Joe?
Did you get him down?
Joe?
He...
He fell, Abby.
He went under the train.
Are you sure?
Yeah, I'm sure.
I'm sorry.
- I should've... - Hey.
You haven't anything to be sorry about.
- I'm sorry. - Okay, listen...
Okay?
This is on whoever's behind this.
Yeah.
I might be able to help with that.
What?
I've got something. A USB.
It's from the woman with the baby.
Or not. I dunno.
She gave it to the reporter in the hotel.
And what did the reporter say?
She said she was just brought on here for publicity.
I think she's been tweeting some stuff out about us.
She's not involved.
Okay, can you go to the office and connect the phone back up?
- Yeah. - And then the USB to the phone,
and we should be able to read it.
Yeah, I'll try.
Look. It's alive.
Signals, points.
Look.
They've taken complete control of the network now.
None of that is us anymore?
All of it is them?
We might not have been driving the train before,
but at least we used to be in charge of where it went.
We've got it.
- It's downloading? - Er, no.
Looks like we've got the whole thing.
It's just on one file.
17kb.
Scanning for malware...
Clear.
The entire UK rail network
is now just a model railway in someone's attic.
And now we know whose.
*CREDITS*
_
Abby.
No, sorry, this is UCH maternity.
Erm, is that Mr Geoghan?
- Er... - Sky has asked if I would give you a call.
She's sorry she can't speak to you herself right now,
but she's had a hard old time, you know?
Yeah, yeah.
She just wants you to know, though,
she wanted me to tell you there's nothing to worry about now.
She's okay.
And she's not the only one.
Are yous alright?
I'm delighted to tell you that
your daughter was born at 25 minutes past midnight this morning.
And she's a fighter, just like her mum.
So I'm told, like her dad too.
By the time we got to the door, he'd...
gone under.
We should've got off when the train stopped.
As soon as it stopped.
Right, and what have I been saying?
Do you know what? I quit.
Where are we?
Bentham Line. North-west of Leeds.
- Yas, come on. - No, Billy, no.
Okay? I don't work on this anymore, right? I don't work here.
Well, you've got zero chance of getting a tip from me anyway.
Okay, look...
Just... Don't touch me.
Okay. Okay.
See, if you start filming again,
if you do anything remotely approaching filming again...
This has to be documented.
- After what you've done? - I told you, I haven't done anything.
Alright then, keep going.
Keep going and see what happens. Come on! Keep going!
Don't you dare speak to her like that!
Don't you tell me what I can say
- and what I can do... - Just shut the fuck up!
I can say whatever I want to say
and whatever I want to do...
Stop!
There is nothing, almost nothing,
to suggest that anyone here had anything to do with this.
Whatever he says, or they say.
A phone, another phone that works, that's it.
Someone keeping that to themselves for whatever reason
does not mean that they were the ones on their hands and knees
installing some little device through there, does it?
That they've got a whole toolkit.
They're two separate things.
Okay, then.
If it's you,
if you're the one with a phone that's still working,
a satellite one, huh?
Trying to...
Can you speak up now, please? Mm?
Huh?
Well, speak.
Come on.
Speak.
Speak now.
Hey, hey!
Hey! That's my medication!
Get your hands off my bag! What are you doing?
- They were right. - Who?
The Americans. It's the Blue Blockade Group, the BBG.
- Who are they? - This is their manifesto.
Claiming responsibility?
Yeah.
'Every action creates a reaction.
We reject and condemn the UK government's
continuing attempts to intervene in the affairs
of the sovereign nations of the Middle East'.
Saying it's a 'demonstration of their commitment
to confronting Western interference'.
They're a group based to of Tehran.
It's a nice sanction-busting ransom demand.
Who's gonna be the one to tell them that nobody's actually gonna pay it though?
Well, this isn't just a hack anymore.
It's an act of war.
Ma'am, could I, erm...
You don't think that this is connected to...
What?
To Mashhad, ma'am.
I don't know what to think.
But I do know there are people I have to speak to.
A lot of them.
- What's the next station? - Leeds.
Okay, we need more intel on them.
Zed, Leon, where's the police helicopter?
- Yeah, on it. - Where we at?
Attribution's closing in on a location
hit from the command-and-control traffic.
We should be able to confirm the source soon.
Okay, so we're now thinking Tehran.
We're now knowing Tehran.
- Can we confirm? - Mm-hmm.
- Pev? Tobi. - Yeah.
I think we almost have enough of the attack code parsed.
to run it through the system.
Great. I know these guys. They always recycle their code.
We get a match for a section,
there's a good chance we'll be able to find out who wrote it,
close in on someone with form in Tehran,
and then fill in the blanks for the rest.
Yeah? Abby?
Yeah.
Do it.
Joe?
Joe.
She's alright, the oil rigger's wife.
So is the baby.
What was his name?
His first name.
Sam, Dan, David?
Joe?
I didn't say anything to him.
Not at first.
Do you know why?
No.
It's cos I'm a fucking man.
I was hoping it would sort itself without the need for an actual conversation.
We just... we do what we do, don't we?
Is that supposed to make me feel better?
Well, that's why I'm talking to you.
Because you're doing...
what you were always gonna do.
Same as when you saw that bag get snatched.
Look, there are three types of people in the world right now.
People who intervene, people who don't, and...
people who just film and share it.
I wish I was one of the last two.
I'm glad you're not.
It's not looking great through there.
I think the accountant's doing what he was always gonna do.
What do you mean?
He's trying to search through everyone's bags.
Look, he's... he's scared.
They're all scared.
Wouldn't hold it against them.
They need a leader. Eleven of them do.
Ten.
Sorry.
Who are you, Abby?
What do you mean?
How did you come to...
be there doing that job?
What got you into all this?
Joe, we could spend all night talking.
All year, and...
you're still not gonna get that stuff out of me, because...
it doesn't matter, does it?
What we're like outside of all this.
What matters is that we help each other.
You say that, but...
I do know that you like Kate Nash.
About 15 years ago.
So, you're probably the same age as me.
I know that.
Are you gonna go back out there or...
As it's you.
Right, here come the cavalry.
Finally!
- Abby. - Yeah.
We have got a location hit.
Tehran?
Johannesburg.
Well, it is a hack-for-hire shop these days, isn't it?
Looks like our Iranian group are outsourcing.
- That's not your property. - We need to know what's in here.
- Let it go. - I can vouch for her.
- Can you? - We can vouch for each other.
There's more than one Sophie, eh.
What's that supposed to mean?
It means she's got a problem with the drink.
It means I am an alcoholic.
Alright?
And I'm three years sober.
Is that you? Happy now?
Oh, is it all ancient history?
Saint Sophie now, eh?
Yeah, I'm trying.
You nearly bankrupted my son.
Fraser, I'm so sorry.
I'm so sorry that your wee golden child has such poor taste
in life partners but hey, we can't all be
as silently long suffering as your Jessie now, can we?
Don't you bring my wife into this.
- Give us that bag... - Hey!
Come on! Oh, here he is!
Here he is, everything's gonna be alright now!
Mate, will you stop being a prick for five minutes, please?
I'm not your mate.
Yeah, no chance having your friend request accepted.
Alright, that'll do.
Joe, is everything alright in there?
No, it isn't!
Can I please just have that phone?
Guys, guys, look what just happened to the oil rigger, yeah?
We're stuck on here, right, together,
whether we like it or not.
So, for the good of all of us, let's just take a breath.
Get down!
- Get down! Get down! - Joe? Joe!
What is happening?
Did someone just shoot at the train?
- No. - I'm gonna say yes.
I'm glad you moved this time.
Joe.
Who's shooting at us, Abby?
- I have no idea. - Oh, God.
Right, are you all okay, yeah? Everyone?
Everyone? Good?
Ma'am, shots have been fired at the train!
Indeed.
You... you know?
We... We have armed hostiles on the ground.
We need our own people there.
This isn't just a cyber-attack anymore, this is...
Abby.
That wasn't a hostile group.
That was us.
What?
Do you smell smoke?
Shit.
They've struck the electrics.
We can't let it get to the engine.
Remember what they did to the goods train at Gretna.
The fire door should hold it for a while.
Stay back.
Stay back, stay in the lounge.
Our objective was to shoot out the fuel tank
and drain the diesel before the train gets to Leeds
and goes off to God knows where.
What, without telling anyone on board?
If someone on board is involved,
how could we be sure that they wouldn't respond?
That the train wouldn't?
But without even telling me?
Abby, there are so many things about tonight I can't tell you.
Excuse me? No, sorry, sorry, what does that even mean?
The moment it came off your loop
you couldn't possibly think that every other agency involved
- were just going to sit back. - We could have killed them.
They're on a train being driven by a group with a grudge
alongside a passenger who appears to be armed and involved
on a network that they now control, not us,
going so fast that the threat of derailment is constant.
We do not pose the threat.
Whose idea was this?
Well, they all come running back in the end.
Do you have something showing the speed of the train in there, Nicola?
- We do. - Is it slowing down?
Doesn't appear to be.
- Did you get the tank? - Uncertain.
Erm, it was a fairly hastily assembled team, unsurprisingly
and there was a change of speed suddenly
which made things very difficult.
Yeah, it would've been nice to know.
- Yeah. - Yeah.
Well, maybe I'm not the guy you wanna switch off.
So?
What are we dealing with?
Have the Iranians taken this IRL?
No.
No, it was friendly fire.
Our guys.
Above our pay grades, apparently.
Pev, can you and Zed dig into
the known proxies used by that hack-for-hire outfit?
- Yeah. - And, Tobi, dig into the new system hacks,
see if you can replicate the IP match.
Erm... What are you doing?
Didn't you just hear?
Yeah, but we know who we're dealing with now
and I've currently got multiple code libraries up and running
trying to follow the trail.
I mean, do we?
What?
Like, really know?
Well, yeah. They said it's them.
Yeah, on a USB given to a reporter
filled with stuff that could've been copied and pasted from anywhere.
Okay, well, why would anyone...
I dunno. Maybe someone out there wants us to think it's them.
Come on, why would an elite Iranian hacking group
be outsourcing cyber warfare?
Because they're camouflaging?
They're bouncing traffic off a blacklist IP to cover their trail, Abby.
What's the point in camouflaging
when they're waving their arms in the air shouting,
"Hey, guys, it's us, over here!"
We should be putting the attribution team
onto the code analysis that I've been doing. I need the help.
Look, I'm not saying that it isn't them.
I'm just saying that we still don't know that it is.
And until we get this verified independently,
I don't want us running down paths that could take us
in entirely the wrong direction.
Hello!
Is someone in there?
Joe!
_
Fuck.
You got something?
Er... No, no, it's nothing.
- Mouse! - Joe!
I'm coming! Stay right back!
Put this over your mouth.
There you go. Yeah? Come here.
Stay close to me, alright?
Come on.
Come on!
Help!
Shit!
Help!
Mouse.
Help!
The Johannesburg connection to the network attack checks out, Abs.
Traffic's all going one way.
Whether the Iranian group's behind this or not,
no one's making it look like all the activity's coming out of South Africa.
It is actually coming out of South Africa.
Okay. I need to take this to Miller.
Er, Abigail.
Yeah?
I think the train is on fire.
What?
Those morons must have hit the electrics.
There's nothing moronic about trying to actively save lives
rather than just sitting there pressing return.
What's this twat's name again?
Have we contacted emergency services?
Nearest airborne response team is at Leeds-Bradford.
They're still ten minutes out.
It'll have been worth it if it stops that train.
It hasn't made a bit of difference.
You haven't hit the tank, you've hit everything else.
If the fire gets to the engine, it's over.
Joe!
- Hey! - Joe, Joe.
Mouse!
Joe! I've got you! Joe, are you okay? I've got you!
Come on!
We've got you!
Mouse! Come on!
It's okay. It's alright.
Alpha-Lima Seven, this is November-Charlie One.
Are you still in contact with your team? Over.
November-Charlie One, this is Alpha-Lima Seven.
We are, and they believe that the fire is now under control. Over.
Thank you, Alpha-Lima. Out.
Where is the contact with the train?
Nothing from just after the shots were fired, ma'am.
So, your man's gone AWOL?
I'm gonna take a wild guess and say he's a bit busy putting out fires.
Aren't we all?
Get that down, you.
It's done.
Thanks.
It's a bit of a mess in there.
It's okay. The ransom will be paid soon.
Someone will pay it, and it'll be okay.
Thanks, guys. Really.
That's alright.
Abby.
Hey. I recognise that voice.
I don't know how. I feel like I've aged.
Yeah, you're telling me.
Hey, erm...
look, the shots that were fired were from our side.
The police. They were attempting to drain the diesel.
They don't appear to have been successful.
What?
It was the police shooting at the diesel tank.
Fucking clowns.
Did they succeed?
In stopping us? No.
In making me and him require years of therapy, probably.
Did you put it out?
Sorry?
Was it you... who put it out?
No.
No, it was these guys.
Got Leeds coming up.
Cross country. Midland, East Coast,
Mainline, they all cross over here.
- Sorry, babe. - Heart of Britain overnight service
to London Euston
is back on track. Back on track.
They're heading south.
Speeding up again.
So it's still going to Euston?
Maybe.
But how do you stop something
when you've no idea which route it's gonna take?
You alright, pal?
Get some rest, eh?
Look, I don't know what's going on here, any more than anyone else.
But I don't think shouting and screaming at each other is gonna help, is it?
Agreed.
When we get off, and we will,
we're gonna be the only people who understand what this was like.
Alright?
And I for one don't know most of your names.
Don't even know what you're doing on here.
Do any of you know the oil rigger's name?
Alright, I guess I'll start then.
Hello. My name is Joe.
Oof.
I've been in this meeting before.
I'm going home to visit my boy.
He's the only one I'm still in touch with since I've been away.
He sent me a message that worried me.
Worried me a lot.
Sometimes a call or a screen just isn't enough, is it?
That's... That's why I'm on here.
Alright, who's next?
Spin the bottle?
Whoa, whoa, whoa!
There's still some in that.
Well, is this off the record?
I'm assuming that's addressed to me?
- You assume right. - Oh, don't worry about her.
You can trust her. She would never, ever lie.
Okay.
Okay. Well, look, I wasn't supposed to be on here.
I'm not here by choice.
I'm on here because my special adviser persuaded me...
and believe me, she is never gonna hear the end of that.
She persuaded me that, erm...
a night without much sleep would be worth it
for the tweetable image at the end.
You know, and I have to say I disagree.
Okay, that's it.
Just get in.
You know I like a secret pow-wow
but this isn't the best time to...
Right.
Do things seem right to you?
- What do you mean? - Miller?
Yes. Yeah, I just feel like something's going on.
Like everybody knows more than us.
Me! Like Miller, definitely, she said so herself.
But Saj now, too.
Miller's always gonna know more, love.
She can't tonight.
How can she?
How can we know that we're doing the right thing,
everything we can, when we only see half the picture?
It's a live-op, Abigail, wires get crossed.
Look, you have always taught me that our job
is to assume worst-case scenario and act accordingly.
- Mm-mm. - So?
What do you want to do?
I think we should hack Miller.
Erm...
I'm obviously here because I work here.
Hey, slow down.
So, Billy?
Billy McLeod.
Just leave him.
Billy's alright.
It must be tough.
All those late nights.
We are just... babysitters.
Sounds like it'd push anyone.
Overworked, underpaid.
I for one wouldn't blame you
- for getting involved in... - No.
She's got a point. You two were the only ones that had access.
All I've done is try to make sure everyone is comfortable.
What, you think I went in there and wired up some little device?
They barely give us training on how to work the coffee machine.
Well, you would say that, wouldn't you?
Abby, this is not possible.
Well, it may be possible, but it's definitely inadvisable.
I built the guard dog to that particular house.
Walk through the gate uninvited and it'll take your arm off.
She's at the door.
What are you actually doing?
Going fishing.
She... She's got it.
Come on.
Click the link.
Abby, she's the head of GCHQ, she won't click the link.
I think she just clicked the link.
Sack the guard dog.
- Are you in? - Uh-huh.
She's actually typing, right now.
- We are watching her type. - _
- Abby. - Leon.
Hey, can you just give us...
I don't think I can.
I don't think there's anything more important than this.
Er...
_
I've had a TA combing through all the CCTV
we pulled from Motherwell for the last two hours
to see if they could find anything at all.
- And? - You need to come have a look.
- Tobes, take over. - Yep.
Just...
Now, I checked it again and again to see if she was right.
Okay.
- What am I looking at? - The faces.
- What about them? - Just...
Just look.
Who the fuck is that?
There's someone else on the train.
Joe.
Abby, if you've been to the kebab house without me,
I am gonna be devo.
Listen.
- There's... one else... - Hello.
- on the train. - Abby, you're breaking up. Hang on, one minute.
Can you hear me?
Yeah, yeah. Can you hear me?
Yeah, I got you.
What did you say?
I said there's someone else on the train.
- What? - Yeah. I can't tell you anything more than that.
All I know is what I'm looking at.
What are you looking at?
CCTV from Motherwell
of the train after it's left the station
showing an unidentified male
looking out of the window of carriage E.
- E? - Yes, yeah.
Where the firearm was. We searched that.
Well, he must have still been on board there, somewhere.
Look, how are you gonna deal with this?
Same as everyone else.
Not well, Abby. Not well.
You don't know that the firearm that you found was the only one.
They may be armed.
Look, can you seal off the back of the train
while we work on getting an ID here?
Leon.
- Any news? - Nah.
Can I borrow your key card, please?
Why?
She wants me to check something at the other end.
No, no. It's alright. You stay here.
Everyone stay here, alright?
What is it?
Er... it's nothing. Leave it with me, alright?
Be right back.
I've been looking at common contacts, scanning for keywords.
Such as?
Iran. Railways.
- And? - Two things leap out.
There are a lot of references to something called 'Mashhad.'
Mashhad, yeah, it's a city in Iran.
It's a bit of a transportation hub.
Central to China's new Silk Road initiative.
Yeah, I'm familiar with Mashhad, thanks.
Over the last few weeks,
Miller has been in communication with one person more than anyone else.
The one government minister who happens to be on board.
What?
'Miller, we must talk'. Draycott.
'The decision has been made.' Miller.
'Then it must be unmade.' Draycott.
'You advise, we decide.' Miller.
'You need to understand the consequences of what you're suggesting.'
Yeah, we don't actually have any context for this.
Then let's get it.
Ma'am.
I need to discuss something with you. Urgently.
I think you just took my line.
It, er...
needs to be in private.
November-Charlie One, this is Alpha-Lima Seven. Over.
It does.
So I'm going to ask if you...
Abby?
He said not to go.
I've got a really bad feeling.
You didn't have one before?
Right, that's it.
Don't.
Holy shit.
Joe?
Abby. This is really not a good time.
Don't leave the cabin.
There's a man in the one next to you looking out into the corridor.
Right.
We really do need to speak, privately.
Yes, but not now.
Now.
You can come with me willingly and we can do this quietly
or we can make everyone out there aware of exactly
what you've done.
What is this?
- What have you told them? - Only what I found.
And what is that?
We're gonna have a sit-down, you and I,
and you're gonna have to come up with a very good reason
as to why the code used in this attack
happens to have been written by you.
Stop! Stop! Stop! Put your hands in the air!
- Hey, hey, hey! - Don't.
Shots fired, shots fired. We're pulling away.
