(All characters, organizations, places, and happenings...)
(in this drama are all fake and are not based on a true story.)
I can foresee the future.
For the first and last time in your life,
you'll have to kill an innocent person today.
That man told me...
that I'd have to make a difficult choice.
And I've already made my choice.
Why did you...
- kill Ji Soo? - I did it...
because of the Principle of Causality.
If you decide...
to dirty your hands with that one death,
you'll save dozens...
No, you'll save hundreds of lives.
(Episode 7)
Hey, Si Joon.
Where are you now?
I'm sorry.
I know I said I'd stay at the office, but I broke my promise.
Si Hyun, wait for us there.
We'll meet you in a bit.
We just got the address from Lieutenant Oh too.
- If we leave now... - It'll take at least two hours.
By then, the situation will already be over.
Your life is on the line.
To me, nothing else matters more than your life.
The sketch won't change.
Si Joon, if this is my fate,
I should just accept it.
- Si Hyun. - Goodbye.
And let Captain Moon know that I'm...
grateful for everything he did for me.
Wait, Si Hyun.
You two must be happy to see each other.
Say hi.
All right. Now that all the actors are here,
we should get started.
A former sergeant first class...
who lost his wife when she was pregnant.
And the cop whose fiancee was killed by him.
The two enemies have finally met like this.
I guess anyone can predict the outcome of this encounter.
A bloody battle for revenge.
Bang.
Do you want to slash a ligament?
There.
The fierce battle between the two men...
is about to reach a climax.
To be continued.
Shall I cut off one of his arms? Like this.
Don't kill me.
Are you scared?
In the end, what was found on the scene was...
Detective Kang Dong Soo who was stabbed to death and...
Bang.
The former sergeant first class,
Kim Do Jin, with a bullet hole in his head.
Then they pass over to the other side hand in hand.
What do you think?
Isn't it a pretty good plot?
By the way,
why do you seem...
so relaxed, Sergeant Kim?
I have a gun, and yet you choose to irk me.
I'm grateful.
You're grateful?
For what?
There are people...
who are better off dying,
and you taught me that.
Is this fun for you, Sergeant Kim?
All right.
Fine.
Let's see if you can smile even after...
a bullet pierces through your head.
- Wait. - Goodness.
Goodness, you surprised me.
I thought that you were...
not afraid of dying at all.
You totally got me there.
So? You said, "Wait." What now?
Are you going to apologize?
Will you beg for your life?
My gosh, this is getting interesting.
What time is it now?
Do you want to leave a will?
It's 8:58pm.
Inside that fridge over there,
you'll find a bag.
Inside that bag, there's something that will take you by surprise.
It's my gift for you.
It's too detailed for a lie.
Why don't you find out for yourself?
It's right there.
What's that?
Who put it in there?
I told you.
It's my gift for you.
Stop spewing total nonsense.
I decided only an hour ago to move you here.
How on earth could you have put that in there in advance?
There's someone...
who knew it'd happen.
Take this.
It'll be critical in the mission.
What are you talking about?
Are you saying you knew in advance...
that you'd be held hostage here right now?
Do you actually expect me to buy that lie?
What do you think I put in that bag?
Stay away. Stay away!
Why don't you try to win me over...
with that money you worship?
I will...
scrap Cadinox.
I'll cancel it completely.
I...
will resign as CEO of Sunwoo Medical.
I won't make any drugs for a while!
Okay? I promise.
Don't worry.
You won't be able to make or sell any drug...
from today on.
The death of certain people benefits the world...
more than their lives do?
Do you think you're the guardian of justice or something?
Are you saying...
you killed Ji Soo...
in order to continue that idiotic hero game?
I'm sure...
I'll pay for my sins one day as well.
I'm prepared.
That day...
is today.
Stop! Stop it.
Detective. I'm not here to help you get revenge.
If you move, I will shoot.
Shoot if you want. I won't stop.
Let go.
Let go!
Kim Do Jin!
You're not going anywhere.
You stupid wench.
Do you have any idea who I am? Die, you wench!
Si Hyun!
Wake up.
Detective Kang Dong Soo!
Wait up.
Si Hyun.
Corporal Yoo.
My sketch was wrong.
Why did Kim Do Jin...
save you?
Tell me.
There must be a reason why he saved you.
I don't know.
I really don't know.
Si Hyun!
Are you okay?
I'm so glad...
that you survived,
but this is the first time...
your sketch turned out to be wrong.
What kind of variable do you think effected your sketch?
I can only think of...
one possibility.
It means there's someone else who can foresee the future.
On top of that, it's someone who has stronger powers than I do.
Even if that's the case,
I don't understand how that person could change your sketch.
Well...
If that person...
has the ability to foresee...
the sketches...
that I draw,
then that person would also be able to change my sketches.
Then...
are you saying Kim Do Jin has that kind of power?
I decided only an hour ago to move you here.
How on earth could you have put that in there in advance?
There's someone...
who knew it'd happen.
Kim Do Jin...
has someone helping him out.
Can you fully trust me now?
Jung Il Soo and Nam Sun Woo.
You were right about everything.
What's important is that you've fallen into a trap.
We have a change of plans.
I want you to move Kim Do Jin to Jinpyeong River.
Move him right now!
I decided only an hour ago to move you here.
How on earth could you have put that in there in advance?
However, there's one thing...
I don't understand.
That cop named Yoo Si Hyun...
I know she's a good cop.
And she also seemed like a pretty decent person.
But...
it's also true that she can get in our way.
- That's a possibility. - I'm fine with your orders.
However,
I just don't get why you had to go through...
such a complicated process just to save her life.
That's because Corporal Yoo...
is a very precious person.
(Rest in peace, From Joongki Police Station)
Why did you do that?
- Pardon? - I'm talking about...
when Nam Sun Woo tried to shoot me.
You could've died.
Okay, fine.
If that ever happens again,
I'll make sure I hide behind your back. So...
You're a lot like Ji Soo.
Ji Soo use to be like that too.
If she believed something was right,
she just went forward with it...
without giving it much thought.
But in the end,
the ones who get left behind are the ones who have to deal with the pain.
One day, you also might end up hurting the people around you.
They'll grieve and be in pain...
just because they loved and cared about you.
And that will last a long time.
Think about that the next time you decide to...
throw yourself in front of a gun.
Then what about you?
Why aren't you thinking about how Prosecutor Min might feel?
You're ruining your life...
just for the sake of getting revenge.
Do you really think...
you have the right to say that to me?
You're right.
Pardon?
You're right.
I have no right to tell you...
what to do.
I apologize.
I'll join your team.
Kim Do Jin and the guy who's behind him...
Well, let's call him "X" for now.
Anyway, Corporal Yoo...
won't be able to deal with the two of them all by herself.
And I'm guessing you're doing this to get revenge?
I won't deny the fact...
that I need Corporal Yoo's talent in order to find Kim Do Jin.
But as long as I'm a member of your team,
I'll make sure I don't cross any lines as a cop.
And how am I supposed to believe you?
You're the man in charge.
You can always fire me whenever you want.
Do you think it'll be okay?
He's like a ticking time bomb that can explode unexpectedly.
It might be better for us to keep him close by.
I have to say, Detective Kang really does have a strong heart.
The funeral got delayed because of the autopsy,
but he tries so hard not to show how heartbroken he is.
He can be really annoying sometimes,
but he seems pretty decent at times like this.
We already cleared out all of Prosecutor Min's stuff,
but then we found this scarf.
(Baek Woo Jin)
When did she start?
It's been about 40 minutes.
She's on her fifth page now.
Were there any sketches with Kim Do Jin?
That's what interests you the most, right?
Sorry, but not this time.
It's another violent crime.
It won't be easy this time either.
Chief Jang Tae Joon.
(ID, Password)
(Mo Wool Gyo)
We have to find out the identity of the man...
trying to kill Chief Jang first.
Is there anyone who may have a grudge against him?
A grudge.
When you consider how he works,
if you tell me to make a list of people who may have grudges,
I'll have to give out numbers and line them up.
About that first sketch.
Do you think that's a code of some sort?
I don't think it's that complicated.
Look at it simply. That's an online log-in page.
The text inside is the ID.
The ratio of the login window is 8 to 1.
There are those marks, too.
And these are the websites...
that people use most, in order.
I printed from 1 to 50, so I'll scan them...
from the top down. Si Hyun, you scan them from the bottom up.
Okay.
Detective Kang, you can start in the middle.
I'm going to figure out the location of that building and check it out.
I may find something there.
Hey, Detective Kang! You can't just do...
Okay. I'll go see Chief Jang.
He may know that guy in the sketch.
Work hard.
See you later.
If you came to see me voluntarily,
it must be serious.
I need to ask you something.
You always get straight to it.
Do you know this man in the sketch?
I don't know. He isn't triggering any memories.
It's important. Take a close look.
It's important? How important is it?
Let's say, your life is on the line.
This looks like just a portion of the sketch.
May I see the rest?
You and some others at Police Headquarters...
may believe in Corporal Yoo Si Hyun's sketches,
but I don't.
Don't take this lightly.
Your life is at stake.
Of course, I'll take your warning seriously.
How much should I compensate you?
I appreciate your coming all the way here,
but I'll protect myself.
I'm not like you.
I will not leave my fate to a piece of drawing like that.
Be careful for the next...
three days.
(ID, Password)
There's nothing.
What about you?
I found nothing too.
You check from 501 on.
I'll go from 1,000.
Did you find anything?
Not yet. What about you? Did you find anything?
Not really. Nothing much.
The senior members worked hard in the office all day,
and the new member who just joined goes out to do a survey,
and all he did was take a walk.
What manners is that? How did you come back alone?
Coffee?
Coffee's good.
But Si Hyun, we haven't had lunch yet, right?
No.
I guess we had a lot of work, if we even skipped lunch.
We're hungry, but there's nothing to eat.
But we can't drink coffee on an empty stomach.
I'll just keep working.
Well... Seeing how considerate you're being...
Thanks.
Let's eat.
Eat slowly. You'll get sick.
It's super sweet. It melts in your mouth.
Are you okay?
- Lieutenant Oh. - Yes?
Hold on.
What?
(ID, Password)
Si Hyun, your sketches are really fascinating.
Now, we just need to figure out the password.
Lieutenant Oh, three minutes should be enough for you, right?
That's how long it takes for cup noodles to be cooked.
When I set my mind to it,
it's a piece of cake for me...
to break into the Ministry of National Defense's server.
My goodness.
I'm already logged in.
But I don't see any log-in history from the last few years.
I don't think anyone uses this account anymore.
What was the most recent activity?
The last upload I see here...
was about four years ago.
It's a video file.
Sir.
I have a boyfriend.
So what? I have a wife too.
I'm just saying we should have a little bit of fun.
Goodness.
Well...
Fine, you can leave if you absolutely hate the idea.
It's no fun to spend time with a woman who doesn't like me.
But you see,
don't you think you have a lot more to gain from just doing it once?
I never do it twice with the same woman.
Sir.
Think about how hard you had to study to get this far.
Eun Jin, you need to become a good teacher.
You should make your parents proud.
Will you take your clothes off?
Or shall I undress you?
The flickering image
In the midst of the fog
I thought I could catch it, but it's getting far away from me
The street that reminds me of the rainbow
Are you waiting for me on that street?
I look around
But I don't see you anywhere
It's my favorite song.
I guess it's my lucky day today.
I still can't believe that a 25-year-old wrote this song.
I really like the old-fashioned yet sentimental lyrics.
Did something happen?
You just...
seem a little different today.
Was I too chatty?
Should I go this way or that way?
I feel lost
It's our new target.
Who is this man?
Those who are guided
Have found their paths
(Eunmin Foundation)
You see this, right?
Eunmin Foundation.
It's an educational foundation that manages schools...
from grade schools to universities.
From bribery and employment corruption scandals...
to embezzlement,
we hear about them often enough on the news.
It's an influential yet corrupt organization.
So who's the man?
The man in the video clip...
is the owner of the cloud account.
He's a man named Bang Tae Kyung.
His father is the chairman of Eunmin Foundation.
The woman in the video clip reported Bang Tae Kyung,
and he was taken to court.
But the thing is, he was acquitted...
for lack of evidence.
Rich people certainly get their way with everything.
She can definitely appeal if the ruling...
was not made by the Supreme court.
And he won't be able to get out of it...
if she submits this video as evidence.
It's not as simple as you think.
What do you mean?
Are you going to talk about...
the non bis in idem principle?
No, it's not that.
Bang Tae Kyung has been reported missing.
- He went missing? - Yes.
The missing person report was filed...
three months after the trial,
and he's still nowhere to be found.
Then who's the victim in the video?
Her name is Kim Eun Jin.
(Name: Kim Eun Jin)
But...
according to her file,
she took her own life right after the trial.
Back then,
it was like pure agony.
It's not that different now.
The defendant is found not guilty.
See? I told you.
- Thank you. - You did great.
- Let's grab a bite to eat. - Sure, great work.
I'm sorry to ask you this, but could you take a look at this?
Do you recognize any of these men in this sketch?
Could we wrap up here if you're okay with it?
I have to go somewhere.
Sure.
There are only two things that we've found out so far.
The fact that Bang Tae Kyung is a total scumbag,
and that scumbag went missing four years ago.
We just began, but we've already hit a dead-end.
So far,
the five sketches for each case have always been...
connected in the order they were drawn.
They're road signs that lead us to our final destination.
Hold on a second.
Are you lecturing me about my sketches now?
Anyone would know after working on a few cases.
It's weird that you didn't know until now.
Are you dumb or what?
Did you just call me dumb?
Yes, Lieutenant Oh.
Do you have any good news?
Something new came up,
but I'm not sure if I can say it's good news.
What is it?
It's about the Bang Tae Kyung case.
There's something I didn't catch.
The prosecutor-in-charge...
(Prosecutor Yoo Si Joon)
It was Mr. Yoo Si Joon.
Hey, Prosecutor Yoo. It's been a long time.
You're busy, aren't you? We should have a meal together sometime.
I'm always waiting for your call.
Call me, and I'll be there.
It's been so long since I've seen Si Hyun.
- The three of us should meet up. - Okay, sir.
Hello, sir.
It's so hard to see you around, Deputy Chief Park.
Is there something good going on these days?
Gosh, I've been so busy that I haven't visited you in a while.
I'm sorry, sir.
We work for the government and our citizens,
so it's natural to be busy.
By the way, I read this while I was reading the paper this morning.
It was a proverb about a mantis trying to catch a cicada.
Do you know what that proverb exactly means?
A proverb about a mantis trying to catch a cicada?
Do you mean the one that explains a mantis trying to catch a cicada...
without being aware that there's a sparrow behind it?
I think it means one shouldn't focus too much on what they want...
because that could blind them from seeing...
the future dangers in life.
I see. I think it's a very meaningful proverb.
Don't you agree?
Thank you for letting me start the day with a great saying, sir.
The ambiance doesn't seem so friendly.
The promotion for district attorney is coming up soon.
Everyone's probably lost in their thoughts.
- Sir, I need to take this call. - Okay.
I'll call you soon. Let's drink soju together.
Hello? Hey, Si Hyun. What's up?
Kim Eun Jin's case?
How do you know about that case?
- Hey, Si Joon. - Hey.
You're here.
Si Joon, do you know that man who's trying to kill...
Chief Jang?
No, I've never seen him before.
Can you look closely? It could be highly possible...
that he was involved in Kim Eun Jin's case.
Si Hyun.
I know. You never forget anyone's face.
May I take a look at the other sketches? They might be of help.
Wait.
That scar in that sketch...
It belongs to someone I know.
Who is it?
He's a cop named Baek Woo Jin.
He was in charge of Kim Eun Jin's case.
- Thank you. - You did great.
- Let's grab a bite to eat. - Sure, great work.
- My gosh. - It's over now.
Let's go.
Come on.
Detective Baek was helping Kim Eun Jin with her case.
He's the one who convinced her to go to court when she didn't want to.
But this makes no sense.
Si Hyun's sketches foresee the future.
So it's impossible for Detective Baek...
to have appeared in Si Hyun's sketches.
What do you mean?
Where is he right now?
He...
died four years ago.
Detective Baek?
What are you doing here? It's pouring right now.
Eun Jin died.
Yes, I heard.
I don't know what to say.
She died because of me.
- Detective Baek. - She...
didn't want to take things to court. But I told her...
to trust me.
I promised that I would send that guy to prison.
Rape is not an offense that's subject to complaint.
It would've gone to court whether she wanted that or not.
So it's not your fault.
What are you going to do? You're not just going to end it, are you?
We need to catch him and send him to prison.
We need to make him pay.
There's no more evidence.
Plus, Eun Jin's dead now.
I really don't know.
- I don't know what I should do... - Anything.
Isn't it your job to do whatever it takes?
You're a prosecutor.
So shouldn't you be doing anything you can?
Then what about you? What can you do?
What can you do in this situation?
I'll have to find out.
I'll have to see what I can do.
- Detective Baek. - I'm not going to just end it.
That was the last day I ever saw Detective Baek.
His name's Baek Woo Jin. He was 34-years-old when he died.
His body was totally ruined because his car had caught fire.
They confirmed that it was him by checking his dental records.
The car belonged to Baek Woo Jin himself.
And there was a lot of soju bottles in his car.
His colleagues also testified that he was always drunk...
ever since Bang Tae Kyung got ruled as innocent.
As a result, his death was recorded as a car accident.
But how could Si Hyun draw someone who's already dead?
What do you think of this?
It doesn't need to be complicated. There are two possibilities.
Either the sketch is wrong.
Or...
he's still alive.
I personally think he's still alive.
But is that even possible?
"Once you eliminate the impossible,"
"whatever remains, no matter how improbable,"
"must be the truth."
Sherlock Holmes said that.
If Detective Baek is actually alive,
then whose body was the body that was found at the scene?
There's one more person who suddenly disappeared...
around the time when Detective Baek had gotten into a car accident.
Are you talking about Bang Tae Kyung?
Here are the files regarding Bang Tae Kyung's case.
The record tells us that Detective Baek's car accident...
took place in September 17, 2014.
A report saying Bang Tae Kyung had gone missing...
was made a week later which was on September 24, 2014.
However, his family told the police that they couldn't reach him...
starting from the 16th which was a lot earlier than that.
That's over 20 hours before Detective Baek's car accident.
Are you saying...
Detective Baek killed Bang Tae Kyung...
and used Bang Tae Kyung's corpse to make it seem like his own?
Detective Kang, I think that's a bit too farfetched.
Don't you think so?
There's only one way to check.
They confirmed Detective Baek's corpse through his dental records.
He could've switched his dental records with Bang Tae Kyung's,
but he couldn't have gotten rid of all of Bang Tae Kyung's records.
Let's dig up Detective Baek's grave...
and compare the corpse's teeth with Bang Tae Kyung's dental record.
Yes, okay.
They handed the corpse over to NISI.
Captain Moon's also there, so we'll be able to get quick results.
Even if we confirm that the corpse is...
Bang Tae Kyung, not Baek Woo Jin,
it doesn't solve anything.
Why did Baek Woo Jin fake his death?
How is he connected to the case?
And who's that man in the sketch?
We're not even a step closer to the really important answers.
Yes, Yoo Si Hyun speaking.
Pardon me?
You said there's something you'd like to show us.
It was Eun Jin's favorite necklace.
After what happened to her,
I looked for it, but couldn't find it.
I assumed it was lost, but...
but one day,
I found it in our mailbox.
That must've been after Detective Baek Woo Jin died, right?
You know Detective Baek?
Could we take this necklace and examine it?
Yes, that's why I brought it.
Hold on.
May I see that thing in your purse?
This?
Do you mean this toy?
Where did you get this?
Today is Eun Jin's death anniversary.
I went to see her earlier...
and found it there.
But to tell you the truth,
today wasn't the first time.
After she died...
Right, starting the following year,
someone has been leaving a toy like that at the columbarium...
on her death anniversary every year.
This footage was recorded an hour before Eun Jin's sister arrived.
Unfortunately, that man's face was not captured in any of the cameras.
That man must be Detective Baek Woo Jin.
That doesn't change anything though.
We don't have any concrete proof to go after him.
We're not making any progress.
Detective Kang.
Do you remember what you said to me earlier?
- What? - You said earlier...
that the sketches are like road signs.
You were right.
I'm not following. Do you care to elaborate?
What I'm saying is... If...
What if Detective Baek Woo Jin and that man in the sketch...
are actually the same person?
What are you talking about? They look nothing like each other.
Look at the first sketch.
Do you see the sign for a plastic surgery clinic on the third floor?
Do you think it's a mere coincidence...
that it's shown on the sketch?
So your theory is, Baek Woo Jin got some work done on his face...
and became that man in the last sketch.
And that speculation is based on...
the building with the sign for a plastic surgery clinic.
Lieutenant Oh,
could you zoom in on the man's left hand in the CCTV footage?
Okay.
You see that, right?
See what?
Isn't his watch similar to the one the man in the sketch is wearing?
Don't you think it's worth checking out that clinic?
Yes.
(Joo Min Sang Plastic Surgery Clinic)
It's on the third floor.
- Let's go. - Okay.
- I don't love it. - Why not? It's pretty.
Let me see. Actually, that one is pretty too.
- No. - Don't you like it?
- This one is much prettier. - Gosh, I don't like it.
What's with you today?
- You picked up the ring. - Yes.
How does it look?
D from Dong Soo, and J from Ji Soo.
It's one of a kind.
People think that wolves are lonely animals,
but I heard they actually...
trust and rely on each other a lot more than any other species do.
What?
You know what "howling" is, right?
When one wolf starts wailing, the rest do the same.
It's because they can empathize with each other's pain.
Thanks to his friends who cry for and with him,
the wolf who started the howling can cheer up.
We're a team now, which means you're our friend.
I just wanted you to know that.
Thanks for your concern.
What you just said...
totally moved me and warmed my heart.
I don't say things like this easily, but I really want to say it to you.
Know your place and mind your own business.
You cry your eyes out when no one is around. Don't act all tough.
- What did you just say? - Sorry?
What?
Let's go.
It's over there.
Excuse me.
Is anybody here?
(Joo Min Sang Plastic Surgery Clinic)
Excuse me, are you okay?
Kim Do Jin!
- Are you okay? - Yes, I'm all right.
If you know anything, you should tell us now.
I won't ask twice.
Look at this photo. Do you know this man?
Yes, I do.
So...
are you saying that man in the sketch is Detective Baek Woo Jin?
So...
are you saying Detective Baek is alive?
That plastic surgeon confirmed it for me.
He operated on Detective Baek Woo Jin on October 14.
It was a month after the car accident.
I got a call from Forensics.
As Detective Kang speculated,
the corpse was Bang Tae Kyung.
It was Eun Jin's favorite necklace.
After what happened to her,
I looked for it, but couldn't find it.
I assumed it was lost, but...
but one day, I found it in our mailbox.
Baek Woo Jin. What is his deal?
Why did he do that to fake his own death?
And why is he after Chief Jang Tae Joon?
One more.
Why is Kim Do Jin searching for Baek Woo Jin?
There's no need to make this complicated.
We can answer all of the above...
once we find Baek Woo Jin.
(Adverse reaction to anesthesia. Need additional surgery)
Good work.
Do you have something to say?
You haven't told me who he is,
or why I must kill him.
You told me to have faith.
I believe faith must be given mutually.
Who is this man?
Two years ago,
he tried to kill me right here.
I guess this answer isn't sufficient.
This man is your predecessor.
That's right.
He did your job before you came.
Now, do you understand...
why we must find Baek Woo Jin before the others do?
(Sketch)
After hiding his identity,
Baek Woo Jin punished future criminals.
Just as Kim Do Jin is doing now.
Don't worry. I won't break halfway...
