(All characters, places, organizations, cases,)
(and surroundings in this drama are fictitious.)
A chopped-up body in a suitcase?
And a peppermint candy was found?
A few years ago, someone who had the nation talking...
did the same, right?
- I Su. - Hyun Jae!
Get out of there right now!
I Su!
(Previously)
Is your memory always that amazing...
or do you have a good eye for detail?
I remember everything like a photo was taken.
A photo?
- Is it like picturing? - Yes.
We're meeting someone.
Just tell the person everything you saw.
The Hongwoon incident. Tell me everything you saw there.
Amongst the bystanders...
He was holding something that looked like a leash.
I've never seen him before.
I'm here to confess.
I'm the murderer who killed Go Min Ji.
I'm Peppermint Candy the serial killer.
It got on the weapon recently. Within about 48 hours.
There's a possibility she's alive?
Where is she, you scumbag?
She must be somewhere.
I thought carefully about why you asked to see me.
It's because of The Guy.
You want to know if he's back.
This is for just in case.
Let me join the RIU.
I'll be of some assistance to you.
What about you? Do you have the talent?
Do as you're told from now on.
Is that you, Detective Oh?
Go in the direction without webs.
Follow the ring. It'd be connected to the ground.
Now, find the door.
It's open.
There are too many corpses.
Get out. The space is going to collapse soon.
What if the victim is alive?
- Get out. - What if the victim is alive?
It's fine.
- We're going to make it out alive. - Thank you.
- It's fine. - Why is it...
you want to join the RIU?
I also...
have someone I must catch.
Excuse me. Is The Guy alive?
I'll only tell you the facts.
The Guy officially died from the explosion...
at Junggeon Three-way Intersection.
Is The Guy is alive?
Alive?
Then, he'll show up.
It's up to him.
(Episode 3)
(Evidence: Marks or Traces Left After An Incident)
Who are you?
Save me!
Team Leader Hwang!
This is driving me insane.
How did this happen in our station?
The file.
He took the hard disk.
Get everything from the cameras to the entrance and corridors.
Tae Sung, identify all who entered the station.
- Yes, ma'am. - What were you doing?
I apologize.
I'll call the cyber police and get them on it right away.
Well... Team Leader Hwang.
Could it have been The Guy?
Are you stupid?
- Think about it. There was a candy. - Does that make sense?
How could a dead guy do this?
(Interrogation Room)
What's this?
How did you manage to get a suspect killed in the station?
What'll you do now? What'll you do about this?
- I apologize. - Will an apology cut it?
Who are you?
I'm Officer Cha Su Young from Hongwoon Patrol Division.
Oh, you're...
She identified Kang Seung Hwan's victim.
She was dispatched to our unit.
Good going.
Your juniors are not disciplined. They are a complete mess.
All of you, write up a report.
We'll do so after we solve the case.
What?
Hey, Ha Young.
Yes.
Okay.
Gosh, it hurts. Go easy on me.
Sir, hold on. Wait a second.
(Tell Me What You Saw)
(Mucheon Metropolitan Police)
Yes.
Yes, Commissioner General.
Of course. We'll wrap it up quickly.
Yes.
Do you know who did it?
Not yet.
I think he had inside knowledge.
So are you telling me the culprit is one of us?
We'll know once we investigate.
I heard there was a peppermint candy or something.
Yes.
It's not him, is it?
Do you seriously think so?
The Guy died five years ago.
You saw it yourself too.
What power do I have?
You were the one who checked.
I'm sure it was him.
It's obvious Ha Young will be digging this up.
What should we do?
Should I have sent her somewhere else when I had the chance?
The more dangerous your enemies are, the closer you keep them.
I'll take care of it on my end.
What about the reporters? It will be a huge story.
Well, crises can turn out to be opportunities.
Do you have a plan in mind?
I'll let her have something to chew on, but not the bones.
(National Forensic Service)
Our turn got pushed. I think we have to wait a while.
Ask other teams to wait.
Yes.
Is that so?
Okay.
Make sure you catch the culprit before Ha Young does at all costs.
Yes, sir.
I get that you're in a hurry,
but he just died. How can you ask me to do the autopsy now?
What's the cause of death?
His carotid artery was cut.
It was a clean cut.
A thin and sharp line.
Like a fishing line or piano wire.
It looks like the killer applied force at once.
But this is odd. Here's what's fascinating.
What is it?
There are no marks.
There are no defense marks.
When someone strangles you, you instinctively defend yourself.
There are no traces of that.
He was completely overpowered...
psychologically.
What's the murder weapon?
Something like a fishing line.
He probably wore gloves.
He's not your regular Joe.
It's impossible to put a man...
who weighs 120kg under your control without facing resistance.
Was he in extreme fear?
What about the peppermint candy?
I'll know for sure once I run a thorough analysis on it.
That kind of candy is mass-produced.
The candy is just a message.
And Kang Seung Hwan is the messenger...
for someone.
(Mucheon Metropolitan Police)
What's this about?
No clue. The forensic science team...
came out of the interrogation room earlier.
The forensic science team?
- My gosh. - What's going on?
- He's here. - Hey, he's here.
I appreciate your hard work at such a late hour.
I'll now brief you.
Today, around 2:27pm,
the suspect, Kang Seung Hwan, who was being investigated...
for the serial murders of five victims...
was found dead in the interrogation room.
- What? - He's dead?
- During the investigation? - How?
- Hey, this is a big scoop. - What a story.
Was it a suicide or homicide?
We're still investigating.
Are you sure he wasn't tortured?
We're also considering the possibility as well.
What's the cause of death?
The investigation is still underway, but I can say this with certainty.
We found a piece of peppermint candy in his mouth.
- Peppermint candy? - Is it another copycat crime?
Yes. I'm certain it was done by a copycat.
Is there a possibility The Guy is alive?
No.
To stop the spread of unnecessary doubts and strange rumors,
we are announcing our findings.
We, the police,
will apprehend the culprit as soon as possible...
and do our best to earn...
your trust.
- We have more questions! - Could you elaborate?
- One more question! - Sir!
- I have one more question! - Are you sure it's not him?
- Can you explain that in detail? - Wait!
- Is that it for questions? - Did you find any other evidence?
- Was the suspect coerced? - Please answer one more question.
This afternoon, around 2:27pm,
a serial killer, Kang Seung Hwan, was murdered...
inside the police station. This incident shocked the public.
A peppermint candy was found in his body.
It intensified people's curiosity about the incident.
It is Team Leader Hwang Ha Young.
Speak.
What do you think?
I'm not sure.
Could it really be him?
It's not his style to be indiscreet.
When serial killers undergo cooling-off periods,
their MOs change.
We'll know for sure once we catch Kang Seung Hwan's killer.
We must catch him before Chief Choi does.
I need to take another look...
at Kang Seung Hwan's case.
I stocked up your fridge. Don't skip meals.
And take this 30 minutes after your meals. After, not before.
(Diazepam)
If you're tired, take a break.
No. I'm fine.
Thanks.
What is it? Did you find something?
No.
Let's call it a day today.
Okay.
(Mucheon Metropolitan Police)
It's been a while, Lieutenant Hwang.
Come on. Don't be a stranger.
We used to work on the same team.
That doesn't mean you were close with everyone on the team.
I thought we were close. Was I wrong?
Bye.
Any news about Detective Oh Hyun Jae?
You know, I was just looking out for my colleague.
Tell him to call me if things are tough.
I'll look for a spot on a TV show.
I'm sure he can still talk, can't he?
Why do you keep thinking about him?
I guess you were very fond of him.
You treat him as if he's your rival when he's not.
And you make it sound like you're sorry.
It seems you're obsessed with him.
See you around. I get the feeling we'll cross paths more often now.
Man Su.
Isn't that Na Jun Seok the profiler?
They were on the same team. Are they not friendly?
When he was at the RIU,
Oh Hyun Jae made him look bad once.
He said an innocent guy was a suspect...
and made him take his life.
Did he hear me?
Dad. What is it?
(I haven't heard from you at all.)
Sorry, Dad. I'm at work right now.
Hey.
However busy you are, call your dad sometimes.
The whole neighborhood's worried about him.
You look after him yourself.
Gosh, you're shameless, aren't you?
Why do you think I'm here right now?
(You're busy. Hang up. Get back to work.)
Okay. Bye.
Hey.
Gosh. The brat's pretending to be busy.
Mung Chi, come here.
Mung Chi.
- Mung Chi, come here. - You're cute.
Mung Chi.
Mung Chi's quite friendly.
Yes. Mung Chi, let's go.
It's okay.
Mung Chi looks a bit sick.
He was fine a while ago. What's wrong?
Mung Chi, are you okay?
Can I have a look?
I'm a veterinarian.
Okay.
- Mung Chi. - Oh, dear, Mung Chi.
Listen up.
Let's begin the RIU meeting.
- Begin. - Okay.
We focused on...
people Kang Seung Hwan knew or those who'd have a grudge,
and checked if any...
had committed crimes using fishing equipment.
We identified seven people.
One of them is definitely the killer.
What we must remember is that there's no perfect crime.
There are only imperfect investigations.
The result of that...
- causes more... - Kang Seung Hwan...
is delusional and antisocial.
He's impulsive and unpredictable.
That makes him hard to control.
And...
he planned a crime on his own?
Track where the suspects went,
and tell me if you find anything suspicious.
Come to my hideout. There's something I want to hear.
Okay. You heard him. RIU Team Two,
question all the suspects.
Team One remains here to back them up. That's all.
Chief Choi. You can't do that.
This is our case.
The suspect died under your supervision.
- You're suspects too. - We're suspects?
How can you do this to your own people?
It ended at this because you're my people.
Be glad you weren't suspended.
No one calls dibs on cases.
Everything's shared.
You should've watched the suspect closer then.
How dare you?
Team Leader Hwang.
Will you just let them mock us like that?
Enough. That's rich coming from you.
My pride is what keeps me going, and this is just too much!
You don't investigate with your pride.
Let's catch him first.
Good boy. You did very well.
Rub the injection site a bit more.
- You were worried, weren't you? - Yes.
Have him admitted today and...
visit him again later.
Thank you. I was lucky to meet you.
Mung Chi must be like you. He's very calm.
You don't have to pay for today's treatment.
- Thanks so much. - Sure.
Do you take photos as well?
It's just a hobby. When you come back later,
I'll take one to celebrate Mung Chi's discharge.
- Will you really? - Yes.
Thank you.
Mung Chi, I'll come back later.
- Bye. - Take care.
See you later.
I'll finish up. You can go home.
- Okay then. - Go.
You did well today.
Come along.
(Animal Hospital)
Is anyone in?
Doctor, I'm here for Mung Chi.
Doctor?
You're early.
Doctor. Where's Mung Chi?
His condition suddenly worsened. He's in the treatment room.
Is he very sick?
I thought he'd recover, but it doesn't look good.
I think...
I should explain the situation inside.
- Okay. - Follow me.
Okay.
- What is it? - What?
What's wrong?
Well...
Oh, this?
No, well...
- The thing is... - What?
Save me. Save me!
(Animal Hospital)
(Call history)
Hey. Are you still going through the call history?
Yes. It's a long list.
- Your towel. - What?
- Do you have something? - Not yet.
Darn it.
Is anyone here?
Help me.
"Help me."
(Restricted Entry)
Darn it. I might get found out.
No...
It's not fun anymore.
Shoot.
Darn it. Blood.
Darn you. I'm sick of this.
How far are you going to run?
My gosh.
Hey.
Are you dead?
That's just boring now.
It's Cha Su Young.
Are you in?
When we're done with 1500-1, 6B1 will take it.
6B1 will take it.
Acknowledged. Over.
Headquarters?
This is 6B1. 6B1 will take it.
When we're done with 1500-1...
(Kang Seung Hwan Investigation Report)
(Personnel Card)
(NFS Report)
You got here earlier than expected.
Consider it a weirdo's weird hobby.
You were waiting for The Guy to reappear.
I thought about it,
and I think Kang Seung Hwan has an accomplice.
An accomplice?
Then was Kang Seung Hwan killed by that accomplice?
If the accomplice was at the station that day,
it would be to find out how the case was progressing.
Do you remember anything?
Or the people you passed by?
I can't picture everything I see.
Before,
you said if you're very nervous...
or in an unfamiliar setting, you end up...
remembering everything you see.
Yes.
What if...
Could it be that...
your mind stored the images somewhere,
and you just aren't aware of it?
To tell you the truth,
I never thought of that.
How about it?
Shall we see?
Now?
- Yes. - Here?
Yes.
Okay, then. Close your eyes.
Go on.
Let's suppose you're at the police station.
Bring up all the images...
you saw that day 1 by 1.
There's nothing special. Just...
police officers, civil petitioners, staff.
Keep going.
How about a plate of yellowtail amberjack? They are in season.
Don't you know that I can't eat sashimi? Will Ji Min be late?
No, he'll join us soon.
Wait. There's this guy.
He looks like he's in his early 40s.
His back is slightly bent,
but he seems to be well-built.
He has a habit of cracking his neck.
It'll be an unusual thing he does when he's excited or nervous.
Anything else?
I'm not really sure.
Focus a bit more on what you see.
Do you think you're missing anything?
On the back of his hand... There's a black smudge.
But I don't know what it is.
It'll be a mole or a tattoo.
Wait. He has a black umbrella.
It's the umbrella I saw at the Go Min Ji crime scene.
It looks like the same guy.
What's his connection with Kang Seung Hwan?
The leash that Kang Seung Hwan had,
and the collar on the dog the man had in his arms.
It looks like a set.
Good.
Now open your eyes.
There's a clue we're missing.
Go to Kang Seung Hwan's home now.
I'm in.
Now. What is it that...
we missed?
They already took everything related to the case.
Kang Seung Hwan liked to show off...
and was full of himself.
He will have left a trace.
There are a few photos.
They're mostly selfies.
A lot of them are with his dog.
Cha Su Young. Keep quiet and still.
What?
There's someone else.
Get out of there.
Cha Su Young. Cha Su Young.
This is RIU Team Two.
We're heading to Kang Seung Hwan's home.
We're here. We'll bring the rest of the evidence.
Cha Su Young. Do you hear me?
Cha Su Young?
Yes.
Cha Su Young. Are you hurt?
No. I'm okay.
I'll go after him.
There's no need to.
He'll have come to destroy evidence.
Find out what he took.
I don't know.
Nothing has changed.
Something definitely has or he wouldn't have gone there.
RIU Team Two will be there soon.
Can you find it before they do?
Yes, I'll give it a go.
Focus a bit more.
Focus.
A photo's gone.
One that was taken with a dog.
There were many photos with a dog...
and he took just that one?
The background is different...
and I see a man taking photos in the side-view mirror.
He's an accomplice.
Get out now.
(DO NOT ENTER, Under Investigations)
Go in and take everything!
Yes, sir.
What relationship did the two have?
Seung Hwan...
went back to find the dog,
because the dog was like family to him.
The accomplice...
probably used the dog to get close to Seung Hwan.
He probably works closely with animals.
Su Young...
saved the day once again.
She's a funny girl.
She doesn't know how capable she is.
She'll learn.
She works hard but is clumsy.
She's scared,
but also courageous.
What's important...
is that we need her.
(Mucheon Metropolitan Police)
Look through the surveillance camera from the police parking lot...
and find footage from the day Seung Hwan died.
Track the car with the plate number 67, H6677.
Let's see.
The car owner's name is Jung Chan Ku.
There's nothing else peculiar.
Did you just say Jung Chan Ku?
Why?
He called Seung Hwan five months ago.
- Just once. - What?
- Yes? - Check if any cars that day...
were owned by a vet or a pet-related organization.
Will do.
- What did she say? - Check if cars that day...
were owned by a vet or a pet-related organization.
(Personal Profile)
(Veterinarian)
Chan Ku is a vet.
Bingo. Let's go get him.
Give us his address...
- and keep looking into him. - Will do.
Su Young, come with me.
Yes, sir.
We're on our way!
Yes.
(Animal Hospital)
Team Leader Hwang, we have a suspect.
His name is Jung Chan Ku, 43 years old.
He's a vet as you've mentioned.
I'll send you his address.
- Send it to her. - Okay.
Team Leader Hwang is amazing. How did she know?
He got married seven years ago, but he's single now.
His wife is missing.
He has no criminal history.
I've looked into him...
and he treats abandoned dogs and volunteers a lot,
so people around him have good opinions of him.
But he had an issue with his neighbors...
because of foul odor and loud sounds coming from his place.
- What foul odor? - The smell of things burning.
Please let me live.
Keep looking into him and keep me updated.
And send a photo of Chan Ku to Tae Sung.
I got it.
It's this guy.
He looks so normal.
Please let me live.
People like you are less worthy of being than dogs.
Bark if you want to live.
Please.
Bark.
Why are you doing this to me?
I'm...
not feeling too happy today because of psychos like you.
But seeing blood makes me feel better.
(Animal Hospital)
Please let me live.
Please.
Please!
Stay still.
What?
- Darn it. - Darn it.
The animal hospital here is closed.
I've called the Veterinarian Association...
and Chan Ku's vet license is suspended.
His hospital is closed permanently.
But what's weird is that his credit card history suggests...
that he bought medicine for animals until very recently.
The receiving address isn't far from where you are.
Have a nice day.
She says she doesn't know.
Someone else picked up the parcels.
Look into every animal hospital in this area.
I think he still may be practicing as a vet nearby.
It must be near here. This is driving me crazy.
Detective Oh, I'm Su Young.
Do you hear me?
Try to think of the photo he took.
What?
The missing photo.
Yes, sir.
There's...
a painting at the back.
Find it.
Please let me live, please!
(Mimeum Real Estate)
Please let me live, please!
(Animal Hospital)
Team Leader Hwang, I found the animal hospital.
Hello.
(Animal Hospital)
I'm the police.
What brings you here?
(Run, if you don't want to get caught.)
What?
We're just going to investigate the site.
So this is why he didn't get caught.
(Kim Jin Heon)
There's nothing much here.
Neighbors said that they smelled something burning.
There must be a furnace somewhere.
There's a gap between the closet and the wall...
in the photo.
Team Leader Hwang,
this closet seems off.
(Animal Hospital)
It smells like blood in here.
(Identification Card)
Team Leader Hwang.
These must be the victims' things that Seung Hwan killed.
This guy is insane.
(Identification Card)
Be quiet.
Hold on.
Team Leader Hwang!
She's alive.
Ji Min, call the ambulance!
Calm down, it's the police.
Team Leader Hwang, here!
Ji Min, contact the Public Security Department...
and have them check the cameras on the streets.
Chan Ku's car, 67, H6677...
is heading to Highway Seven.
You head to Highway Seven.
Text me when you find him.
Chan Ku's car is heading towards Gugu-dong.
You'll run into him at Namu Intersection.
Detective Yang, there!
Right there, he changed his lane.
Stop the car, Chan Ku!
Stop the car, I said!
Stop it!
Get out of the way!
Darn!
This is so frustrating.
Working hard, I see.
I came because I didn't get a reply.
Is our deal still on?
Seung Hwan and Chan Ku...
were doing criminal activities on their own,
then they began to work together.
Chan Ku would attract the victim's attention with the dog,
then the two kidnapped the victim together.
What Seung Hwan wanted was photos...
and what Chan Ku wanted was to murder.
But one day,
someone set Seung Hwan off.
He started going crazy because he wanted to get famous.
Then eventually, he brought himself to the police.
Chan Ku, being an accomplice, was scared that he'd be caught,
so he came to the police station...
to check on how the investigation was going.
And then...
Seung Hwan died.
Team Leader Hwang, we found Chan Ku's car.
He's heading towards a port.
There's a possibility of him getting on a cargo boat.
And...
Team Two is following.
Alcohol inspections.
Attention patrols.
If you see...
a white car with plate number 67, H6677, arrest immediately.
It's this car! Get him!
- Get him! - Quick!
We have to get that car!
Just a few days ago,
- Seung Hwan the serial killer, - 67, H6677 is fleeing the site.
- has been murdered. - 67, H6677...
- was stopped at the intersection, - Who killed him?
- but fled from the police. - Is it really...
that Peppermint Candy came back alive and killed him?
As you all know,
peppermint candy is The Guy's symbol.
Why did Seung Hwan's murderer...
put a peppermint candy inside Seung Hwan's mouth?
Here's an interesting question...
from username Peppermint Candy.
"What are we going to do..."
"if The Guy is still alive?"
Do you think that's possible?
I'd bet my life if I could.
It's time already.
Why is he not here? He took my money.
(Restricted for the public at night)
It's so cold.
Kitty?
Where did it go?
My goodness!
You can't be here.
I lost my phone.
May I borrow your phone?
- Where are you? - I'm on my way. I'll be there soon.
Hurry. You must catch him first.
Team Leader Hwang!
He's dead.
He's probably around here. Look for him again.
What? Gosh.
Darn it. Call an ambulance right now.
That way.
Over there.
Su Young, you go with Tae Sung.
- Yes, sir. - He still might be at the scene.
Be careful.
- Radio us once you found him. - Yes, sir.
Come with me.
Darn it.
Hey, go that way. I'll go this way.
- Okay. - Okay?
(Cold Storage)
Detective Jang.
I found bloodstains on the handle of cold storage number three.
Where are you, Su Young?
Hey, I can't hear you at all. Can you hear me?
Su Young.
- Detective Jang, I'll go in first. - Come over here. Okay?
Hey, Su Young. You can hear me, right? Come over here.
Su Young. Hey.
It's me.
There's a frequency jammer.
You can't communicate through radio.
- Okay. I got it. - Be careful.
You don't know what he'll do.
Okay.
Hey.
Su Young. Hey. Where on earth are you?
It's storage number three.
She's in danger.
- That way. - Okay. Who was that on the phone?
(The scenes with the animal was staged.)
(It was filmed safely under the supervision of an expert.)
(Tell Me What You Saw)
We didn't find peppermint candy this time.
I thought about what we might have missed.
I am sure the same guy committed these murders.
Who is his next target?
Will you keep your promise that you'll bet your life...
if The Guy is alive?
If he's the real culprit,
who was it meant for?
How could he...
manage to kill in front of people...
without revealing himself to us?
The Guy finally resurfaced.
