Tunnel (터널)

I'm going to catch you.

Cause of death is excessive bleeding.

This is the first laceration, and the second.

How are these two wounds different from each other?

Take a moment to look at them.

Yes, Lieutenant Kim.

Professor, can I take a look at the medical examination report on the corpse

found in Hae In River?

Hae In River?

I couldn't even find any photos from the crime scene.

You couldn't find them? All right, I'll look into it.

I have students working at the National Bureau of Investigation.

By the way, are you outside? I hear the rain.

I'm at Hae In River.

I don't see anything, as expected.

The fact that there's nothing could be the clue.

I'll get back to you soon.

Please look into it. Okay.

Yes, Professor. Did you forget anything?

Are you busy?

Yes.

I called you to ask if you aren't coming this year again.

Do you still not get why I don't go to Mom's memorial service?

Seon Jae, your grandfather is in critical condition.

You have to come to the hospital right now.

Seon Jae, you've just missed him...

Grandpa.

[I'M SORRY I COULDN'T CATCH THE KILLER... MY POOR DAUGHTER...]

But he used to tell me Mom died because she was sick.

You couldn't do anything, Dad.

You never cared about me anyway. I won't go to medical school.

I don't have anyone I want to save!

I'm going to catch the killer myself.

Seon Jae!

I have no hard feelings toward you. Thank you for raising me.

How could you say that?

Seon Jae! Seon Jae!

From the day I found out how Mom died, I never went to her memorial service.

What's the point in giving a service when we haven't caught the killer?

Who are you doing it for anyway? For yourself? Or for my stepmother?

Seon Jae...

Give the memorial service if you want.

I'm going to catch the killer.

Sergeant!

- Take a look at this. - What is this?

- The way I can go back. - What?

But this is a photo from a speed camera.

Huh?

This was sent to Park Kwang Ho, born in 1988.

December fourth. Do you know what day that was?

The day I came here.

He was the first guy I met since I came here.

What?

Hey! I'm a police officer. Open up. I said, open up!

So you met this guy? What kind of coincidence is that?

It's not a coincidence. I was right about this.

I have to first find him in order to find out why I'm here

and how I can get back.

But the thing is, all his contact information and photos are gone!

A person went missing, but there's no one looking for him!

I heard this guy has no family.

Even his phone is turned off.

I registered his phone for the location tracking service.

I will search for his car too.

We absolutely have to find him, okay?

Oh, and... Yeon Sook.

Have you found her?

Well, not yet...

Hey, you said it won't take long to find her!

You said it'd be quick! You said you could find her!

I really miss her, you punk!

Rookie, you wouldn't know because you're not married yet.

I've been married for 25 years, Sergeant.

Oh yeah, you must be married by now...

- Is she pretty? - Well, she used to be.

This is Su Jeong. Thank you for catching the guys who hurt my brother.

I hope you're not hurting anymore.

What are you doing, Professor Shin?

It's the first time I saw such an expression on your face.

That was a smile, right?

Who is it from?

A girl I met from my last case.

The girl who had temporary aphasia?

Are you okay?

She'll get better.

Not that girl. I mean you, Professor Shin.

Don't just study other people's minds. Look after yourself first.

Go on a date with a guy on a day like this, when you have no classes.

Are you seeing anyone? Is there any guy who's pursuing you?

Well, I do have a stalker.

What?

It's raining heavily.

Oh, Team Leader.

- That punk! - Hey!

We just got a report that someone was found dead at the highway service area.

That's why he was like that.

Team Leader, why are you coming with Rookie?

How can you sit around when a person was killed?

Are you here on a vacation? Have some common sense!

- Team Leader, I'm off. - Huh? What?

I met him in front of the building. Let's go to the service area.

But Min Ha is on his way here... He's weird today.

It's raining too. Gosh, I don't want to go out.

Isn't that the guy Lieutenant Kim lost?

It's hard to know how many women he killed.

He's the most notorious serial killer.

Jung Ho Young?

I heard his name is Jung Ho Young. The killer you've lost.

What is it that you want to say?

I was just curious. I can't even ask questions?

Why are you so obsessed with him?

Mr. Jung Ho Young.

Did you kidnap and murder Nurse Yang Yoo Jin from Hope Hospital?

This is the security camera footage taken in front of the hospital.

The victim was last seen getting in your car.

And after two months, she was found dead.

How did it feel when you killed her?

Do you enjoy seeing a woman suffocating? Do you get aroused by that?

Want me to tell you something really funny?

I've killed more people.

I wish you could find them, Detective.

Sorry, but you're not that smart. Stop writing a novel.

The case no one knows about and that is not even in the record.

[JUNG HO YOUNG. HWA YANG, SUJEONG TOWN 23]

He doesn't live far away.

"The case no one knows about and that is not even in the record."

My mother's case was not in the record.

Jung Ho Young.

Let me use the bathroom.

Seon Jae! Seon Jae!

Are you okay? What happened?

Jung Ho Young... Jung Ho Young...

Jung Ho Young!

Detective Oh! Detective Oh! Call 911! Hurry!

It's not like you ever answered my questions anyway.

What's the occasion? Why are you dressed in black?

People might think you're going to a family memorial. Is someone dead?

Shut up.

You punk. Don't give me that look. You don't scare me.

Hold on. Why are you guys here?

Can't you tell?

Oh...

- Where is it? - Right here. Please follow me.

The victim is Choi Hong Seok. He's a truck driver.

He called the police asking for help and then hung up. He didn't call back.

So we tracked his location through cell service tracker.

He was already dead when we found him, as you can see.

His head is crushed.

The killer must have had strong personal feelings to smash his head like this.

- How many people were inside? - Six, including the store owner.

How many left before we got here?

None that I know of. We got here right away after we received the report.

And... the rainstorm doesn't make escape easy.

Look. It's raining cats and dogs.

Is his truck the huge vehicle parked outside?

Yes.

Seems like he was a pretty good fighter.

The killer probably hit him from behind, since he fell down without resisting.

What is it?

I'm Lieutenant Kim Seon Jae from Hwa Yang Violent Crimes Unit.

Who is it?

Who's pretending like nothing happened after committing a murder?

I guess I should bring two more.

It won't move!

Team Leader, the road is blocked! You've got to go around.

There's a bypass!

It's even worse there! The bridge is completely submerged.

The water will go down tomorrow, so we're getting ready to leave.

We'll see you later than.

This is an emergency weather forecast.

The national weather forecast has changed the Flood Watches they issued

to Seoul and Gyenggi Province at 9:00 a.m. today to Flood Warning.

Geez, I really need to leave!

Are we stranded here?

I wonder if the killer is really among us.

Nonsense.

Yes, Team Leader. Where are you?

Hey.

The roads are flooded!

- So forensics can't get here? - No.

Why is that punk... I mean, why is he calling you?

Then we've got to find a way...

- Hello? - Hello?

Why? What did he say?

- No one can come. - What?

We're stranded here.

A number of regions have been shut down due to road closures and landslides.

The heavy rain is expected to continue until tomorrow.

The killer is stranded here too.

Please prevent destruction of facilities, and stay safe.

- Do you want to stay in the car? - You go, if you want.

Gosh...

No big deal. Let's get the killer before the rain stops.

Do you know what the real problem is here?

I'm not able to attend the Deputy Minister's son's wedding!

Who gives a crap about that driver's death anyway?

What?

A person was killed and that's how you talk?

Is that why you killed him?

Stop making ridiculous assumptions.
