do Gi-tae committed a crime back then.

And this is where we are right now.

He said he didn't walk for long after he came out of the house.

The Boxcutter crime scene should be around here.

But there are so many alleys.

That's why I called for backup.

-There. -Hi, Teddy.

What about the bar?

I must come when Detective Jin calls.

This is more important than making money.

You sure are loyal.

I heard we're here to catch an incredibly bad guy.

I heard it's someone you wanted to catch so badly,

is that true?

Yes, his base is definitely somewhere near here.

We're going to search semi-basement rooms in a 100-meter radius.

It a storage-like room

that has a window on ground level with the sound of a machine running.

-A storage-like room. -Let's split up and find it.

Good. Then we'll go that way.

-I'll take this side. -Okay.

Over there.

A loud sound of a machine was coming out of a building.

[The sound of a machine?]

[Industrial bleach]

Director Kang,

have you heard of the saying, "Dad is going into a bag"?

Yes, people use that saying as an example to explain

a spacing error.

What if the saying, "Grandma is going into a bag",

isn't a spacing error?

What if it's exactly what happened?

No way. Why would an old lady go into a bag?

Deok-su would never do such a thing.

He's a very kind person.

Wait.

Wait, this...

Detective Jin, we meet here, after all.

Deok-su is like a son to us.

The quilted blanket.

Then, the accomplice Do Gi-tae was referring to was--

It wasn't Ham Deok-su.

It was the old man

and the old lady.

What?
