Previously on Return.
I think we've done too many bad things. Let's turn ourselves in.
Dal Rae!
- I don't believe you anymore. - Min Young.
I'm going to do it my way now.
You jerk.
Are you the one who stabbed Dong Bae?
Choi Ja Hye, you are under arrest for the murder of Yum Mi Jung,
Ahn Hak Soo, and Ko Suk Soon.
Thanks to you, I get to talk to my friends in private.
Thank you.
Please don't mind me here, and have your conversation.
Could you leave this room for us to talk freely then?
Sure.
Suit yourself.
I brought you here so that you can relax for a bit.
Why were you so careless?
You should've hidden the knife too.
You told me not to throw out the knife.
Who would have known this would happen?
You got arrested again.
I can't believe you.
Our table could turn, you know.
Who do you think caused all this mess to begin with?
Are you saying that I caused it?
- You guys... - Have you forgotten?
You were the one who drove the car.
You told us to throw the girl into the water.
You're not remembering it correctly.
Remember who burned down Choi Ja Hye's house?
It was your father, Mr. Oh, who ordered...
Mr. Yum to set her house on fire.
Is that what Mi Jung told you?
Your family opened a wine bar for her...
and paid that expensive rent every month for her. Isn't that...
Be quiet.
Do you think Choi Ja Hye is livid with us only because of...
what we did to her daughter?
- She even murdered Mi Jung. - Drop it.
I pulled some strings for you because we are friends, you know.
See you around.
You don't look so good by the way.
What's going on?
I'm sorry.
I... I should have done more.
I'm really sorry, Na Ra.
Didn't he already hit rock bottom?
I thought the last incident was was his worst, but it wasn't.
I think he couldn't possible stoop lower, but he managed that.
How should I explain this...
to my daughter, Dal Rae and my baby?
What should I say?
South Korea and North Korea have decided...
to enter separately for Pyeongchang Paralympics Opening Ceremony.
- Dal Rae. - Yes?
- Let's go take a shower. - Okay.
Choi Ja Hye, the host of a TV show, Return and a celebrity lawyer,
- was arrested as a prime suspect... - That's the lawyer lady.
- What? - for serial murders that...
took place from December, 2017 to February, 2018
The police had difficulties...
in pinpointing a suspect as the three murders...
occurred in three different places and turned the case over...
- Dal Rae. - to the RIU.
Go brush your teeth first.
- The regional investigation unit... - Okay.
concluded Choi Ja Hye as the prime suspect for these murders...
and apprehended her.
The police plan to investigate...
in relation to Choi Ja Hye's involvement in these murders.
Yes, this is Violent Crimes Unit One.
What a surprise. Why is the regional investigation unit calling us?
Why do you want Lieutenant Dokgo?
What is it?
You want us to put him on the Roman Numeral Serial Murders?
My gosh.
Dong Bae, how are you holding up today?
Hey, punk. I brought you something delicious today.
Ta-da.
I bet you are craving this.
All right then.
A glass for you.
And a glass for me.
Cheers.
If you won't drink yours, I'll drink yours too.
Don't you want to drink this?
Then wake up now. Wake up, and let's drink.
Another glass...
Hey, isn't this noisy?
If it is, why don't you wake up...
and say something?
Fight back.
Dong Bae.
Wake up and fight back.
You're the only one who fights back at me.
Please.
Dong Bae.
I'm sorry.
You can get in trouble,
fight back and yell at me.
Just wake up.
Please.
Hi, Won.
The regional investigation unit called.
They said you can join the Yum Mi Jung case.
That's right. This is how it should be.
They're the ones who snatched the case away.
They want to do it right now, is that it?
Okay. I'm here.
Why me?
You said enemies often turn into friends.
You removed all hatred in your tone, and are even joking.
But...
am I included in your plan?
Because I once got off for being a minor?
You know that although I have a past,
I can't accept what you did.
I don't know what you mean.
Fine. Given what it is,
let us begin.
Let's start with your relationships.
Kim Jung Soo, Tae Min Young, Kim Dong Bae.
Do you know them?
We're with the police.
(National Police Agency Gyeonggi Province)
Why are you refusing visitation?
Because I don't need a lawyer.
I want to ask you something.
About my husband's case.
I looked into it,
and he thought I was at your mother's house,
and went to your apartment to look for me.
But...
he said a detective was there when he got there.
I don't know either,
why a detective was in my apartment at that time.
My door lock was busted too.
Do you want me to help you with this case?
It's okay. I'll take care of it.
You can't handle this.
You don't trust me.
It's not that I don't trust you.
I just don't want to burden you,
especially while you're pregnant.
May I ask what happened?
How could you be a suspected serial killer? That's absurd.
It's nice to know...
someone trusts me.
This isn't about trusting and not trusting.
Tell me what happened.
Only my attorney...
will know the truth.
If you don't mind,
may I take on your case?
I guess not, right?
Do you really...
want to be my lawyer?
No matter what truths...
you come face-to-face with?
If I can...
start something over again by my own volition other than marriage,
I'd like...
this case to be the starting point.
It's so annoying.
Tae Suk, that jerk,
still thinks I'm a fool.
In Ho killed a detective in Choi Ja Hye's place?
What's that about?
When you kill someone,
how can you disguise the murder?
Accidental death...
or...
something like a mugging like in that movie.
Bum.
Take care of Joon Hee.
That's what that was!
That punk Tae Suk thought really hard about this.
So, he left Joon Hee to me,
and had Mr. Kim tie In Ho to...
That punk.
What's this?
That means I'm next.
Not a chance.
I can get rid of Tae Suk...
first.
(Soy sauce)
Why does a famous TV celebrity...
live like this?
Why is there a bathtub in the middle of the room?
Thanks.
Please enjoy. I'll let you talk.
See you.
Hey.
I felt this way with Mi Jung's case...
and again now.
Doesn't this feel sort of like a Hollywood movie?
I mean, look at us.
Two lead guys meeting in a police station.
Hey. Drink.
It isn't easy to have a visit...
in the police chief's office.
I've already talked to Tae Suk in here.
Tae Suk came to see you?
Yes. He came two days ago.
What did he say?
It's none of your business. Say what you came to say.
Hey.
Are you still mad about your wife?
You jerk.
Just say what you came to say.
Why did you...
go to see Choi Ja Hye?
I don't feel like telling you.
Tell me.
Something irks me, that's why.
Tell me.
How did you find her place and end up there?
I was on the phone with Dal Rae.
I heard that Na Ra and Dal Rae were at Choi Ja Hye's house.
That's why I got her home address and went to that apartment.
But then...
why did you stab the detective with the knife?
I already told my attorney.
I didn't stab him on purpose.
- What then? - It was an accident.
- "An accident"? - Yes.
Someone wrecked the door lock.
Na Ra and Dal Rae could have been in there,
so I got scared.
That's why I hurried inside.
I heard a man's voice behind the wall.
Where are you?
Why did she hide a secret room here?
Behind the bookshelf, there was a room.
"A room"?
Yes, a room.
The bookshelf was pushed to the side.
That detective with the knife emerged behind that bookshelf.
That's when we started to get into a fight.
Both of us lost balance.
When we fell, the detective got stabbed.
I got scared, so I ran out of that place.
I did some digging.
The knife you stabbed that detective with was found in your house.
That's the weird part.
I left the knife behind.
but Tae Suk had that knife.
- Tae Suk had it? - Yes.
After I got the knife from Tae Suk, I hid it in my garage...
just like he told me to.
I did that because...
the police released photos of a suspect on TV.
Hey, Young. Look at you. You look beat.
Did you find anything?
They will have to release Choi Ja Hye soon, right?
Yes, probably.
If the evidence isn't enough to convict her,
presenting the evidence might backfire.
During the estimated time of Yum Mi Jung's death,
Choi Ja Hye had a seminar with other attorneys.
It's in her record that she stayed in Japan for a week.
Say that Kim Jung Soo killed Yum Mi Jung.
Ahn Hak Soo was murdered in the afternoon on February 11.
Kim Jung Soo was in the detention cell that afternoon.
Choi Ja Hye was at the cinerarium.
This concludes that either Tae Min Young...
or Kim Dong Bae murdered Ahn Hak Soo.
- Won. - Yes?
Where was Dong Bae from 1pm to 3pm...
on February 11?
I don't remember.
It was my birthday,
so Dong Bae bought me lunch.
- Are you sure? - Yes, I'm sure.
My goodness.
We made a fuss of arresting her for nothing.
- Exactly. Darn it. - My gosh.
Nice.
Why did you ask me to come over?
You came.
Hey, look at this.
Hey, don't you think I can hit pretty far with this?
What are you doing?
I don't know.
What do you think I was doing,
my friend?
Why are you getting on my nerve too?
I can't reach Mr. Kim.
I told you that I sent him abroad!
That's why I looked into that.
There's no record that he left the country.
What happened? What is this?
I clearly instructed him to go to China.
Seriously?
There shouldn't have been a mistaken then.
You are smart too.
Why did you mess up like this?
You're stupid.
What's your plan?
I see.
You did those things...
because I'm stupid.
You were going to frame...
Mr. Kim after killing Choi Ja Hye.
That's not it. Were you going to frame In Ho for it?
And you ordered me to kill Joon Hee.
You, jerk. You are...
a piece of trash.
It disgusts me that I'm hearing...
such harsh words from you,
out of all people.
Tae Suk.
Don't betray me.
I don't know about other people,
but you cannot betray me. Don't you agree?
Don't worry. It won't affect you.
A while ago,
a body of an unidentified man was found in Lake Shiwha.
There's a gunshot wound on his head.
- Is that Kim Byung Gi? - I wouldn't know.
If he's reported missing,
it wouldn't take long to find that out.
Tae Suk.
You said it won't affect me.
I will trust you on that. I will.
We should...
try to be more trusting of each other, okay?
Oh, right. You jerk.
If you keep toying around with the gun, you'll be in trouble.
Got it?
Shot.
Hey.
Jin Joo is nice and innocent.
Take good care of her.
Doesn't Tae Suk have a private safe?
Why do you ask?
Do you need money, Bum?
That's not it.
I just want to pull a prank on him.
What kind of prank?
Well...
My gosh.
Jin Joo.
Can't you tell me where it is? Please?
I should know what the prank is for me to tell you.
Hold on. Wait a second.
- You scared me. - Why would you be scared?
You're a delicate woman.
You better not climb up the stairs.
- Is that so? - Yes.
But where is it?
- Come here. - Where?
It's right here.
Hak Bum.
My good boy, Bum.
(Choi Ja Hye's burner phone conversations)
(I told you they wouldn't change.)
Even in Tae Min Young's email,
the same word was misspelled.
That means this...
came from Tae Min Young.
Looking at the spaces between words,
they were sent by different people.
That means at least three people used this phone.
(Demeter Law Firm)
You must've brought an arrest warrant this time.
This is your office. Let's just go.
So, we meet like this again.
I guess you found evidence proving I'm the killer.
The hardest puzzle to solve in this case...
was your alibi.
However, Kim Jung Soo, Kim Dong Bae, Tae Min Young, and you...
Once I figured out your relationships...
with proof, not just speculation,
it was very easy to solve.
You're not surprised.
I guess you hid this in the doll on purpose.
You left the window open on purpose so that I'd find your secret room.
Is that right?
Kim Jung Soo did the same.
He gave me information about himself little by little.
As if he was telling me to find out what's at the end of the tunnel.
He left a trace of a book on his desk for me to see.
He left a notebook in the drawer that matched that shape.
Then, he left a hint inside that notebook.
I decided...
to pretend to be fooled.
"There must be something there."
"Sure, he must have a reason."
But you were at the end of the tunnel.
Why am I suddenly afraid?
Just like Kim Jung Soo turning himself in,
if you are sitting here across from me...
was part of your plan,
what is at the end of that tunnel?
Just do...
what you've been doing...
all this time.
Make me stand trial.
Don't get tired.
Please.
