(and surroundings in this drama are fictitious.)
(The scene was filmed while tending...)
(the mental state of the child actor in this episode.)
(We promise to follow up with counseling and needed treatments.)
Okay, we're here.
Our backup will arrive soon.
Su Young and I will go that way.
We'll go this way.
(Episode 8: Variable, A number that can...)
(always change depending on the change of conditions)
Team Leader Hwang. Right here.
Yu Bin!
Where did you go?
We must go home.
If you're apart from Mom,
bad people might come for you.
You must stay close to Mom.
That way, Mom can protect you.
Yu Bin.
Someone was here until a while ago.
I think Hyun Soo tried to call Su Young from here.
Team Leader Hwang, these look like sleeping pills.
Even a small amount is lethal to a child.
Team Leader Hwang.
What is this?
We must find Hyun Soo fast.
Yu Bin!
Yu Bin.
You can't play here.
You got lost last time while playing here!
Yu Bin.
You really won't come out?
Yu Bin.
Where were you?
Mom looked for you for a long time.
Let's go home now.
You go this way.
You can't let Mom down now.
I was so nice to you.
Stay with Mom, okay?
Mom will plead, like this.
You are Yu Bin.
You are my son Yu Bin.
Mom can do anything you want.
For you, Yu Bin, Mom can really do anything.
Come with Mom, okay?
He's not here.
Where are you?
Hyun Jae. Hyun Jae. Hyun Jae!
I Su.
Hyun Soo!
I found Hyun Soo.
It's the rooftop of the building.
Hyun Soo. Hyun Soo.
Are you okay?
I'm here. You're going to be okay.
Are you hurt?
Kim Na Hee.
My son.
Give him back.
I beg of you.
Kim Na Hee.
I know you're looking for Yu Bin.
That's why you saved Hyun Soo from his kidnapper, didn't you?
The boy I saved is Yu Bin.
Thanks to you, Hyun Soo is alive.
But you must stop there.
Get away from my son!
I will make you pay for this!
Let go.
You must stop.
Stop what?
Your son died five years ago.
Admit it.
What are you saying?
My Yu Bin is right here.
That boy is Hyun Soo.
It's time you escape from your delusion.
No! No!
You're all lying!
- Don't lie! - No!
It's time to be honest.
You knew all along.
Didn't you?
Yu Bin...
My Yu Bin's right there.
Look at my Yu Bin.
My Yu Bin's right here.
Will someone get him out?
Give my son back.
You see him.
Don't you see Yu Bin?
Yes.
I see him.
Look carefully.
He can't leave his suffering mom.
Because you're so lonely.
Because you're struggling.
Will you leave him like that?
It's time to let him go.
Tell him that Mom's okay.
That you can start over.
Only then can he leave in peace.
Let him go.
Kim Na Hee.
You're under arrest for...
abduction, No Sang Chul's murder, and abandoning the corpse.
Let's go.
I'm sorry. I took my time.
(No.)
(I believed you would come.)
I believed that you would get through it.
Man Su.
Why do I feel so bad?
You do? My gosh.
I feel bad for myself. I can't even go home.
(This is a secret.)
What is it?
(I saw Yu Bin in there.)
(I was mistaken, wasn't I?)
I bet Yu Bin looked after you.
(911 Rescue)
What are you thinking?
How much torture can someone's pain inflict on them?
The snow globe in Kim Na Hee's office.
Yu Bin's ashes were inside.
She remained in the past.
Kim Na Hee...
seemed to believe that Yu Bin was still alive.
Hyun Soo said he saw Yu Bin inside.
I Su.
Everyone has a scar.
I think the mirror showed that.
Thank you.
For helping me find Hyun Soo.
If you still need me,
I'll accept the offer you made.
Good job.
(57 hours after the abduction, Case closed)
(Tell Me What You Saw)
(Mucheon Metropolitan Police)
The victim, Gil Hyun Soo, was admitted to hospital...
for psychological care.
Fortunately, his doctor said...
he will make a full recovery after a few days of rest.
The police never once, not even for one moment,
gave up hope that we'd find Hyun Soo alive.
Thank you.
The bear jumps tricks while the master gets paid.
You be the master then.
Right?
I thought I'd get to see you at the station.
I apologize.
You did well. You saved the young boy.
It was fortunate.
Things got a bit messy after you resurfaced.
I told them to let it go quietly.
The world doesn't know about our ties, Commissioner General.
The world...
doesn't know about me and I Su's ties.
When my friend died,
I think I Su was in high school.
I swore in front of my friend's photo.
"I will keep a close eye on your daughter for you."
Don't worry about anything and return to work.
The RIU needed a new profiler anyway.
(5 years ago)
We're looking for a duo. This was an execution.
They went about slicing and dicing with a Chinese kitchen knife.
The victims tried to run away and got their throats cut...
and legs chopped off as they died.
And this victim here.
He managed to stay alive for a long time.
Listen carefully.
We must think from the attacker's perspective.
With their logic. Their point of view.
You're home?
How was today's case?
Today, I saw a lot of bodies.
Give me a moment.
You can't just call them bodies.
They were someone's son, daughter, or family.
It's hard, isn't it?
You did well.
Let's rest now.
So, did you decide to return?
When I went to Sim Gyeong Su's place.
I found a trace that someone was listening in.
If someone was controlling Sim Gyeong Su...
He would be The Guy.
So?
I must start over.
With myself exposed.
As a member of our team?
Yes.
In the RIU.
(Mucheon Metropolitan Police)
(Oh Hyun Jae, Assigned as profiler)
(Mucheon Metropolitan Police, RIU Team One)
(Mucheon Metropolitan Police)
(Senior Superintendent Choi Hyung Pil)
When someone high up let it go,
we should've noticed then.
Oh Hyun Jae was staying at a safe-house.
I had no idea the Commissioner General had ties with...
Oh Hyun Jae's fiancee.
At least we know now.
We're on the same side, aren't we?
Of course we are. I don't suspect you.
Because you have a lot to lose.
Why is this so heavy? Gosh, it's killing me.
Are you sure this room's bigger than that room?
- It's the same size. - Get out of the way.
Think about it. I have my own toilet,
and there's a window. It's home sweet home.
You told your dad you're staying in a studio apartment.
I came here to help you move your things.
What should I tell him now?
Isn't it obvious? Do what you do best.
Awkward sign language.
You can be so mean.
It's a suite.
Hi.
Boyfriends aren't allowed.
He's not my boyfriend.
The manager's weird and so is your room.
(Victim Lee Choon Eop, Witness Eun Ji Sung)
My gosh.
Leave my things here.
You think I don't know you came here for your mom?
You're quick to notice.
Did you do some research?
I see you have some notes.
Did you get anywhere?
Not yet.
You'll find the hit-and-run driver.
I bet the scumbag's living a great life somewhere.
Be strong, Cha Su Young.
Be strong.
Su Young,
when should we get jjajangmyeon?
What makes you think we deserve jjajangmyeon?
What makes me think so?
Right, we've done nothing. I'll head back now.
Fine, let's get tangsuyuk as well.
Nice!
(Mucheon Metropolitan Police)
(Hyun Jae's Return, Agree or Disagree)
I disagree. What about you?
Is this necessary?
- I'm down. - Say that you disagree.
What about you?
Why do you disagree?
Man Su. Listen to me.
You've been the second-most powerful person on Team One, yes?
What do you think will happen if Detective Oh comes back?
You know well what'll happen. Why are you so dumb?
- I disagree... - Right?
That's not...
what I'm saying.
But your voice was trembling just now.
- It was trembling. - Wait,
Detective Oh is coming back? To where?
I see you've heard nothing...
since you asked for days off for moving.
Detective Oh!
Be quiet.
He's returning as of yesterday...
and rumors say that he's coming to RIU Team One.
- Really? - You think I'd be lying?
(Chinatown in Haewol-dong)
What do you think you're doing?
Hey.
The victim is the number two of the Sinwol Gang, Chu Won Pyeong.
Who was the first to find him?
The guard found him.
Anything odd?
He still has all the money he collected from others,
so it seems like it was a revenge murder.
It hasn't been long since he became number two of the group,
but why do I feel like he's going to have a long story behind?
I think it's a revenge crime between gangs.
It's going to be quite a case.
Which is probably why the local police called the RIU.
Something is off. Murderers usually don't leave the body out like this.
Look around and remember. The first glance is the key.
Yes, ma'am.
It's as if someone played a claw machine game for him.
Where's Detective Oh?
He's skipping already and it's only his first week back.
The rumors were true that he's not a team player.
You can ask Team Leader Hwang yourself.
Shouldn't he report his return to us...
and greet each of us politely?
Su Young, he talked to you, didn't he?
He's on his way.
- My goodness! - What is it?
Look at him!
He's injured.
No!
My goodness!
Hello?
Are you all right?
What do we do?
My goodness.
Look at him.
I think he's dead.
He just collapsed.
This is terrifying.
Team Leader Hwang!
He's dead.
This is terrifying.
He's dead.
This is the second murder case of the night.
He just bled to death. There aren't any other damages.
That's the exact same way...
that Chu Won Pyeong got killed.
It's poison in the blood vessel.
He's bleeding from every hole in his body.
The two victims have the same shot behind their left ears.
He must be a Sinwol Gang member as well.
This is horrifying.
He's really dead!
Come here!
Stop running!
What an annoying little rat.
Where did he go?
That way!
- Look around carefully. - Where did he go?
Are we going to stay up all night looking for him?
Find him quick!
Darn it.
Have you not found him yet?
No, sir.
I told you, get him and bring him here quick.
Yes, sir.
We have to find him before the police do.
Yes, sir.
(Mucheon Metropolitan Police)
(Guwol Gang)
The murders seem to be from a fight between...
the Guwol Gang and Sinwol Gang regarding their properties.
Chu Won Pyeong and Kim Pan Geun are both Sinwol.
They both died from excessive bleeding.
- What made them bleed? - Crotalotoxin...
which comes from viper snakes.
Look into all dealers, delivery routes, and buyers.
- Yes, ma'am. - Any suspect?
The strongest suspect is...
Ha Tae Sik, the head of Guwol Gang.
Sinwol Gang has been expanding their territories violently,
and it seems that Tae Sik committed the crime...
because he was threatened by their expansion.
Gangsters these days don't kill people out in the open like this.
It gets people talking and interrupts their businesses.
Tae Sik's car was photographed...
nearby the site of the first murder around the time of death.
The second murder case also took place in his territory.
That's circumstantial evidence,
- and anything else? - We're looking into it.
The only links that we found between the two cases are...
that they involved poisoning and Tae Sik.
There's a big chance that Tae Sik may flee.
Put him on the wanted list.
Ji Min, request for an arrest warrant.
Will do.
Ji Min, where's Su Young?
I hear she's on site with Detective Oh.
But this is a team meeting we just had.
The rumors were right.
He has no sense of teamwork.
Look at him, he's acting on his own as soon as he's back.
Stop complaining and get ready to go out.
You complain a lot.
Seems like we won't be going home anytime soon.
Where are we going?
We're almost there.
(Great Detective Cho)
(Welcome, your secret is safe here with us!)
- What brings you here? - Cho Bak Man is here, right?
What? Cho Bak Man?
How dare you call my boss like that?
My, my.
Long time no see.
I heard...
that you're back on the team.
What brings you here?
Won Pyeong and Pan Geun died...
here in Haewol-dong last night.
Tell me everything you know.
Won Pyeong and Pan Geun were...
formerly a part of the Guwol Gang,
then they betrayed them and joined the Sinwol Gang.
Let's work hard. Cheers.
It's been a while since they left the gang.
So what?
I don't know.
But it's a little odd.
Fights between gangs usually are really loud,
but it's been too quiet.
What did Tae Sik say?
He's been quiet ever since...
he got all his members snatched away.
Who's that beside you?
- Me? - Yes.
- I'm a detective. - What?
- Bak Man, if you see...
anyone suspicious here in Haewol-dong,
contact Detective Cha right here.
Really?
You have to respect that I'm a man too.
Of course I'll contact you,
yes.
Detective Lee Ji Min of RIU Team One speaking.
What? Come clean?
Apparently, Tae Sik is on his way here to come clean.
- Who? - Tae Sik.
He's on his way.
What?
- What's up? - Tae Sik is...
on his way to come clean.
Right now?
(Mucheon Metropolitan Police)
Look!
Isn't that Ha Tae Sik?
He's here.
(Mucheon Metropolitan Police)
I killed them.
Tae Sik.
You realize that murdering two men...
and disposing their corpses result in a heavy sentence, right?
We're arresting you...
without a warrant on February 27 at 11am today.
You can explain yourself...
and have the right to hire a lawyer.
You have the right to refuse to answer our questions.
Let's go.
What?
Tae Sik came clean?
All right.
Tae Sik.
What are you thinking?
Born on January 19, 1968.
You're Ha Tae Sik, yes?
Tae Sik,
you've been arrested for murdering Won Pyeong and Pan Geun.
You have the right to refuse to respond to unfair questions...
and to hire a lawyer.
Tae Sik,
where were you on February 26, 2020...
between 9pm and 12am?
Here.
This is your car, right?
It was caught on camera near the site of the murder.
Why did you kill them?
Do you admit to killing them?
You're laughing? You think this is funny?
I don't think you know where you are right now.
Do you want me to show you?
Calm down.
I'll take over.
Man Su. Let's head out.
He's laughing.
Let's go.
The way he laughs is so unpleasant.
Why is he being like this when he walked in here himself?
This isn't the Prosecutor's Office.
Any confessions made during a police investigation...
can always be retrieved.
And confessions by themselves have no legal power, either.
We need to issue the arrest warrant within 48 hours then.
Chief Choi, what brings you here?
Did you get anything?
He hasn't said anything yet.
Tae Sik.
If you aren't going to say anything, why did you come in the first place?
I'll talk.
Get me Oh Hyun Jae.
What?
He aimed for the artery within a single shot.
It's the easiest way to kill someone,
yet the cruelest way of doing so.
The poisoned dies slowly...
and can feel the poison slowly spreading through their body.
He must've watched that happen from over there.
Why do you think he was so cruel to kill them this way?
It's a mix of...
staging, showing off the crime,
and taking revenge.
It's me.
I heard Ha Tae Sik...
will only talk to Oh Hyun Jae. What will you do?
He walked in here on his own and turned himself in.
What choice do I have?
If he talks,
it's over for both of us.
A sword can be frightening when it's kept inside a sheath.
I doubt he'll talk about that incident.
Is there evidence that he's the killer?
There's circumstantial evidence,
but it's not crucial.
I'll talk to my people in the prosecution.
Transfer him over now.
Why did Ha Tae Sik turn himself in?
I wouldn't be here if I knew.
He will only talk to you, Hyun Jae.
Does anything ring a bell?
I want his statement.
It's been a while.
Why did you ask for me?
You'll probably end up catching me.
I guess you could say...
that I wanted an old friend of mine to interrogate me.
A friend?
Sure. There are three types of friends.
A friend who likes me, a friend who hates me,
and a friend who doesn't care about me.
I like the second type.
You teach me to be careful.
Hey, Ha Tae Sik. You know what?
If you're trying to stall time and walk out of here a free man,
you will regret...
that you walked in here on your own.
All right.
What do you want to know?
You wanted to catch me.
What are you hiding?
If you figure that out,
I'll tell you what you wanted to know.
Ha Tae Sik is not an easy match.
He was indicted 17 times.
But he was acquitted every time due to the lack of evidence.
Why does Ha Tae Sik want to talk to Detective Oh?
That's our job to find out.
- What about the evidence? - Not yet.
We're still waiting on the autopsy result.
He turned himself in, but if we can't find any evidence,
we can't prove that he's guilty.
We must find the evidence.
I must raid Ha Tae Sik's office once again.
There must be something the Forensics missed.
They turned the place upside down.
What do we need to find?
Ha Tae Sik's purpose.
Come upstairs.
Ha Tae Sik, that jerk, is a sly and efficient criminal.
I'm sure he made a way to get out of this mess again.
We should make that useless.
Su Young, come with me.
Did you want to see me?
Report to me what Oh Hyun Jae and Ha Tae Sik are talking about.
Don't leave anything out.
Yes, sir.
Ji Min.
Don't forget who helped you become a cop...
and get this far in your career.
Okay?
Yes, sir.
Where did he go?
- Where did that rat go? - Darn it.
He's not here.
Where on earth did he go?
Hey, search every nook and corner!
- Yes, sir. - Yes, sir.
Hey, let's go!
Gosh, Ha Tae Sik.
What did we miss?
(L)
Team Leader Hwang.
- What is it? - I see something inside here.
"Crotalotoxin"?
It's the same poison used to kill Chu Won Pyeong and Kim Pan Geun.
We found the evidence.
We'll stop by the NFS and head over there right away.
(Mucheon Metropolitan Police)
You're back.
Su Young, go inside and switch with him.
Yes, ma'am.
Did you find evidence that I'm the culprit?
In the fish tank.
I killed them.
They betrayed me. I had to make them pay.
Hey, Tae Sik. This isn't how you handle things.
Why are you trying to give us the evidence on purpose?
Yes, this is the almighty Hyun Jae.
The murder weapon used to kill Chu Won Pyeong and Kim Pan Geun,
the fingerprints and footprints found at the scene...
are pretty straightforward.
Any detective would have found them. It didn't have to be me.
I knew you'd catch me in the end.
I wanted a competent detective to arrest me.
Why are you forcing yourself to be the culprit?
Why are you saying that I'm not the culprit?
You have the evidence.
Isn't this funny?
I'm claiming that I'm the culprit.
But you're telling me that I'm not.
What's going on? Why does he keep checking out the tumbler?
You know what?
The evidence you're showing to me and your confession.
I'm not buying any of it.
Let's...
call it a day today.
I have human rights too.
What should we do?
Send him to the holding cell.
- Well done. - My gosh.
Well, we have the evidence and he confessed too.
Let's transfer him to the prosecution...
once we get the autopsy result from the NFS.
There are still variables.
Variables?
The poison won't be enough to put him away.
The same goes for his motive and circumstantial evidence.
He can recant his confession any time...
by arguing that he was coerced.
Ha Tae Sik is hiding something.
We must find what he's hiding first.
Well, earlier, Ha Tae Sik...
was looking at the clock, reflected on the tumbler.
My gosh, why are you talking about that?
The clock?
He was stalling time.
Ha Tae Sik didn't want...
Hyun Jae to be at the crime scene.
Is that enough to turn himself in?
A crucial piece of evidence...
is the people.
(Mucheon Metropolitan Police)
- This is Cha Su Young. - Detective Cha.
I've been using all of our resources to find out.
And I got a big one for you.
Cho Bak Man? What did you get?
I heard that Sinwol Gang is going crazy, trying to find someone.
Well, I don't know whom they are looking for though.
Okay. Thank you.
Sinwol Gang is looking for someone now.
How do you know that?
Well, I have an informant.
How could you have an informant?
Sinwol Gang is looking for someone?
It's a witness. There was a witness at the murder scene.
A witness?
Ha Tae Sik has been stalling time here...
while his gang looked for the witness.
But why is Sinwol Gang looking for the witness?
- Why not Guwol Gang? - We must find the witness first.
Starting now, we'll surveil Sinwol Gang for the remaining hours.
- Yes, ma'am. - Yes, ma'am.
(We couldn't find him.)
(Interrogation Room)
My goodness. This is awful.
Team Leader Hwang, the NFS just faxed us something.
- Give it to Hyun Jae. - Okay.
(Evidence)
Hey.
When Chu Won Pyeong was being murdered,
he left a dying message.
It's a button that fell from your jacket you're wearing now.
A button.
I was wondering where it had gone.
It was inside that jerk's stomach.
It was inside his stomach?
Inside his stomach.
I didn't tell you that it was in his stomach.
The button was found in his throat.
That means there is a possibility that someone tried...
to shove it down his throat after Chu Won Pyeong died.
(National Forensic Service)
Why do you think he did that?
I mean, why did you do it?
I killed him.
Okay?
Detective Oh, a word, please.
(Senior Superintendent Choi Hyung Pil)
You're here.
Take a seat.
How does it feel to be back?
Why did you ask to see me?
Am I not allowed to call on my junior detective?
All right. How's Ha Tae Sik's interrogation going?
You already know everything.
Ha Tae Sik is like a sly snake.
He already confessed, so hand him over now.
The higher-ups are very interested in this case too.
I don't think they are comfortable with this case.
Who's causing this discomfort?
Is it because of Ha Tae Sik?
Or...
is it me?
A competent detective got reinstated.
Why would they be uncomfortable?
Tell me the real reason why you came back to work.
To protect people's lives and assets,
to ensure public safety, and so on.
Let's say those are my reasons.
If that's all, I'll get going now.
Hyun Jae.
Are you still living in the past?
I'm out of it.
I have a job to do.
Excuse me.
Where are we to find the rat?
Hey, you. Stop right there.
Hey.
- Get him! - Stop! You jerk!
Stop where you are!
Hey! Stop running!
Come here!
- You two, go that way. - Okay!
Stop running!
Hey, you. Come back here!
- We got you. - My gosh.
Hey, hey. Come back here.
- Come here. - We got you.
Did you think we wouldn't get you?
Boss, we found him. We'll bring him in.
Hey, hey, you can't do that.
Don't do that. Stop, stop.
My stomach hurts.
Who are you?
Did you join recently?
You don't know me? That's unbelievable.
Spit out your gum.
- Get them! - Darn you.
Stay still.
That hurts.
No, no. I'm with the police.
Are you okay?
I saw it.
The murder.
What?
Okay.
Well done.
We have the witness.
(Epilogue)
In that case,
why did you need 48 hours?
Tell me.
Everyone...
has a secret they want to hide.
What is that secret?
Five years ago,
at Junggeon Three-way Intersection.
There's a secret.
What could that secret be?
♫ Won't you tell me now ♫
♫ This game won't gonna get you out ♫
♫ Won't get you out ♫
♫ Silence won't tell you ♫
(Tell Me What You Saw)
Are you sure it's not him?
It wasn't him.
Please find him.
He turned himself in,
provided an alibi, and now wants to be let go?
He got us good.
Why on earth did he need 48 hours?
Who's the man...
with the motorcycle helmet that he mentioned?
It's a truth we didn't see. What we almost missed.
Not all truths can be seen.
If not all what we see is true,
then what must I see?
♫ Silence won't tell you what to do for you ♫
