SIGNAL

AUGUST 3RD SEONIL MENTAL HOSPITAL

Final Episode

Senior Lee Jae-han.

You must prepare for the briefing.

Should I get all the documents?

No, I'll get them.

Tae-hyun,

have you contacted all\Nthe suspect's acquaintances?

Go on home now.

-This isn't the place for a kid like you.\N-Hey!

Hey...

KIM YUN-JUNG ABDUCTION BRIEFING

-Lee Jae-han! Hurry up.\N-Okay.

About that blackmail letter,

and the cafe the suspect was in...

Seo Hyung-joon's prints were there,\Nbut only of his right thumb.

If he touched the table\Nor wrote a letter,

his other fingerprints\Nshould also be there.

Strange that it's only the thumb.

So what?

We should look into\NSeo Hyung-joon's mystery girlfriend.

So look into her... yourself.

You like doing things by yourself.

But...

you should watch your back.

You should give it a rest.

We checked all the women\Nin Seo Hyung-joon's life.

You should give it a rest too.

That sucking up to Kim Bum-joo.

I'll head off now.

No,

I need you to do something else.

What?

Do you think I brought you here\Nto catch a measly kidnapper?

Follow Lee Jae-han.

Lee Jae-han has found out\Nwho the Inju case culprit is.

Jang Tae-jin?

But he doesn't have any evidence.

No, there was evidence.

Is that possibly why...

Park Sun-woo\Nwas looking for Lee Jae-han?

Lee Jae-han is in possession\Nof the red scarf

from the crime scene.

He's already sent the scarf\Nto the US and had it analyzed.

Then... what should we do?

That's why I'm telling you to follow him.

Will following Lee Jae-han\Nprovide a solution?

-Why don't we just...\N-You little... why don't we just what?

You want to expose who's really guilty?

If we admit that we fabricated evidence,\Nwe'll lose our jobs.

You think a country bumpkin like you\Nwill find a job at your age?

Or pay your daughter's hospital fees?

Use any and every method.

Bring back the thing\Nthat he should not have.

The radio...

you have to send a transmission.

You have to save...

Detective Lee Jae-han.

Don't talk. Stay still.

I'll call an ambulance.

11:23 p.m.

Always...

the transmissions always come\Nat 11:23 p.m.

Have you eaten?

Yes.

You sure picked a good day.

Transferring on a day like today.

Well.

Senior?

about what I said that time--

I think it'll be resolved soon.

-What?\N-Let me finish it,

then we'll talk.

SEONIL MENTAL HOSPITAL

NOTICE OF BUSINESS CLOSURE

I've got an injured person.

I'm in Joyeong-dong, the Sanghwa Building\Nbasement parking lot. Hurry!

Park Hae-young. Just a little longer.

Detective Lee...

You have to save him.

Lieutenant Park.

Lieutenant Park?

No...

Or...

0.5... is that you?

I'm at Seonil Mental Hospital,\Nthe one that you told me about.

There is a hanging corpse\Nin the manhole behind the building.

It is Seo Hyung-joon,

the Kim Yun-jung case suspect.

But...

his thumb has been cut off.

Someone has killed him\Nand made it look like suicide.

Who are you?

What are you saying?\NSeonil Mental Hospital?

Where is that?

Lieutenant Park?

No...

Park Hae-young.

Pull yourself together, Park Hae-young!

Park Hae-young!

Hurry!

Wake up, Park Hae-young!

No, Park Hae-young.

Lee Jae-han. Wake up now.

-Lee Jae-han!\N-Ah, my head hurts.

Are you awake now?

The Inju case evidence,

that red scarf... where is it?

Give it to me and stop this now.

No matter what you do,\Nnothing will change.

Kim Bum-joo said that?

Did he tell you to bring him\Nthe Inju case evidence?

That red scarf isn't just evidence...\Nfor the Inju case.

It's evidence of Kim Bum-joo's murder\Nof Sun-woo. Do you know that?

What are you saying now?

Park Sun-woo...

I'm certain he committed suicide.

Go now.

What is he saying?

Sun-woo... didn't commit suicide?

I told you to butt out.

You want to try and catch me?

Someone like you dares\Nto go against me?

It was nice to see you try.

How did you manage to get that scarf?

The world...

doesn't always revolve\Naround making life comfortable.

But in the end,\Nyou came back to me dead.

I waited 15 years.

But you ended up dead, Senior!

AUGUST 3RD SEONIL MENTAL HOSPITAL

The future can be changed.

I found evidence for Hye-seung's case.

A red scarf that Hye-seung was wearing

that day.

A scarf...

a red scarf.

It's someone who should never have\Nthat piece of evidence.

Someone made Sun-woo's death\Nlook like suicide,

then took that evidence.

Kim Bum-joo must have taken it with him.

Kim Bum-joo being detail-oriented,\Nhe wouldn't have thrown it out

just anywhere or burned it.

There would be a chance\Nhe'd be noticed.

He would have to get out of the area\Nas quickly as possible.

It would be hard\Nto take care of it in Inju.

Bringing it back to police headquarters

would be too dangerous.

What else is there?

There's a variable...\Nthat I haven't thought of yet.

What is it?

SEIN PHARMACY

A place where many people walk around,

where there's too much garbage\Nto find something that's been thrown away.

A rest stop on the way from Inju to Seoul.

Sein rest stop.

SEIN PHARMACY

Sein Pharmacy.

Ma'am, I'd like to ask you a question.

When were those trash cans emptied?

-Why do you ask?\N-Oh, I'm...

I'm a cop, looking for important evidence.

When were they emptied?

A truck came a while ago\Nand took everything.

Where did it go? Where did the truck go?

What are you doing here?

Excuse me.

I asked you what you're doing.

Can't you hear me?

Let go a second.\NI really must find something.

What do you expect to find\Nin this pile of garbage?

And you can't mess it up like this.\NPlease get out.

-I must find it.\N-Just move a second.

No, get out.

What are you trying to find?

-I'm telling you to stop.\N-I just need to look.

Wait, Grandma.

Is that scarf yours?

Someone threw out a perfectly\Ngood scarf, so I took it.

It was in the trash, right?

NFS-SEOUL NATIONAL INST.\NOF SCIENTIFIC INVESTIGATION

Are you a grown up? Are you human?

-Goodbye.\N-Goodbye.

Hello.

I need to send this package to New York.

NFS-FORENSIC REPORT

The DNA matched.

It matches.

The scarf...

had on it the DNA of two women.

On the reverse of the scarf,

semen was detected.

Besides Park Sun-woo,

the blood

of an unknown male was found.

The blood of an unknown male.

The injury on his hand.

If I want a DNA test

on the unknown male,

I will need a reference sample.

He's not here now.\NYou can't come in like this.

I wronged him last time\Nand I have to thank him for something.

-I'll just leave this.\N-Then give it to me.

You sure are something.

Then let me just write a note\Nto him, right?

I'll just leave this for him.

He's been so good to me.

I practically owe him my life.

I really do.

YOU WERE OUT. THIS IS FOR YOU.\NCHOI SANG-MOOK

The DNA results\Noff a cigarette butt that I sent

and the blood DNA on the red scarf...

are a match.

A match...

Kim Bum-joo,

you're dead now.

Prosecutor Oh Jae-sung.\NIt's me, Lee Jae-han.

I have the evidence. Yes,

it's evidence against Kim Bum-joo,\Nfor murder.

Yes, that scarf.

Back then and even now,\Nthat's always been the problem, right?

Gosh!

Who else knows about this?

I'll ask you one more time.

Does anyone else...

besides Oh Jae-sung know about this?

Oh...

Want to know how I found out\Nwhen you only told Prosecutor Oh?

That's just how the world is.

Don't you realize by now,\Neveryone is in the same boat?

This is your last chance.

Give up.

If you promise me that you'll give up,\NI'll end this now.

I don't want to kill a fellow cop.

No.

You have no intention\Nof letting me live anyway.

Do as you please.

Do it.

You mean, you don't want to give up.

-Get rid of him.\N-Yes.

You can't.

Isn't it enough that there's no evidence?

The data is there in the US.

We're done for\Nif he asks for the results again.

Still, this isn't right.

-How could we do this to a fellow cop?\N-A fellow cop?

Do you think he considers you\Na fellow cop?

If you let him live,\Nboth you and I are dead.

Okay.

-Sir, you can't!\N-Are you crazy?

You're the one who dragged him here.

-Please don't.\N-Move!

-Get him.\N-No, you can't! No!

Get it together, you punk!

If he gets out of here,

you'll rot in jail for years

for kidnapping and accepting bribes.

Then your daughter will die.

Make your choice.

Lee Jae-han or your daughter.

Make your choice!

-Let Ahn Chi-soo end him.\N-Yes, sir.

It changed.

Park Hae-young, are you okay?

It changed.

We'll be at the hospital soon.\NHold on a bit longer.

The transmission changed.

A long time ago,

my first transmission...

I told him not to go to\NSeonil Mental Hospital.

You are the one who told me\Nabout this place.

But this time,

I wasn't the one

who told him about it.

August 3rd,

Seonil Mental Hospital.

Don't go there.

Because the transmission changed,

the past could have changed too.

When was the last time...

you saw Detective Lee Jae-han?

August 3rd.

He left to go investigate\Nthe Kim Yun-jung case.

Is it the same as before?

Has anything changed?

No... nothing.

I think it should be resolved soon.

-What?\N-Let me finish it,

and let's talk then.

You're right.

I'll be back for sure.

My last memory of him... is different.

I'll be back soon.

My memory has changed.

I'm certain...

he just said to wait until the weekend.

That it would be resolved soon.

He said to me\Nthat he'd come back for sure.

The past...

has already changed.

Everything...

will remain a cold case if I die.

Both the Inju case and Sun-woo's case.

And Cha Soo-hyun...

You told me to wait for you!

I waited so long for you.

I will go back.

We have a casualty.

11:23 p.m.

The time that Detective Lee died.

Rather than fearing death...

you were more afraid\Nthat those cases

would remain unsolved, right?

Is that the desperation you felt

when you sent me the transmissions?

Detective...

use that determination

to live.

Not using the transmissions,\Nbut your own determination and will.

Don't give up.

EACH PAIR OF HANDCUFFS\NCARRIES 2.5L OF TEARS

-Jae-han.\N-Hey, what took you guys so long?

How could we find your exact location?\NWe scoured the woods.

Kim Bum-joo! Go get Kim Bum-joo!

Hold on a moment.\NThe ambulance will be here.

We'd better get going.

Your head. Watch your head.

Senior!

What happened here?

Are you crazy?

You told me\Nto avoid criminals with knives.

What is this?

What am I going to do?

Let's go.

I kept my promise.

I stopped by because you're sick.

I wanted to see you wake up.

I had to go because of the restaurant.

Make sure to eat the rice.

Mom.

As for the abduction of Kim Yun-jung\Nfrom Jinyang Elementary School,

the real culprit's been arrested.

Yun is a nurse\Nat a psychiatric hospital.

It was discovered\Nthat she kidnapped Kim Yun-jung

because of credit card debt.

Yun has murdered\Nthe missing Seo Hyung-joon,

causing great shock to everyone.

Sun-woo did not do it.

What do you mean?

Sun-woo didn't do it?

That's right.

Sun-woo...

was not guilty of the Inju rape crimes.

Also...

he was trying to find

the real Inju case culprit.

And he was murdered for it.

Sun-woo...

wanted his family\Nto live together again.

Because of that...

he ended up getting killed.

I apologize...

for Sun-woo's death.

And for being unable to expose\Nthe Inju case perpetrator.

I'm sorry.

Sun-woo!

Sun-woo!

Mister Policeman.

Thank you.

Thank you very much.

Okay.

Detective Lee Jae-han?

He survived...

and lived.

Welcome.

Do you need a watch fixed?

Detective Lee Jae-han...

Do you know my son?

Yes.

Where is the detective now?

I don't know how a young man like you\Nknows my son.

My son has been missing.

It's already been more than 15 years.

What are you doing? Bring it now.

What are you doing? Go over now.

Yes.

What can I help you with?

Oh, what happened over here?

What happened here?

Which department are you from?\NDo you know me?

-I'm Lieutenant Park Hae-young.\N-Who are you?

You can't just barge in here.

BUKDAEMUN PATROL DIVISION

What in the world...

-What are you doing? Get him out of here.\N-Okay.

You can't be in here.

What a strange guy.

-Do you know him?\N-No.

Hey, don't let just anyone walk in here.

I told you, these are different.

Where is it?

I told you, I gave it to you.

If you gave it to me, why don't I have it?

You're the one who's\Nnot keeping things in order.

Look at you, talking back\Nto me like that.

Who are you...

This isn't a place\Nthat people can just walk into like this.

You're Lieutenant Park Hae-young,\NTeam 3 leader, Bukdaemun Patrol Division.

This is your desk, right?

Is...

is Detective Cha Soo-hyun around?

Why are you looking for her?

She's always saying she has no money.

Did she sign up for insurance again?

Or get a new car?

Oh, I'm...

I'm Lieut. Park Hae-young,\NBukdaemun Patrol Division.

Lieutenant?

Why didn't you tell us your rank\Nfor a start?

Civil servants can get in trouble\Nif they don't say their rank.

I have something important\NI need to discuss with her.

Has she gone far?

We don't know. She left suddenly\Nand I haven't seen her.

Let us know if you find her, okay?

She's not answering her phone,\Nshe's not home.

We're so busy. Where the heck is she?

Anyway, send those results again.

I've done it so many times. I won't again.\NYou always lose them. You can't do that.

I'm telling you, I didn't get them!

I give them to you and you lose them.

Are you waste disposal or what?

I didn't get them from you at all.\NWould I lie to you about it?

Oh! Why are you here on your day off?

What is it?

What are you looking for?

That radio.

That old radio with no batteries.\NDon't you remember it?

-I don't know what you're talking about.\N-I brought it in that time.

You brought in a radio, Lieutenant?

You never did that.

Hello.

It doesn't suit me anymore.

Coffee?

-Two coffees, please.\N-Okay.

Soo-hyun, wait!

Cha Soo-hyun!

Just wait, would you?

Oh, wait!

Gosh, wait.

It's your first date, after all.\NAre you going looking like this?

What?

I could get called out while I'm out.

-Should I wear a skirt and heels then?\N-This still isn't right!

Spray this on at least.

Guys love this stuff.\NThey will just drop dead.

-Forget it.\N-What do you mean, forget?

I want my own room\Nby the end of the year, okay?

Good luck!

Go back inside.

If I get it to myself tonight,\Neven better.

Hello.

Hey.

-Come outside.\N-Outside?

Where?

Don't you like pork rinds?

It's not that at all.

Wow, that looks good.

Does something smell weird to you?

Is it this?

Are you a regular here, Senior?

No, not me, but someone I know well.

Did you come to see that little kid?

It's been a while since he's been here.

He's living with his mom and dad now.

Yes, I know.

I can take that.

Who is this little kid?

It's just someone.

It's not...

-What?\N-It's not your...

it's not, right?

Just drink.

Are you still looking for Kim Bum-joo?

You've done more than enough.

You should...

let someone else look for him.

Kim Bum-joo is not a big fish.

What does that mean?

There's someone else\Nwho truly deserves punishment.

The person behind it all,\Nthe one who made everything happen.

The real mistake must be corrected

in order to change the past.

And you can change the future too.

You should eat.

I've never seen you with your hair down.

I've had it down a few times.

What are you staring at like that?

Oh my.

That small kid from way back\Nis already old enough to drink soju.

Time goes by so fast.

Was that the last time?

Huh?

Back then...

that detective...

Yes.

He came once with that woman,\Nand I never saw him again.

Ma'am!

-Hello.\N-Do you have pork rinds?

Yes, we have those.

Detective...

exactly what...

what happened?

What?

Where are you?

I'm in Kyungjin-dong.\NContact the others and hurry up.

Senior!

Where exactly in Kyungjin-dong?

Hey!

Get up.

I told you, didn't I?

I wouldn't let you get away.

So what?

Do you think the world will change\Nif you catch me?

It's better to live as a dog

than to whine and live,\Ncomplaining that it's a dog's world.

No, it's not you that I want.

I need to catch another\Nto change the world.

The uncle of the principal offender\Nof the Inju case.

Congressman Jang Young-chul.

He knew exactly\Nwhat his nephew had done.

And he got a weak child killed

just to cover it up.

That son of a bitch!\NIt was him, wasn't it?

What about it?

Because he lives that life,,

he has the power that he's got.\NThat's how the world works!

That's just the problem.

It will all be done again,\Nthen 10 or 20 times more.

Those same crimes will be committed\Nover and over again.

Him covering them up with power\Nand silencing people with money.

Using crime to fabricate lies!

That's why I'm trying to stop it here.\NI'll catch him with my bare hands, okay?

You?

Not the police, not the prosecution...

even the president can't mess with him.

So what can one\Nviolent crimes detective do?

The corruption involved\Nin the Jinyang new city development.

The disk you gave to the prosecutors\Nafter manipulating the data.

Even if you don't have the original,\Nyou must have a copy.

Don't tell me you don't have one.

I know a nasty, cunning person like you

would have made a back-up.

Where is that disk?

Huh?

Get them!

You punk.

November 20, 2000.

In a warehouse in Kyungjin-dong,

former Chief of Detectives\NKim Bum-joo's body was discovered.

The multiple injuries on his body\Nindicate that he was in a violent fight.

It is assumed that he was murdered.

Before he was murdered,

he met violent crimes detective,\NLee Jae-han, of Jinyang precinct.

Large amounts of Lee Jae-han's blood\Nand DNA were found at the crime scene.

Suspect Lee Jae-han's whereabouts\Nhave been unknown since November 20, 2000.

His car was discovered

on Highway 13.

The case was closed\Ndue to statute of limitations.

Kim Bum-joo was found dead\Nin a warehouse.

Detective Lee Jae-han was named\Na suspect, but he is missing.

Detective Lee wouldn't kill Kim Bum-joo,\Nan important witness and suspect.

Someone killed Kim Bum-joo\Nand framed Detective Lee Jae-han for it.

Who would do this?

Hey!

Jae-han? Lee Jae-han!

Jae-han!

Lee Jae-han!

Lee Jae-han!

-Senior!\N-Lee Jae-han!

If only I had the radio...

If only I had it...

Lieutenant Park.

There could be a way,

even without the radio.

But I am certain that something happens\Nin Hongwon-dong.

It was written in your own notebook.

My notebook?

There was a memo

inserted in the back of your notebook.

You had written about the 1989\NGyeonggi Nambu case.

And the 1995 larceny case.

I had written that? Are you sure?

Detective Lee knew\Nthat I read this memo in the future.

The last message

he left me for the future.

1989 GYEONGGI NAMBU CASE\N1995 THE BIG STEAL CASE

No one would know this.

But I know these numbers.

1999 INJU STUDENT CASE\N32-6

Hae-young, what are you doing here?

I went to see you briefly yesterday.

How are you feeling? Are you okay?

Eat.

I...

There's something I wanted to ask you.

You know...

the detective that solved Sun-woo's case\Nwhen I was young?

Detective Lee Jae-han.

Did he by any chance...

Did he by any chance\Nleave anything with you?

How did you know about that?

I got a call from that detective.

He said he'd mail me something\Nand it was important.

He asked me never to tell anyone.

He asked me to hold on to it\Nuntil he came for it.

He's someone we're very grateful to.

That's why I never threw it out\Nand held on to it.

I assumed he'd come for it someday.

I'm not sure if you'll get this letter,\Nlieutenant.

I truly hope that you do.

This letter is the last way\NI can reach you.

Do you remember...

what you said to me\Nabout the first transmission?

I didn't send the transmission first.\NIt was you, detective.

You're saying\NI sent the transmission first?

Yes. You said this to me back then.

That the transmissions would start again.

And to convince you back in 1989.

-Lieutenant Park.\N-Who are you?

Back then, when you sent\Nand received transmissions from me,

it was a Lieutenant Park Hae-young\Nwho didn't know me.

Ultimately,\Nthe transmissions between us...

Do you suppose they looped around\Nlike that again?

However, I no longer received\Ntransmissions after I survived.

I waited, hoping they might come again.

I should have died, but I lived,

so perhaps our fate has ended also.

My radio has yet to make a sound.

Mister Policeman.

Thank you.

Thank you very much.

I had a thought that day.

If the person who truly deserves\Npunishment is not punished...

I began to think that something like this\Ncould happen all over again.

As for the enclosed disk...

it has on it data relating to\Nthe 1995 corruption case.

Jinyang new city development.

I thought a lot about who and where\Nto send this information.

But... in the time that I live in...

I could not think of anyone.

No matter who I sent it to,

that person would be in danger.

Or... the evidence would disappear again.

News of the Jinyang corruption\Nis spreading.

But the world you live in\Nmust be different.

Your signature was found\Non the files released online.

It's clearly a company document.\NIs this true?

Many people are starting to think\Nyou should resign.

What are your thoughts?

The development of Jinyang\Nhelped citizens with housing issues.

The region became economically developed.

It was an innovative and successful\Ncity development enterprise.

Accusing the business as corrupt

is like accusing the government\Nwho oversaw it.

What is more, it is an insult\Nto the Korean people.

Let's go now.

In order to calm the public,\Na special prosecutor

will be assigned to case.

If the investigation reveals\Neverything to be true,

this nation's political and economical\Nentities will be in deep trouble.

The files that were leaked online...

were the very documents\Nthat the detective took 16 years ago.

Do whatever you have to do.

-Find it.\N-Yes.

At the very least,

I believe your world is a place\Nwhere the wrongdoer gets punished.

I want to believe that.

You, in the future, are my last hope.

I think this letter will be\Nmy last words to you as well.

Please be well and healthy.

I hope you're happy.

Hi. This post mark is from here, right?

Would I be able to find out\Nwho sent this?

I'm looking for a missing person.

November 24, 2000.

Can I look up any unidentified remains

or skeletal remains around here?

What's up? Can't you find anything?

No.

It's a relief.

There's nothing.

Have you ever seen him in this area?

I'm not sure. I don't think so.

He's tall, about 185 centimeters.

If you see someone similar,\Nplease call me.

I will.

Detective Cha.

Do you... remember me?

Once I pulled myself together,\NI realized the cold case squad was gone.

No one remembered me.

So I went to Jinyang Precinct\Nto look for you.

They said they couldn't contact you.

But I still tried to contact you.

You couldn't find my number\Nin your saved contacts.

Did you do that too, detective?

Yes. Like you said,

everything changed.

I gathered myself.

And I went to the emergency room.

They said there were no patients\Nnamed Park Hae-young.

I even went to your place.

I saw your mother.

She said you were sick and sleeping.

It was a relief.

What about Detective Lee Jae-han?

I remember it.

All of it.

I know I received Senior's orders.

But from the outside,

I didn't have that memory.

The fact that Senior went missing\Ndidn't change.

And for the past 15 years...

I've been looking for him.

One more thing changed.

A call.

After Senior went missing,

I received a phone call.

Jinyang Precinct, Violent Crimes.

Please speak...

Hello?

Hello?

Senior?

Is that you?

It's you, isn't it?

Senior!

Hello?

This is Jinyang Precinct,\NViolent Crimes, Team 2.

031-567-8236.

Can you trace the call\Nthat came to this number?

PAY PHONE JUNGHYUN SANGIN-GU

He didn't say a word.

But I knew it was him.

No...

I knew in my mind that it was him.

I don't know him.

Did you get that call...

on November 24, 2000?

Yes.

He sent a letter from here\Nto me on that same day.

It was an envelope\Ncontaining important evidence.

The post office deletes their records\Nevery year,

so I can't confirm who sent it.

But I know it has to be Detective Lee.

This was the right place.

Senior was around here somewhere.

I'm sure he was here 15 years ago,\Nbut I don't think he is now.

Why would he have sent this to me\N15 years ago?

I think he knew that he was going to die.

So...

he wanted to leave behind\Nthis bit of evidence.

Grabbing onto his last chance of hope,\Nhe sent this to me.

There's no proof that he's dead.

I hope that he's alive too.

But...

But he wouldn't stay out of touch\Nwith his family and friends for 15 years.

He wouldn't hide away like this.

If he was alive...

I'm positive\Nhe would have contacted someone.

What if he had no other choice?

What if he could not contact anyone?

Like he wasn't fully conscious.

-Detective...\N-There's no proof that he's dead.

If that's the case,\Nthen he could be alive too.

JUNGHYUN NURSING HOSPITAL

Junghyun Nursing Hospital?

What is it?

I got this text a few days ago.

It was a strange text.

I looked into all the hospitals\Nnamed Junghyun.

I couldn't find much.

FEB 5. DO NOT GO\NTO JUNGHYUN NURS. HOSPITAL

Senior, you, and I...

only the three of us know about the radio.

August 3rd, Seonil Mental Hospital

August 3rd,

Seonil Mental Hospital.

You can't go\Nto Seonil Mental Hospital.

ON FEB 5, DO NOT GO\NTO JUNGHYUN HOSPITAL.

At smaller treatment centers,

you can be admitted\Nwithout confirming your identity.

You can also be admitted for a while too.

That doesn't make sense.

Detective Lee has been on the run\Nfor murder for a while.

He can't even use a credit card.

How could he hide out here for 15 years?

Unless...

he has someone helping him.\NIt would be impossible.

Someone helping him.

For 15 years...

There's no way he wouldn't\Nhave contacted family or friends.

KANGWON - SEOUL

Welcome.

Do you need a watch fixed?

Detective Lee Jae-han...

Do you know my son?

This never made sense from the start.

Ever since I received transmissions

on a radio with no batteries.

So...

I don't need to feel disappointed already.

JUNGHYUN NURSING HOSPITAL

I don't know what awaits me\Nat the end of this road.

Though I've never met him...

I may meet my closest friend.

Or...

a dangerous fate may await us.

I can't do anything now.

If...

Detective Lee Jae-han\Nis the one who sent this text,

it would be dangerous to go there.\NYou know that.

He died on August 3rd

after going to Seonil Mental Hospital.

Detective Lee continued\Nto hold on to that radio.

I no longer received\Ntransmissions from him.

But he could have started up\Nwith someone else.

Like before...

he could have transmitted\Nto someone in the future.

And that future person...

warned him about February 5th,\Nabout Junghyun Nursing Hospital.

He may have received a warning\Nthat something dangerous would happen.

No. It could be the opposite.

He went to Seonil Mental Hospital\Neven after what he'd heard.

He might assume we would too.

And that's why he sent that message.

What are you doing?

There's only one thing I'm sure of.

The transmissions started

through one person's determination.\NThat voice over the radio

taught me one thing.

It will work out if you don't give up.

Is it like that there too?

If you have money and power...

can you get away with everything,\Nno matter what horrible thing you do?

It's been 20 years, after all.

Something must have changed.

If you've done something wrong,

whether or not\Nyou have money or power...

you should be punished accordingly.

That's our job as the police!

I won't give up.

No matter what happens,

I will see it to the end.

A detective...

can't lose focus.

The real mistake has to be corrected

in order to change the past.

And you can change the future too.

If you don't give up...

the work of toppling the corrupt power\Nthat seemed so insurmountable...

and meeting the person you wandered\Nand searched for 16 years...

is all possible.

If you don't give up...

there is hope.
