from the start and contains strong language and graphic violent scenes

This is how you escaped the QEII building, after you assassinated Isaac Turner. Yes.

What's your real name? I'm Captain William Walker, United Kingdom Special Forces.

The Increment?

Is Simon your commanding officer? You could say that.

I'm here to see Simon.

Is he here? Right in front of you.

You're using AI to support Ops?

Support, map,

execute, command.

Why did you fall out of favour with your squadron?

Argh! Back there at the warehouse,

I was under duress, vulnerable to compromise.

Who do you work for?

Simon flicked my kill switch. LONG BEEP

We need a new head of SO15.

Ah. We're going to have to go back to Rachel Carey

with our tail between our legs.

NEWS REPORT: The truth about Correction may finally be coming.

When did you first become aware of the Correction programme?

There are files in the archive on James Whitlock.

About our former friend, MI5.

Gemma Garland's coming in?

Give her access to the archives.

You got nothing on me in Abbot's Cliff.

No bullets because there weren't any bullets to find.

According to SOCOs, Whitlock's rifle was not loaded.

Panic over. Figured out how to have the podium on the right

and the Carey Cam in the middle.

My team know what they're doing.

Why compromise the tech when you can compromise the technicians?

Isaac Turner was not my only target.

They were never planning to kill you, Rachel.

They were planning to kill your reputation.

Who knows how long I've got left?

I'll spend it helping you expose my squadron for what they've become.

You brought down Correction.

If anyone can bring down the Increment, it's you.

Right, who wants to go first?

Well, as it's my gaff...

Was killing the Home Secretary your primary objective

or was there more to the operation?

There's always more to the operation.

You might need to wind in your expectations.

He only knows one layer of the operation -

his.

How useful an asset is he, Rachel?

If I had to guess...

..why Turner was targeted...

..the algorithm predicted he'd start a war with Russia if he became PM.

Or not start a war with Russia.

Whichever wasn't cool with the complex at the time.

The complex?

Military...

..industrial.

I want to know why they're trying to frame Whitlock.

There's plenty more credible gun nuts out there. Why choose him?

I wish I knew.

As Rachel will tell you...

Yeah, you're a cog. We know.

Forgive me, but would it not be quicker

for you to brief us about James Whitlock?

My thoughts exactly. Your department, your watch.

Not that you'd know it from the report.

The heavily redacted report.

Got to be worse than the shit you've got on me.

There's no danger of that, Rachel.

No danger at all.

It's your past case, it's your problem.

As long as it doesn't get in the way of mine.

Whatever it is, we are releasing Whitlock tomorrow.

Your friend doesn't like me.

My number is the only one saved, in case you need to reach me.

Is there, erm, anyone you'd like us to contact on your behalf?

You mentioned your...

..girls? Or was that just...?

Part of the legend.

Commander Noah Pierson is married with two daughters.

Dogs? Dogs, cats, goldfish...

The dream.

And William Walker?

Never found the time.

Helping expose the Increment,

you're doing a good thing, William.

Enough to atone for all the shitty things?

Someone will come and bring you the basic essentials in the morning.

Toiletries, clothes...

That bad?

None of us smells like roses.

Didn't like to say.

Hey...

What happens in the tunnels, stays in the tunnels.

Get some sleep.

No.

No?

I'm sorry, sir.

I can't accept the position.

What do you want, Rachel?

Autonomy.

I want the freedom to run my investigations as I see fit.

I want security clearance sign-off.

Just wait here, please.

I want operational control of SO15 without oversight.

Anything else?

Yes.

Keeping corruption out of this department will take commitment.

I'll need a five-year contract, minimum.

Five years? One year... Five years, non-negotiable.

Three. Done.

Finally... There's more? My title.

This department needs a commander, not an acting one.

I'm surprised you haven't asked for my parking space.

I wouldn't take anything for granted, sir.

NEWS REPORT: In breaking news,

the man arrested on suspicion of the murder

of British Home Secretary Isaac Turner has been released on bail.

Our political correspondent, Natasha Hayes, is in Central London.

Natasha?

Khadija, good morning. I'm here outside Counter Terrorism Command

where Mr Whitlock is expected to be released from custody shortly.

Police say they are following

a new and highly significant lead in the investigation

into the killing of Home Secretary Isaac Turner,

which has shocked not just the nation, but the world.

In releasing Whitlock,

the police now have a lot of questions to answer...

Right, keep your head down, Jamie. Keep moving.

Oh, with me. With me. Mr Whitlock, if you didn't kill

the Home Secretary, who did?

Yeah, listen. This ain't the first time police have stitched me up.

This time I'm going to sue them for defamation of character.

And if I find out that firearms officers have hurt my kids,

or my dog, I'll be taking them to court.

They've harassed me for years.

Stand by for executive action.

Sir.

With Isaac Turner's tragic and untimely passing,

the public inquiry he called for has been denied his testimony.

Now, I believe the best way to honour Mr Turner

is to persist with this inquiry without delay and get to the truth.

Hear, hear, Lord Frederickson. I wouldn't change a word of that.

Isaac and I may have had our differences...

Sir Rowan Gill,

Isaac Turner's predecessor,

you served as British Home Secretary for three and a half years...

..a period in which the Home Office suffered its worst

reputational drubbing since its inception.

I hope you'll be more forthcoming

than your police counterparts have been thus far.

Ask me anything you wish, Lord Frederickson,

and I shall answer to the best of my ability...

You will answer to the best of your knowledge, Sir Rowan.

I stand corrected. MUTTERING

When did you first become aware of deepfake evidence tampering,

Sir Rowan? Do you mean Correction?

Erm...

About a week into the job.

APPLAUSE

Congratulations, Commander Carey!

Well done, Rachel!

Ma'am? I've got a lot to brief you on.

Yes, ma'am. Yeah, I'll rally the troops.

No. Just you two.

Ma'am...

We should've given you the benefit of the doubt.

Yeah. Sorry is what we're trying to say.

It's understandable, given the evidence to the contrary.

Coal Drops Yard.

Rachel? What is it?

The inquiry...

It's blowing up.

TV: Once the footage was corrected it was planted for somebody to find.

An unsuspecting lower-ranking detective, typically.

You know, a cog.

I'm interested in those who were well aware of what they were doing.

Who else had knowledge of the Correction programme?

I only ever met one individual directly involved with

the Correction programme. One operative? From the police?

And this is where it gets sticky.

"Sticky"?

Well, they were in the police,

but they were also working for, erm, a different entity.

A spy? Uh, a plant?

Again, sticky.

To be clear, Sir Rowan, you are talking about someone

who posed as a police detective, but worked for British intelligence?

And to be clear, Lord Frederickson,

I am talking about the woman who ran the Correction programme.

How many female officers in SO15? 200?

Three? Tash? Get your crew down to Parliament Square.

I need you to get together an OB from the inquiry.

The mystery female spy? On it. Let's go.

You say she ran the programme. Can you give me her name?

Not without breaching the Official Secrets Act.

Then invite her to make herself available to this committee

at the earliest opportunity.

And I would advise her this public inquiry has a mandate

to compel witnesses to testify under oath.

You must do as you see fit, Lord Frederickson.

However, I would like to make clear that I have nothing but respect

for the individual in question.

A profoundly loyal spy,

who has spent her life defending her country, till the end.

Now, a spy of such integrity, it's like a...a rare or precious stone.

An emerald...

..or a gem.

"Gem"?

MOBILE VIBRATES

DI Latif has command of the room.

Khadija?

Is it her?

The spook you brought sniffing around our studios last year?

DSU Garland?

Gemma Garland, wasn't it?

Rowan Gill practically said it.

Friends, Khadija?

Friends? Yeah, of course!

Look, obviously, I can't confirm or deny,

and obviously this is off the record.

Gemma Garland is being set up.

I thought you'd be glad to see her testify.

Isn't that what you wanted? Well, not in this way.

There is no way that Rowan Gill

was the only government minister involved,

and there is no way that those higher up in MI5

did not know about it.

Members of the British state trying to bury the deepfake scandal.

That is the story, Khadija.

Not a bad headline.

Congrats on the top job, by the way.

But don't start getting ideas above your station.

I'll decide what the story is.

Khadija... DISCONNECT BEEPS

SHE SIGHS It's her.

But it's off the record.

Ah, Rachel! Can I have a moment? No.

I think you might find it relevant...

..as someone who is interested in stamping out corruption.

You...you were right.

Pierson's security vetting was...irregular.

Yates leant on me to bend the rules. I was told it was a timescale issue.

I'm going to go to the PCC with everything I've got.

Are you with me?

What have you got?

A time-line of Pierson's compromised security vetting,

video files of his suspected deepfake interview.

Copy everything,

but we need to aim higher than the Police Complaints Commission.

I want arrests.

Are you with me?

Commander.

Why are you doing this to me?

I did everything you asked.

You promised me that would be it!

You said I'd never hear from you again.

Stuff happens, Paige.

Things change. We adapt and evolve.

Yeah, but you just... You can't message me here!

Do you know how many fucking cameras there are in this place?!

Can you talk? I'm in the toilets.

Use the flush.

What? Sound cover.

FLUSHING

Just... Do you know how bad this is for my mental health?

Deep breaths, Paige. In and out.

It'll all be over soon.

One more ask... You can't make me.

You've...you've got nothing on me.

You deleted it.

Yeah, it's the weirdest thing.

I thought I had deleted it and then it just...

..it just popped up again on my desktop. Fuck you, Tasha.

I wonder how it would go down as a screensaver?

What do you want?

I need you to fast-track a freedom of information request.

Just that? That...that's it?

That's it.

Then I'll delete it.

Do you promise?

After this, you'll never hear from me again.

DISCONNECT BEEPS

Do you have anything you wish to add to your testimony, Sir Rowan?

Yes, I do have something.

I have been transparent with you, Lord Frederickson, as I have

always been a staunch advocate of government accountability.

But I caution you to wait until you've heard the story from both

sides, before deciding whether any serious wrongdoing has been done.

Bollocks. Well, how much more do you need to hear?

He's throwing you under the bus, Gemma!

Question is, what are you going to do about it?

He's already given them "Female detective from SO15".

How long before...? Gemma!

NEWS REPORT: We can now confirm the identity of the MI5 spy

as DSU Gemma Garland.

It is believed that Gemma Garland

posed as a high ranking police officer for several years...

Excuse me. ..working at the heart of Counter Terrorism Command

and orchestrating the deepfake...

Abigail? Are you free?

No.

I'm just round the corner from your work. Are you going to the vigil?

The what? Yeah, the vigil.

For Isaac Turner? There's a load of us going.

I think Isaac Turner would rather I finish solving his murder

than sit around singing Kumbaya, Abigail.

It's not going to be like that. LINE CRACKLES

Abi? They're having a gospel choir and everyone's lighting candles.

It's going to be really sweet...

Abi, I'm going to have to call you back, all right?

MESSAGE ALERT

Fuck!

GUNSHOT

Ma'am, get down! Stay down!

Ma'am! Stay down!

TYRES SCREECH

Ma'am, do not exit the...

GUNSHOTS

MACHINE GUN FIRE

RATTLING

DOORS THUD

ENGINE STARTS

You know you're walking into a trap?

Yes.

It does seem that way.

Those Whitlock files...

The ones we destroyed?

Those were the originals?

No copies, no insurance, Gemma?

Do you want to strip search me?

You eaten in the last 24 hours?

Two slices of dry toast and a banana.

Oh...

There's a tray of vegan lasagne in the freezer.

Should be enough to feed a hungry safe house. I'll save some for you.

Unless you won't be back for supper?

They can't compel you to testify if you're out the country.

You know all the tricks, Danny.

You don't have to make it easy for them, Gem. I didn't.

Yes.

I saw what you did.

Bye, Danny.

Does anyone have eyes on Rachel Carey?

She said she'd give me regular updates.

Can someone try contacting her?

Anyone?

Commander Carey.

It's an honour.

And you are?

Short on time.

I thought I'd take the opportunity to meet you face-to-face.

There may not be another one.

You've become rather famous in our operations room.

You're quite the curiosity.

Simon can't figure you out at all.

Our data knows us better than we know ourselves, apparently,

but not your data.

You're an anomaly, Rachel.

A kink in the slinky...

..yet to be beaten out.

Do you know how easy it was to compromise your colleagues?

Remind me, who was buying diamorphine on the dark web?

DCI Kendricks, sir.

Buys it for his 22-year-old daughter.

It's cleaner than the street heroin that

put her on life support last year,

before Bank of Dad started funding her habit.

Don't judge the man too harshly.

What father doesn't want the best for his daughter?

Others folded for less.

Who else in my department have you blackmailed?

Whoa... Lots of cogs in that machine.

Besides Commissioner Yates.

There's many moving parts to that mission.

Angela Stilton, comms.

The timing, the staging...

The position of the camera.

It's not that we're short on intel.

Far from it. We know that you buy two litres of whisky per month,

nine bottles of red wine.

We know that you downloaded a dating app

but are yet to activate your account.

We know that you took out a personal loan seven months ago

for oocyte cryopreservation, or egg-freezing.

It's not so much the data Simon's struggling with.

It's...it's...it's the analysis.

Have you tried turning him off and on?

Ha!

As a matter of fact, we're going to try something rather more familiar.

If Simon can't predict you,

we'll find another way to get through to you.

Look who dropped by to say hello.

Come on, Rachel.

Don't you recognise your own sister?

That's not my sister.

Abigail Carey, activist and podcaster.

That's a deepfake.

Are you sure?

Famously difficult to verify, I understand.

Let me to speak to her.

No-one's taken your phone.

Give her a try.

PHONE RINGING

Hello?

Abi?

Rachel! Where are you?

Abi, I need you to listen.

Why are you speaking like that?

Speaking like what? So serious.

You're freaking me out!

Because this is serious, Abigail.

Look at the camera.

Where did we go on our first family holiday together?

When I first moved to London.

What? I don't know.

Think, Abigail.

Think.

Ramsgate? No...

Margate?

This is stressing me out so much! What if I get it wrong?

Rachel? Yeah, I'm here.

INTERFERENCE DISTORTED: Rachel? You there?

Yeah, Abi, I'm here. I can hear you. Abi?

The next phone call you make will be to Counter Terrorism Command.

You will tell your officers to drag James Whitlock

back into police custody

and charge him for the murder of Isaac Turner.

And if I don't?

Are you still sure this is a deepfake?

Or is that your sister Abigail under that hood...

..gun to the head?

PHONE RINGING

Tom, what did you used to call Garland when she wore that coat?

What, the fake fur?

Cruella Rimington.

Tom, this call isn't secure.

I know you've been blackmailed

and I know Veritas is compromised.

I'm not interested in excuses or denials, I just need you to listen.

Uh, yes, ma'am.

If Ops Room One is fit for purpose,

run facial rec on Abigail Carey, my sister.

Ma'am? Tom? INTERFERENCE

DISTORTED: Ma'am? Tom?

Comms check, Kilo One. Now!

Control to Kilo One - do you read? What's the concern?

Kilo One, do you read?

Commander Carey's under duress. Run facial rec on Abigail Carey.

Wow!

Poor Abi.

If you've got Abigail, let me see her.

Take me to her.

Make me watch with my own eyes.

Sorry.

That's not part of the plan.

Control, all units.

Sentinel One is down. Repeat, Sentinel One is down.

Commander's vehicle? You still tracking Rachel's phone?

I've been trying to tell you.

What do you know about it? She's in trouble. No shit.

Phone is out of range.

Last known location, Rotherhithe Tunnel.

Repeat, Rotherhithe Tunnel.

Take me with you.

I can help.

You fill out the risk assessment, mate.

We'll see you in about a month, yeah?

Your boys aren't going to find her, Danny.

And what hope have they got against E-Squadron if they do?

All I need is my handset and a CR-2302.

A what? It's a battery.

And maybe a little help installing it.

Not a bleeding chance.

If Rachel Carey's been taken by my squadron, I know where she is.

Where? The Kingsway Exchange.

But if you don't know the tunnels like I do, you'll never find her.

Danny?

You haven't seen what he can do.

Yes, I have.

I happen to owe Rachel Carey my life.

Least I can do is risk it trying to save hers,

and chances are...

..that's what it'll take.

When was the last time you made a decision?

I beg your pardon?

For yourself, I mean.

Not Simon.

Go on, try it.

Take me to Abigail.

Put the data down and start acting like a commanding officer

and not a cog.

You can't do it, can you? SHE LAUGHS

You can't scratch your nose unless Simon fucking says.

Decorated military officers,

taking orders from an algorithm.

It's pathetic.

Well, I've taken orders from schoolboys

straight out of Sandhurst.

I'll take my chances with AI.

Clear. Wait. No. No. Wait.

No! Clear for executive action. No, no, no. Wait, wait, wait. Abi!

Wait! Abi! No, wait! Wait!

Fuck...

Was it her?

Guard!

Was it her? Was it fucking her?!

Was it her?!

GRUNTING

DEVICE BEEPS

Wizard, you beauty!

Thank you.

Could you please state your name?

Er, yes. My name... Would you mind speaking up, please?

My name...

..is Jacqueline Goldcross.

I served in the security service MI5 for 36 years.

For the last ten of those years,

I ran a deep cover operation inside SO15,

under the name of Detective Superintendent Gemma Garland.

What was the goal of the operation?

MI5 had failed to stop a succession of terrorist attacks.

The public were tired of excuses.

We needed to find a way to stop violent extremists

before they could act.
