[ominous music] [Billy] They must have the coke on board.

[Hannah] Billy, come on.

Sit tight till they row the boat.

We want to catch them in the act.

My source is Christian.

Christian is my source.

Where did you get this?

-Davor's laptop.

-Shit!

Christian, who is he?

A friend.

What does he mean, you're his source?

He was a police officer.

Was?

They killed him.

And this proves it.

If they've known all along, why have they left you alone?

Where's Davor's laptop?

In his study.

Christian, look-- [Davor] Bianca!

Where have you been hiding?

Mom sent me to find a cardigan.

I just remembered her favorite one's at the laundry room, so I was just going to... [festive sounds downstairs] Have you seen Christian?

He's in the spare room.

You spoke to him?

Briefly.

He's, um, not feeling well.

What the hell is this?

Where did you get this?

Has Christian seen it?

What have you done?

[sighs] [knocks on table] [intro music] [suspenseful music] There's something wrong here.

Why the fuck is it empty?

[phone vibrates] Mom, it's a trap.

Sean talked, they have it on video.

They've known about it the whole time.

Billy!

Billy, get out!

Get out of there!

[explosion] Mom?

Christian?

Hannah, are you okay?

All call signs, this is Magpie.

I have a code zero.

I repeat, code zero.

I'm at Porlock Cove.

Officers down.

Urgent assistance.

Urgent!

[gunshot] [gunshot] I'm coming back.

Armed police!

Drop your weapon!

On the ground!

You fucker.

On your knees!

Hands behind your back.

-[gunshot] -Oh!

Davor said you might need backup.

[Zvonomir] Fuck knows where she came from.

You think they're all dead?

[Zvonomir] The ones I could find.

Should we check?

[police radio] Message received.

Backup's on the way.

[Zvonomir] We should head out of here.

[suspenseful music] Damn it!

Back, back, back!

Let's finish this.

[Davor] This is a token of my appreciation.

He's moving fast.

Too fast.

He's on that bus.

Overtake it!

Overtake the bus!

Pull in at the next stop.

[breathes heavily] [Officer] She called it in, so she has to be here somewhere.

[Officer] Two confirmed dead.

DCI Carter?

Who's the other one?

Unknown male.

They haven't been able to identify him yet.

The others?

[sighs] Billy Murdock is in a bad way.

Hannah is just about conscious.

Did she say anything?

About what they were doing here?

She's in shock.

Any word from Fran?

Not since she called it in.

A fucking shit show.

[retches] Officer?

In the trees.

She's back there.

Oh, Jesus.

They found her.

[soft tones] [voice message] This is Christian.

Say something.

[On TV] By the huge explosion with reports that the resulting fireball was visible more than 20 miles away.

-[Dubravka] Davor!

-[sighs] Oh, I've been so worried.

[On TV] Police are refusing to confirm whether they're treating the incident as terror-related.

Two officers were airlifted from the scene to the Bristol City Hospital.

One of them remains in a critical condition.

[Davor] You left two of them alive.

[Zvonomir] It didn't go to plan.

It was the one thing we talked about!

[sighs] Christian ran.

[Davor] He got away.

[sighs] But I got the laptop back.

And the consignment was safely delivered, so.

I want you to go to this accountancy office.

[Davor] And we open the restaurant as usual.

Just like any other day.

Where's Bianca?

I'll go get her.

[Davor] I don't believe you.

I told you.

I've no idea where he is.

I don't understand why you are protecting him.

[Dubravka] Is there something going on between you?

[Dubravka] So, you'd put your feelings for some man you hardly know ahead of your duty to us?

And what duty is that?

We are your family.

You're butchers.

[Dubravka] How can you say that?

After what happened to our family?

You killed that police officer.

And you killed Stefan.

Bianca.

You lied to me.

[Davor] Christian shot Stefan.

He may have pulled the trigger, but it was you who killed him.

He was becoming a liability, Bianca.

[Davor] You've spoken to her.

Did you give her a copy of the video?

-Did you?

-No.

I told her about it but I never showed her.

I wish I had now.

-If you turn against us... -[Bianca] What?

You'll kill me, too?

We'll do everything necessary to protect the family.

Davor, you need to come down now.

Everything okay?

Come with me.

What the fuck are you doing?

What the fuck are you doing?

We agreed no meetings without my say so!

We agreed no more fucking killing!

That's two more of my colleagues you've murdered!

[Officer] I didn't sign up to this.

You are jeopardizing everything!

Oh, that's rich coming from you.

This whole fucking place is under surveillance.

No, it's not.

I'd know about it!

You don't know everything.

Who, then?

Those colleagues of yours.

The ones you thought might have been reassigned.

Billy Murdock?

Hannah?

Her son's been working here.

Undercover.

Fuck.

We've known about it.

Since when?

Oh, since the beginning.

The dead cop planted him.

And you've just let him carry on?

[sighs] We fed him false information.

About a decoy operation.

Last night.

-Does he know about me?

-[scoffs] Come on.

If he did, would you be here?

And you're taking care of it?

Yes, we are in the process of it.

150 kilos?

That's the only bit that I'm sure of.

Davor can't have known that his meeting with the Calabrians was bugged.

But that submarine was a decoy.

If it was even used.

Or maybe it was docked elsewhere while we were sent on a wild goose chase.

Either way, they smuggled a shitload of coke into the country.

-That's what you're telling me?

-[Hannah] Mm-hm.

And you're absolutely sure about this?

Why go to all that trouble otherwise?

What a fuck up!

Why didn't DCI Carter tell me about this?

Why didn't any of you?

We... We felt that it was too risky.

I'm in charge of the department!

We think that someone in the team is on the Mimicas' payroll.

You have proof?

It's the only logical explanation.

We thought that it was the best chance of nailing Sean's killers whilst also trying to protect Billy's contact.

Ah, yeah.

This confidential contact you fed cock and bull story.

They were deceived.

We all were.

Maybe they were in on it.

And you won't tell me who they are.

Billy wouldn't divulge.

He said it was safer.

Will they testify?

I don't even know if they're still alive.

All right.

[sighs] Do we have any evidence of any of it?

Uhm, I've got Billy's files.

I've got a few photographs, and a recording of the meeting.

Which may be inadmissible if we can't say who BIlly's contact is.

We really need to find that footage of Sean being tortured.

If it even exists.

[suspenseful music] Billy.

Billy, can you hear me?

Billy, please.

If you can hear me, then...

Please, this way.

Sorry.

-Hi.

-Hey.

Could I just go to the toilet quickly?

Hurry up.

Don't follow me.

[Hannah] I didn't know if I'd find you.

Have you heard from Christian?

[Hannah] I was going to ask you that.

Not since he ran.

So, he's alive.

I think so.

They're still looking for him.

Did you know he was working with the police?

I'm a police officer.

[Hannah] So, you haven't heard from him?

No.

Why would I?

It's just that I thought that there was something between the two of you.

Did he say that?

Not in so many words.

[Pavle] Bianca!

Just a minute!

Shit.

-Give me your number.

-Yeah.

If you hear from him, will you tell me?

-Yes.

-Can I trust you?

Ask your colleague.

Fran Keely.

No, wait.

[flushes toilet] Hi.

Sorry.

[phone vibrates] [Kane] Another associate of yours, I believe.

My sister's fiancé.

Stefan Vargic.

Why didn't you come forward with any information about his killing?

I thought he was in Croatia.

You don't seem surprised he's dead.

Or very upset.

Well, Stefan mixed with some bad people.

Like you.

Hey, you can check his record.

This weapon was used to kill Sean Hardacre.

A serving police officer who was shot dead in the line of duty.

Uh-huh.

Yeah.

I heard about that.

My commiserations.

The ammunition that was used in Sean's killing was identical to the bullets we pulled out of Stefan Vargic's body.

[Davor] Mm-hm.

Don't you have a suspect in custody for that murder?

Andri Kabashi.

Perhaps you could ask him about Stefan Vargic.

Andri Kabashi is dead.

We have absolutely nothing that ties Davor Mimica or any of his family to either murder.

-We searched the restaurant.

-And the house.

-There were no weapons.

-No drugs of any kind.

And definitely no footage of Sean Hardacre being tortured.

In fact, we found nothing at all to support your account of your investigation.

[Officer] But we had a confession from Andri Kabashi.

And what about the explosion?

How do you account for that?

I followed Zvonomir to the scene.

Come on, Hannah, you have to admit you can't be sure it was him.

You didn't get a close enough look to identify him.

Give us the room, please.

[Kane] The only thing we found in the safe house was this.

Oh, come on.

You surely don't believe that Billy and I-- [Kane] I don't know what to believe anymore, Hannah.

You're suspended.

Effective immediately.

[doorbell] [Davor] Oh, that's brave of you, coming here.

Well, my colleagues know where I am.

Mm-hm.

What do you want?

What do I want?

To spare Christian.

Well, I'm afraid we're past that point.

Should I speak to your mother?

[laughs] Why do you want to do that?

She knows how much a woman loves her son.

However much he may disappoint.

Hmm.

You don't care for Christian.

If you did, you would have got him out long ago.

[Davor] I wouldn't have exposed my son to so much danger.

Easy to say when you don't have one.

Does Dubravka know you were raped?

I deal with my business my own way.

I think you should leave.

Christian chose his own path.

No, no, no, no.

You sacrificed Christian for your self-interest.

You and that Sean Hardacre, both of you.

He won't suffer.

On my family's honor.

[Davor] It's the best I can do.

[Davor] Now, fuck off.

He's alive.

Christian is alive.

They don't know where he is.

There's only one way to save him.

[sighs] You're in the clear.

Good.

The home office is convinced it's terror-related.

Kane's starting to come round.

Hmm.

And what about Hannah Laing?

Suspended.

And being investigated.

By yours truly.

I'm acting head of department now.

You just need to lie low for a while.

And then... One last thing to take care of.

I just want you to know that Fran wasn't working with us.

You shouldn't be here.

She was following her own lead.

She contacted Bianca Mimica.

You should go.

Check Fran's files.

[sighs] [phone vibrates] Hello?

[Christian] It's me.

I escaped.

But I'm fine.

Well, thank God.

[Christian] Are you okay?

It's so good to hear your voice.

[Christian] How's Billy?

He's...

He's alive.

[Christian] And the others?

[Christian] I'm scared.

It's okay to be scared.

But you've got to be strong, too.

We're going to beat these fuckers.

[Christian] How can we?

I'm going to tell you how.

[exciting music] [Davor] You should take a right turn.

Just go.

Go, go, go.

That should be everything you need.

It's from your father.

He was always good for one thing.

My boy.

You have to go.

[ominous music] [Zvonomir] Where is the cop?

Come on!

Psst.

He's running!

[gunshots] Christian!

-[gunshot] -[Christian grunts] -[gunshots] -[Christian grunts] [gunshot] [ominous music] [gunshot] [gunshot] Christian!

You okay?

[Christian coughs] [grunts] [pants] [sighs] [Christian pants] Billy!

Billy!

[Christian] Davor!

Davor!

[gunshot] [gunshot] [grunts] [pants] [Hannah] Davor!

Davor!

Drop your weapon!

Drop it!

-[grunts] -[gunshots] [grunts] [sad music] You should go.

Do you know where you're heading?

No.

Actually, don't tell me.

No postcards.

No email.

Nothing.

Quepos, in Costa Rica.

Any word?

They're still not answering.

And Bianca?

I'm sorry.

[Jovan] What do we do?

We open up.

As usual.

Go on.

Get started.

I found this amongst Fran's things.

Along with proof of Sean's torture that I'm not going to share.

Took me a while to figure out who everyone was.

But I think I got there in the end.

I can see why you would trust your contact implicitly.

And why you wouldn't want to risk identifying him.

No.

This stays between you and me.

Do you know who the leak is?

I've no idea.

You're reinstated.

Thank you.

[Kane] You'll join the investigation -into the boathouse massacre.

-Yes, sir.

[Kane] But your real assignment?

Find the bastard who betrayed us.

[suspenseful music] [hopeful music] Hi.

[Bianca laughs]
