[August 3, Seonil Mental Hospital]
Jae Han.
They're ready for your briefing.
Shall I get the printouts?
No, I'll get them.
Hey, Tae Hyun. Did you call...
Seo Hyung Joon's acquaintances?
I got it.
Go home.
This is no place for kids like you.
Hey. You...
Jae Han, hurry up.
Okay.
Look. Seo Hyung Joon's fingerprints were found on the threat letter...
and at the café where he asked to meet to get the cash.
But they were all right thumbprints.
If he touched the table or wrote the letter,
we should've been able to find other fingerprints.
It's weird that we could only find the thumbprints.
- So what? - We need to look more into...
Hyung Joon's unknown girlfriend.
Do whatever you want, but do it alone.
You like working alone.
But...
you better watch your back.
Why don't you just stop?
We looked into all the women he knew.
Why don't you stop?
Stop grovelling to Director Kim Beom Joo.
I'll go and check the site.
No.
I have another job for you.
Pardon?
Do you think I brought you here just to catch a kidnapper?
Follow Lee Jae Han.
He knows...
the real assailant of the Inju case.
Jang Tae Jin?
But he won't be able to prove...
You're wrong. There was evidence left behind.
Then...
did Park Sun Woo want to see Jae Han...
because of that?
The red scarf that was left at the scene...
Jae Han has it.
He sent it to the USA already and had it analysed, too.
Then...
what should we do?
That's why I'm telling you to put a tail on him.
Well...
I don't see how following him around...
will solve anything.
- How about... - You fool.
How about what?
How about we reveal the real culprit?
If the truth gets out,
we'll have to return all the money we took and resign.
Do you think...
someone like you can find another job at your age?
What about your daughter's medical bills?
Do whatever it takes...
and retrieve that evidence.
The walkie-talkie...
I have to talk to Detective Lee.
I have to...
save him.
Stop talking. Stay still.
I'll call an ambulance.
It's at 11:23pm.
He always...
contacted me at 11:23pm.
Have you eaten?
Yes.
You chose such a perfect day...
for you to transfer here.
I...
Jae Han.
What I said before...
I think it'll be sorted out soon.
What?
Let's talk...
when this is all finished.
(Seonil Mental Hospital)
(Notice of Closure)
Someone's badly hurt!
We're in the underground parking lot of Sanga Building in Joyong-dong.
Send us an ambulance quickly!
Park Hae Young. Park Hae Young. Please wait just a bit.
I have to...
I have to save Detective Lee.
Lieutenant Park.
No...
Or...
is it you, Rookie?
I'm at the Seonil Mental Hospital that you mentioned.
There is a corpse hanging in the manhole behind the building.
It's Seo Hyung Joon, the suspect of Kim Yoon Jung Kidnapping Case.
But...
his thumb is cut off.
Someone killed him and staged it as if he committed suicide.
Who are you?
What are you talking about?
Seonil Mental Hospital?
Where is that?
Lieutenant Park Hae Young?
No...
Park Hae Young! Park Hae Young!
Hae Young, wake up! Park Hae Young!
Park Hae Young!
Hurry!
Hae Young, wake up! Park Hae Young!
No! No, Park Hae Young! Park Hae Young!
Lee Jae Han. Lee Jae Han. Wake up.
- Lee Jae Han! - Gosh, my head hurts.
Are you all right?
Where is the red scarf that could lead...
to the real assailant of Inju Gang Rape Case?
Just give us the evidence and stop it now.
No matter what you do, nothing will change.
Did Kim Beom Joo tell you to do that?
Did he tell you to retrieve the evidence for the Inju case?
That red scarf is...
not only the evidence for the Inju case,
but also for Beom Joo's murder of Park Sun Woo! Understand?
Gosh.
What did you just say?
Park Sun Woo...
definitely committed suicide.
You stay out of it.
What is he talking about?
Didn't Sun Woo commit suicide?
I told you to stay out of it.
Do you want to catch me?
How dare you?
At least you tried.
How did you get that evidence?
The world doesn't...
always turn in your favour.
You came back dead.
I waited 15 years,
but you're going to die.
(August 3, Seonil Mental Hospital)
The future can change.
I found the evidence for Hye Seung's case.
It's the red scarf that she was wearing when it had happened.
Scarf...
Red scarf...
Someone who shouldn't have the evidence...
staged Sun Woo's suicide...
and took it.
It's definitely Kim Beom Joo.
Knowing that he's detailed, he wouldn't have thrown it out...
just anywhere or burnt it.
It's because people could see him.
He had to get away from the crime scene as soon as possible,
so he wouldn't have gotten rid of it in Inju.
But it must have been too dangerous for him to bring it to the station.
What else is there,
Lieutenant Park?
There must be a variable I couldn't think of.
(Saein Service Area)
What is it?
(Saein Pharmacy, First Floor, Saein Service Area, Gyeonggi-do)
It's a place where strangers come and go,
a place where the garbage can't be found again once it's emptied.
It's the service area situated on route from Inju to Seoul.
Saein Service Area.
(Saein Pharmacy)
Saein Pharmacy.
(Saein Pharmacy)
(Waste)
Excuse me, could I ask you something?
When did they empty the garbage?
Why do you ask?
Oh, right. I'm a detective. I'm looking for an important evidence.
When did they empty it?
The garbage truck came earlier and took everything.
Which way? Where did the truck go?
What are you doing there?
Excuse me.
What are you doing here?
Don't you hear me?
Let go of me. I have to find something.
What could you possibly look for in garbage this big?
You're making a mess here. Get out now.
- Come on. - I have to find it.
- You can't... - Wait.
- Let me look. I need one thing. - Get out now.
- Just one thing. - What on earth are you looking for?
- Let go. - Get lost.
- Please give me a minute. - No.
Just...
Hang on.
Excuse me, Ma'am.
Is that your scarf?
Someone threw it away,
so I took it.
It was thrown away, right?
(National Forensic Science)
How can you call yourself an adult?
Are you even human?
- Thanks. - Have a nice day.
- Hello. - Hi.
To New York, please.
This means "Can".
"Can".
Two female DNA profiles...
were found on the scarf.
On the back of the scarf were...
traces of semen from an unknown male.
Blood from another male...
besides Park Sun Woo was also found.
Another male's blood?
He had a cut on his hand.
To identify the other male,
please supply...
a DNA sample for comparison.
(Sample for comparison)
You can't come in here. He isn't in.
I need to make up for my mistakes,
and I owe him. I'll just put this on his desk.
I'll give it to him.
Goodness.
Then...
let me write a note at least.
I owe him so much.
You know,
he did so much for me.
He's like a saviour to me.
He really is.
(Enjoy the drinks. From Choi Sang Wook)
The DNA extracted from the cigarette butt you provided...
and the DNA from the blood found on the scarf...
were a match.
Gosh.
Kim Beom Joo.
You're dead meat.
Prosecutor Oh, it's Lee Jae Han.
I have the evidence.
Yes.
It will prove the murder that Chief Investigator Kim Beom Joo committed.
Yes.
That scarf...
It was the problem back then, and it still is now, right?
Who else knows about this?
I'll ask again.
Does anyone else...
know about this other than Prosecutor Oh?
Are you wondering how I found out when you only told Prosecutor Oh?
That's how the world is.
They're all on the same side. Didn't you know?
This is your last chance.
Give it up.
If you promise to give it all up, I'll stop here.
I don't want to kill a police either.
No.
You won't let me live anyway.
Do whatever you want.
Do it.
You mean you don't want to give up.
- Do it. - Okay.
Don't.
We just have to destroy the evidence.
The data's also in the States.
He can always ask for another report.
But...
this is just wrong.
He's a colleague.
Colleague?
Do you think he thinks of you as a colleague?
If you let him live, he'll ruin both of our lives.
Okay.
Chief. No. Please.
Are you insane?
You're the one who brought him here.
Chief. Please, don't.
Move!
- Get him! - No!
Don't!
Get a grip, you fool!
If he gets out alive,
you'll rot in jail for years...
for abduction and bribery.
Then your daughter will die.
Choose.
Is it Lee Jae Han or your daughter?
Choose!
Make sure Chi Soo finishes him off.
Okay.
It changed.
Park Hae Young, are you all right?
It changed.
We'll get there soon.
Just hold on.
The walkie-talkie...
It changed.
Last time,
when I first found it,
the person who told him not to go to Seonil Mental Hospital...
You told me about Seonil Mental Hospital, Lieutenant.
But this time,
the person who told him about Seonil Mental Hospital...
wasn't me.
It's August 3...
at Seonil Mental Hospital.
Don't go there.
Since we changed something,
the past might have changed, too.
When was the last time...
you saw Detective Lee Jae Han?
It was August 3.
He left to investigate Kim Yoon Jung Kidnapping Case.
It's the same as before.
Did anything change?
No...
I...
I think it'll be sorted out soon.
What?
Let's talk...
when this is all finished.
You're right.
I'll make sure to come back.
My last...
memory of him has changed.
I'll be right back.
My memory has changed.
I remember...
he only told me to wait until the weekend.
But now, I also remember him saying that...
it would be over soon and that he would be back.
The past...
has already changed.
The past...
has already changed.
If I die,
all the cases will end up cold.
Inju Gang Rape Case...
and Sun Woo's case, too. And...
Cha Soo Hyun.
You told me to wait!
So I waited for you for so long.
I'll go back.
We have a patient with cardiac arrest.
It was 11:23pm.
It was when the detective died.
More than the fear of death,
it was more unbearable for you to leave...
all those cases cold, right?
Did that desperation...
lead you to me?
Detective Lee,
please...
live on with that willpower.
Don't live on through a walkie-talkie,
but with your own will.
Don't give up.
(Each handcuff holds 2.5L of tears.)
Jae Han!
Hey, what took you so long?
The mobile location tracking isn't perfect.
- How did you know about this? - Kim Beom Joo...
Go find him right now!
Hang on. I'll call you an ambulance right away.
No, there's some place that I have to go.
- Hey. - Watch your head.
Jae Han!
What... What happened?
Are you crazy?
You told me to avoid criminals with knives.
But look at you.
How...
Let's go.
I... I kept my word.
I heard you were sick, so I came by.
I wanted to see you wake up,
but I have to get to work.
Don't skip any meals. From Mum.
The person who kidnapped Kim Yoon Jung last month...
was finally apprehended.
Ms Yoon, a nurse at a mental hospital,
kidnapped her to cover...
her credit card debts which amounted to 50,000 dollars.
She also killed Seo Hyung Joon, who was missing,
and has shocked the entire nation.
Sun Woo didn't do it.
What do you mean?
Did you say Sun Woo did nothing wrong?
Yes.
Sun Woo...
was not the assailant of the Inju case.
He...
was just trying to find the real culprit...
and got himself killed in the process.
Sun Woo...
wanted the whole family to live together under one roof.
That's why...
he got killed.
I am so sorry.
If only I had...
revealed who killed him or caught the Inju rapist earlier...
I'm sorry.
Sun Woo...
Officer.
Thank you.
Thank you so much.
All right.
Detective Lee Jae Han.
He's...
alive.
Welcome.
Do you have a broken watch?
Detective Lee Jae Han.
Do you know my son?
Yes. Well...
Where...
is he now?
I don't know how someone your age knows him.
But my son is missing.
He has been missing for over 15 years.
Hurry up and bring it over here.
What are you doing? Go on over.
Yes, Sir.
May I help you?
Hi. What happened here?
What's all this?
Which station are you from? Do you know me?
I'm Lieutenant Park Hae...
Who are you?
You don't belong here. Get out.
(Bukdaemun Patrol Division)
What on earth...
- Go ahead and escort him out. - Yes, Sir.
You shouldn't be here.
What a weirdo.
- Do you know him? - No.
Can't someone watch the door?
Where were we?
I told you that these two were different.
Where is it?
I gave it to you yesterday.
Then why isn't it here?
Maybe you misplaced it.
Gosh. Will you stop talking back to me?
Who are you?
Goodness.
Do they let just anyone waltz in here now?
You're Lieutenant Park Hae Young from Bukdaemun Patrol Division,
right?
Is this your desk?
Is...
Detective Cha Soo Hyun in?
Why do you need to see her?
Gosh. She always complains about having no money.
But she must have gotten another insurance.
Or did she buy a new car?
No, I'm...
Lieutenant Park Hae Young from Bukdaemun Patrol Division.
Lieutenant?
(Public Official ID)
You should have announced your name and title first.
Don't you know there were officials who were let go for not doing so?
I...
have an urgent matter to discuss.
Did she go far?
We don't know. She suddenly disappeared.
If you find her, let us know. Okay?
She's not picking up her phone and isn't home either.
Where did she go when things are hectic around here?
Anyway, send me the results again.
You're always like this. I won't do it this time.
You can't be losing things all the time.
I really didn't get it!
I print it for you, and you lose it.
Then I print it again, and you lose it again.
Do you collect waste paper?
I told you I didn't get it. Why would I lie about that?
(Police)
Why did you come to work on your day off?
What's the matter?
What are you looking for?
Where's the walkie-talkie?
The old one with no batteries... Do you remember?
What are you talking about?
I brought it here with me before.
Did you bring a walkie-talkie here?
I don't remember that.
Welcome.
- Now what? - We won't have any classes now.
- Coffee? - Two cups of coffee, please.
Okay.
Let's go eat something tasty later.
Sure, I'm hungry.
What should we eat?
There are a lot of famous places nearby.
Soo Hyun, hold on.
Cha Soo Hyun. Gosh.
Just wait, please.
Gosh. Hold on.
It's your first date. Are you going out dressed like that?
What's wrong?
Hey, they might need me at work while I'm there.
Should I wear a dress and heels?
But still, this isn't right.
Then, at least spray this.
Men love perfume.
- He'll be head over heels for you. - Forget it.
No, you have to wear it.
Let me have the room to myself before next year. Okay?
Good luck.
- Gosh. Go in. - Gosh.
It's better if I can have it to myself before tomorrow.
- Okay, then how about spaghetti? - Okay.
- Let's order pizza and pasta. - Sure. Sounds great.
I'll relieve my stress by eating.
That's right. It's a good idea.
Welcome.
Hey.
Let's go.
Go? Where?
Do you not like pork rinds?
No, I like them.
This looks delicious.
By the way, don't you smell something funny?
Is it this?
No, it's not.
Is this...
a place you come often?
No, not me.
But someone I know does.
Did you come to see the kid?
It's been a while since he last came.
He's living with his parents again.
Yes, I heard. I'll do it.
(Ripened Kimchi Pork Belly)
Who's the kid she's talking about?
You don't need to know.
It's not...
What?
Wait. You didn't...
No, right?
You punk.
Just drink.
Gosh.
Are you still running around looking for Kim Beom Joo?
You did your best.
Let someone else take care of him.
Kim Beom Joo is only a chess piece.
What do you mean?
There's someone else who should be punished.
It's someone who was behind all of these cases.
I have to right the real wrong,
so that I can change the past...
and the future, too.
Here. Have some more.
I don't think I've seen you with your hair down.
What? I had it down a few times at the office.
Gosh.
Why are you so dazed?
Goodness.
I can't believe that kid grew up and is now old enough to drink soju.
Time flies, indeed.
Was that the last time?
What?
The...
detective...
Yes.
He came here with a woman once, and I never saw him again.
Hello.
- Welcome. - Do you have pork rinds?
Yes. What kind of question is that at a pork rinds restaurant?
Gosh. It's so cold.
Detective Lee...
What...
on earth happened?
What?
Where did you say you are?
I'm sure it's Gyungjin-dong.
Inform the Police Squad and hurry over.
Jae Han!
Where in Gyungjin-dong is he talking about?
Get up.
I told you...
I'd make you pay.
So what?
Will arresting me...
change the world?
Being someone's dog...
is much better than complaining about how unfair the world is.
No.
Not you.
Arresting someone else will change the world.
I should arrest the uncle of the Inju case's assailant,
Congressman Jang Young Cheol.
He knew exactly what horrors his nephew had committed,
but to cover it up,
he killed an innocent boy.
He's that scum.
It was him, wasn't it?
So what?
That's how he got...
the power he has now.
That's how things work!
That's the problem.
It may have been once,
then a dozen times more...
He'll continue to commit the same crimes again.
Then he'll threaten some people,
pay others...
and tamper with evidence!
That's why I'm trying to stop him now.
I will make him pay for his crimes! Do you understand?
You?
The police,
the prosecutors...
and even the Blue House can't touch him.
As only a homicide detective, what do you think you can do?
The corruption behind Jinyang New Town Development...
The floppy disk...
you fiddled with before giving to the prosecutors...
You must have a copy.
Don't say you don't.
Someone as sly and dirty as you...
would be perfectly prepared.
Where is it?
Tell me!
- Kim Beom Joo! - Kim Beom Joo!
- There he is! - Stop there!
What a little rat!
"On November 20, 2000,"
"ex-Chief Investigator Kim Beom Joo..."
"was found dead in an abandoned warehouse in Gyungjin-dong."
"Considering multiple injuries all over his body,"
"he is suspected to have gotten murdered..."
"during a violent fight."
"Shortly before his death,"
"he met alone with Detective Lee Jae Han from Jinyang Station."
"A large amount of the suspect's DNA and blood were found at the scene."
"The key suspect, Lee Jae Han, has been missing..."
"since December 20, 2000."
"A little off Route 13,"
"the car owned by the suspect was found abandoned."
"Case closed due to the expiration of the statute of limitations."
Kim Beom Joo, who was suspected of corruption, was on the run,
was found dead in an abandoned warehouse.
Detective Lee Jae Han was wanted as the prime suspect,
but he went missing.
Detective Lee wouldn't have killed Kim Beom Joo,
who was a killer and also a witness.
Someone else killed Kim Beom Joo...
and framed Detective Lee.
But who?
Hey, you! Stop there!
Come over here!
Any news?
Jae Han.
Lee Jae Han!
Jae Han!
Where are you? Lee Jae Han!
Say something!
Lee Jae Han!
Jae Han!
Lee Jae Han!
If only I had the walkie-talkie...
If only there was the walkie-talkie...
Lieutenant Park.
Hey, get out!
How dare you?
Even if I don't have the walkie-talkie,
there might be a way.
Something's going to happen in Hongwon-dong for sure.
I saw it written down...
in your notebook.
In my notebook?
In the back of your notebook,
I found a piece of paper.
"South Gyeonggi Serial Killings in 1989"
"Luxury Home Break-In Case in 1995"
Are they written there? Are you sure about that?
Jae Han knew that...
I would find this paper in the future.
Hey, get out!
How dare you?
- Come on out! - Get out of there!
This is the last message that...
Detective Lee left me.
(1989 South Gyeonggi Serial Killings 1995 Luxury Home Break-In Case)
(1999 Inju Gang Rape Case 32-6 )
These are numbers that make sense...
to no one else but me.
(1989 South Gyeonggi Serial Killings 1995 Luxury Home Break-In Case)
(1999 Inju Gang Rape Case 32-6 )
(1989 South Gyeonggi Serial Killings 1995 Luxury Home Break-In Case)
(1999 Inju Gang Rape Case 32-6 )
Hae Young. What brings you here?
I went to see you yesterday.
How are you feeling?
Are you better?
Have some.
Look...
I have something I'd like to ask.
Do you remember the detective...
who solved Sun Woo's case when I was young?
Detective Lee Jae Han.
Did he leave...
anything here?
How did you know that?
The detective called me.
He said that he's going to send me something important by mail.
He told me not to tell anyone...
and to keep it until he comes back for it.
We owe him so much.
So I didn't throw it out and kept it until now,
thinking that he would come back one day to take it.
(Jeonghyun Medical Care Hospital)
(32-6, Yeonjin-dong, Yeonseo-gu, Inju City, Gyeonggi-do)
I'm not sure if you will get to read this letter.
But I really hope you do.
That's because this is the only way I can reach out to you.
Do you remember...
what you talked to me about during our first time on the radio?
The person who reached out first wasn't me. It was you.
Did you say I sent you a message first?
Yes.
You told me then...
that the transmission will start again.
You told me to persuade you back in 1989.
Lieutenant Park Hae Young.
Who are you?
- The person I talked to then... - Seonil Mental Hospital?
Was you when you didn't know who I was.
In the end, the messages between us...
must have gone in circles.
But after I came back alive,
I no longer got any messages.
I waited in the hopes of getting another message from you.
But maybe our link disconnected...
because I shouldn't have come out alive.
So until now, the walkie-talkie is still not working.
Officer.
Thank you.
Thank you so much.
That day, I thought...
such a thing might happen again...
if those who deserve punishment do not get punished.
The floppy disk attached...
contains the truth about the corruption...
behind Jinyang New Town Development in 1995.
I thought hard about whom and where I should send this to.
But...
I couldn't think of anyone...
that I could give it to in my time.
No matter whom I send it to,
I felt like the person receiving it would be put in danger,
or the evidence might disappear again.
The proof of the corruption behind Jinyang New Town Development...
is spreading quickly over the Internet and...
However, the world you live in will be different.
Your signature in the document on the Internet was confirmed.
Is it true that it was an internal document?
People are saying that you should step down from the board.
What are your thoughts?
Jinyang New Town Development was meant to solve...
the housing problem of our citizens...
and to develop the local economy. And it was a successful and...
innovative city development plan.
But to call such plan corrupted...
is an insult to the government who led the project...
as well as the citizens.
Let's go.
In order to settle the commotion, the Blue House is planning on...
implementing special prosecution.
If the investigation confirms that the rumour is true,
it'll bring a negative impact to Korean politics and business.
The document on the Internet...
is the very one that the detective,
who disappeared 16 years ago, took.
Do everything you can...
to find him.
Okay.
I believe...
that the world you live in will punish those...
who deserve it.
To me,
you, Lieutenant Park, who's in the future, are my last hope.
I guess this letter will be my last goodbye to you.
Please be well,
healthy...
and happy.
Hello.
Is this stamp from this post office?
Could you check who the sender was?
I'm looking for a missing person.
Could you please let me check...
any records of unidentified bodies or skeletons found in this area...
since November 24, 2000?
Why? Is it not there?
No.
I'm glad...
it's not here.
Have you ever seen this person around here?
Well... I'm not sure.
He's over 185cm.
If you ever see someone like him, please give me a call any time.
Sure.
Detective Cha...
Do you remember me?
When I woke up, our team had already disappeared,
and no one remembered me.
So I went all the way to Jinyang Station to find you,
but they said they couldn't get in touch with you.
But... But I still tried to find you...
But you couldn't find any number.
Was it the same for you?
Yes.
Like you said, everything had already changed.
When I woke up,
I went to the emergency room you were taken to.
But there was never a patient named Park Hae Young there.
I even went to your place.
Your mother...
told me that you were sleeping because you were sick.
I was glad.
What about Detective Lee Jae Han?
I remember...
everything.
I saw Jae Han's remains myself.
After things changed,
I don't remember doing that.
Jae Han is still missing.
And for the past 15 years,
I have been looking for him.
Something else changed.
It's a call.
After Jae Han disappeared,
I got a call.
This is Jinyang Police, Homicide Division One.
Speak...
Hello?
Jae Han?
Is it you?
It's you, Jae Han, isn't it?
Jae Han.
Hello?
This is Homicide Division One.
The phone number is 031-567-8236.
Trace the last incoming call to this number, please.
(033-652-8123, Sangin-gu, Junghyun City)
That person didn't say a word,
but it was him.
No, I mean...
I thought it would be him.
I don't know him.
Did that call...
come on November 24, 2000?
Yes.
On that day,
he sent me a letter from here.
It contained an important evidence.
The post office deletes their records every year,
so I couldn't check who sent it.
But I'm sure it was him.
It's this place.
Jae Han...
was somewhere nearby.
He was here 15 years ago but not anymore.
Why do you think he sent this to me 15 years ago?
He knew he was going to die.
So...
he wrote this letter to me...
hoping that...
I'd get the evidence.
- There's no proof that he's dead. - I also...
want him to be alive.
But...
he's not the kind of person...
who would hide for 15 years...
without contacting his father or colleagues.
If he was alive,
he would have...
reached out to us.
What if he couldn't for a reason?
What if he couldn't make any contact?
- If he was in a coma or... - Detective.
Nothing says that he's dead.
In other words, that means he could be alive.
(Junghyun Medical Care Hospital)
"Junghyun Medical Care Hospital"?
Why?
I got this text a few days ago.
I thought it was odd,
so I looked up all the hospitals with the same name in the country.
But I found nothing strange.
(Don't go to Junghyun Medical Care Hospital on February 5.)
That walkie-talkie...
Jae Han, you and me.
Only the three of us know about it.
August 3, Seonil Mental Hospital...
It's August 3...
at Seonil Mental Hospital.
Don't go to Seonil Mental Hospital.
Small hospitals...
accept people without identification.
It's possible to hide there for years.
It doesn't make sense.
He was wanted for murder for years.
How could he hide in a hospital...
for 15 years...
when he couldn't even use a credit card?
It's impossible...
unless he had someone's help.
Help...
There's no way...
he wouldn't have contacted anyone for 15 years.
Hello.
Do you have a broken watch?
Detective Lee Jae Han.
Do you know my son?
(Gangwon to Seoul)
It never...
made sense from the beginning...
when the messages came...
through the battery less walkie-talkie.
So there's no need to be disappointed already.
(Junghyun Medical Care Hospital)
No one knows what's at the end of this road.
I could meet my closest friend...
whom I have never met before.
Or...
we could be welcomed by an unexpected threat.
We can't be sure of anything.
If...
Jae Han was the one who sent this text,
going there would be dangerous. You should know that.
He was killed...
when he went to Seonil Mental Hospital on August 3.
He always kept his walkie-talkie with him.
We lost touch,
but he could have gotten through to someone else.
Like before,
he reached someone from the future,
and that person...
could have warned him that...
something would happen at Junghyun Medical Care Hospital...
on February 5.
No. It could be the opposite.
He still went to the hospital even after hearing that.
If he thought that we would go there as well,
that could be the reason why he sent us the message.
Hey.
What are you doing?
There is only one thing we're sure of.
The transmission started out of one man's desperation.
One thing that voice over the walkie-talkie...
has taught me was...
that things work out if I don't give up.
Is it the same over there, too?
Can the rich...
and powerful...
do whatever they want and never be punished for it?
But 20 years has passed.
Something must have changed.
If they commit a crime,
we must make them pay for it...
even if they are rich and powerful!
That's our duty as police!
I won't give up.
I'll go all the way, no matter what.
A detective...
shouldn't be distracted.
I have to right the real wrong,
so that I can change the past...
and the future, too.
If we don't give up,
we can break down the authority that seemed unbreakable...
and find the person we searched for 16 years.
It's all possible.
If we don't give up,
there is hope.
