I'm picking up a very strange signal.
- What just happened? - We're losing electrical power.
Something's interfering with the systems.
- Officer Neal, run a full check. - Yes, sir.
Sir, I have an unidentified sonar reading
at bearing 2-0, designate Sierra 1-5-5.
It's some sort of...animal.
It can't be what's affecting the systems.
Sir, it's big and whatever it is, it's coming straight for us.
Sound the collision alarms!
Blow all tanks, take us up!
Planesman, give me full tilt!
I've looked into Prospero's property portfolio.
And?
Last year Philip bought a decommissioned power station.
Tell me what that's about.
Let me talk to Connor.
I don't think we can risk that.
But if he knew Helen was in any way involved with Philip,
he'd have nothing more to do with him.
You're letting your emotions cloud your judgement.
Oh, what, like you did with Emily?
- Emily was a low blow, sorry. - Forget about it.
Matt, I did some research.
I found out what happened to her.
Abby, I don't want to know.
Emily made her way home and that's all that matters, okay?
- Hey. - Hey.
I just want to finish something here quickly.
What are you working on?
I thought the dating calculator was all signed off.
Oh, this is um, this is...
one of those things I can't talk about.
Oh!
Sorry. Just... It's going to be good, though.
You are coming out with the team, though, right?
Yeah, of course. This is part of me job, too.
No, Connor, this is your other job.
Matt and I have had to cover for you lately.
People are starting to notice.
Do you know what? You're right.
I'm sorry, my bad. Okay.
I'm just going to...
Okay.
No running in the corridors!
Coordinates, 56, 21.9, 2, 48.8.
- That's a new one. - It's the middle of the North Sea.
Jess speaking.
It's for you. It's the Admiralty.
Lester.
There was a marine animal caught up on the bridge when we surfaced.
Could that have been what attacked your boat?
Too small. But it's not like any creature I've seen before.
- So where's the body now? - On board.
I'm not happy about this.
Captain, we've both got our jobs to do,
so let's just get ahead and do them, yeah?
And I don't care how "specialist" your weapons are,
they're not coming on board my boat.
If there's a need for firearms, we've a more than adequate armoury.
This is all scientific equipment, there's no weapons here.
Feel free to make an inspection if you want.
That won't be necessary.
Ah, an Upholder class electric/diesel boat.
How do you know that?
I, uh... I watch all the movies, don't I?
Das Boot, K19: The Widowmaker.
You know, death by drowning,
suffocation, radiation poisoning.
- Gentlemen. - Sir.
Thank you, Shaw.
These are great little SSKs.
As good as the Trafalgar class for sensors and armaments.
I thought we'd sold them all off.
We keep a couple for training exercises.
You know your submarines.
I was in the Royal Marines.
- Spent a bit of time underwater. - You were Army.
The Navy would have been my first choice.
Take her away, gentlemen. Forward one third.
Aye, Captain.
Sir.
- Give me 10 degrees, planesman. - Aye, Captain.
Connor.
Thanks.
Hey.
Can I just, uh... Can I ask a quick question?
Do you get seasick on submarines?
'Cause I've really got a tendency to...
Only on the surface. Underwater there's little sensation of movement.
That's good.
- Yeah. - A good thing.
This is Midshipman Leonard, my sonar officer.
This is Officer Nealand Officer Shaw.
Whatever you are here to do has been classified top secret
and I'm only permitted a skeleton crew.
Sorry about that, Captain,
you just get us to our station and we'll do our bit.
I've no engineers, no weapons operators
and no kitchen staff.
So "your bit" may well involve a mop and bucket in the galley.
We will do whatever it takes.
Captain, I would like to see the creature now, please.
- Sam, escort our visitors. - Aye, Captain.
Oh, sorry.
That hurt.
First thing you learn about life on board a submarine,
think small and thin.
- You'll be all right. - It's aft.
- What? - This way.
We're going to need access to your torpedo bay, too.
Why?
Captain, like I said, we've got a job to do, so just let us get it done
and you can drop us on shore in the morning, yeah?
There you go.
Now, what is that?
Some kind of theropod. A juvenile.
Thero-what?
Pod.
We think some species could swim, not extensively,
but enough to move between islands.
She must have been in the water, got sucked through the anomaly.
What's an anomaly?
Oh, that's classified.
But it's a dinosaur, right?
A real live dead dinosaur.
You were right the first time.
What, it's alive?
The North Sea is much colder than she's used to,
she's gone into a state of shock.
We have to keep her that way. Can we secure this freezer?
Well, there's an electrical lock, yeah.
Okay, good. Give me a hand.
She won't bite. Unless we don't get her in there fast enough.
Thank you.
So this torpedo is going to fire an electronic charge
onto the anomaly and impact.
It's basically a mobile underwater locking device.
- That's very clever. - Thank you very much.
There we go. Gently.
- Good work. - Listen, Matt, um...
I know I've not really been on my game lately,
it's just this work with Philip, it's... It's exciting and
I think it could be important.
I hope you understand.
I understand.
I know it must be difficult because
I know how Abby feels about Philip.
Tell me about it.
You know if you ever want to talk about anything
that you can't talk to Abby about, you can...
Tell your colleagues they're not to unlock the freezer
under any circumstances, okay?
Yes, sir. Ma'am.
Small theropod, a swimmer. Still alive.
What?
It's okay, she's secure, she's unconscious.
So how long till we get there?
Well, Captain's still charting the course,
it'll be a few hours at least.
- You should rest while you can. - Thanks.
It's good to go.
Flag Guard, Submarines, and his Commander are here.
Oh, perfect!
Admiral, welcome to the Anomaly Research Centre.
Mr Lester. The Minister briefed me about your little unit
several months ago. I hope your people know what they're doing.
I hope yours do, too.
If you'd like to step this way. We've established a command centre.
I need a dedicated line to the Admiralty
and another one to Whitehall.
You can establish secure comms to HMS Gartside, I presume?
Of course. They're scheduled to send us a signal
as soon as they reach the site of the anomaly.
HMS Gartside should be in position any time now.
Look, this is all rather routine for us these days,
why don't you get some sleep?
We'll alert you when the situation's resolved.
I'll take a pot of coffee.
Us, too. Mine with cream, no sugar.
How do you take yours, Jess?
Frothy, thanks very much, Admiral.
I understand your man intends to seal this anomaly
by firing a torpedo rewired to pass an electromagnetic charge through it.
- That's correct. - Why don't we just blow it up?
We do things differently in our little unit.
This man, Connor Temple,
he's an elite operative, of course?
Yes, yes indeed. The very highest calibre.
- Connor. - What?
You're doing it again.
I'm not doing anything, me feet are down.
This is brilliant. It's kind of like we're all camping out.
I thought you two would have had enough camping in your year in the Cretaceous.
Does anybody want to hear a ghost story?
No? What?
It's not like we've got anything to do until we get to the anomaly.
Fine.
- 7-31. - 7-3-1.
4-19.
We're almost on station, Captain.
All stop, two thirds.
Let's drift in there.
- Officer Neal, put some coffee on. - Yes, sir.
Sam, release the sonar array. Let's report our position.
Aye, Captain.
That's Emily's dagger.
Where did you find it?
It was in with the evidence from Ethan's flat.
Oh, you just happened to pick it up?
Well, you never know when you're gonna need a good knife.
Not 'cause it reminds you of her?
No.
Matt.
Matt, you need to know what happened to her.
Abby, you need to get some sleep.
Yes.
I've sent our position, sir. Anything else to add?
It's happening again.
- Electrical interference. - What the hell is that?
Oh!
- Hey. - Hey.
We've lost primary power and the Captain.
HMS Gartside, this is the ARC, are you receiving me? Over.
What just happened?
HMS Gartside transmitted their last position,
then the comms link went down when I tried to acknowledge.
They're not responding to the radio transmission.
I'll try a data uplink.
They're headed straight for the anomaly.
I'm getting nothing, they're completely out of contact.
We've suffered a major electrical failure,
the back-up system has kicked in, but the juice is needed primarily
for oxygen supply and emergency lighting.
Okay, where's Mr Neal?
He went to make coffee, I haven't seen him.
Mr Shaw, could you try to find Mr Neal? Thanks.
Sam, get me a damage assessment.
Abby, how is he?
It's bad concussion, he could be out for a while.
We have limited instrumentation, basic navigation
but something's jammed the propeller. Right now we're just drifting.
A big metal tube somewhere in the vicinity of a magnetised anomaly.
Anyone else see where this is going?
I'm picking up a very strange signal heading straight for us.
It's not heading for us.
We're heading for it.
Where's... Where's my submarine?
That's impossible.
We've gone from 150 feet of water to a depth of 120.
We've gone through the anomaly.
- Could be Jurassic. - Jurassic?
With no power or steering.
Well, unless everyone wants to get out and swim,
we'd better think of something fast.
Where in the hell are we? What just happened?
Just calm down, Officer, okay?
But the Jurassic era, that was like thousands of years ago.
Well, 200-244 million years ago, if you're going to be...
What? I'm just telling him.
We've just done some freaky time-travel thing,
that's what anomalies are. Who are you people?
We're the people that deal with this sort of thing
- and we're going to need your help. - I'm just a sonar officer.
Sam, your Senior Officer is disabled, that makes you the Ranking Officer.
Okay, the first thing we need to do is restore power.
Now, I need the ship's wiring plan, okay, Captain?
Good man.
This is the primary electrical grid. I have a hard copy.
Great. Can you show me the wire that leads to the mainframe power source?
It's this one.
It's a daisy chain that feeds through four junction boxes throughout the ship.
One, maybe more, fuses are fried.
Okay, this is good. Let's check the fuses, repair any damage.
What about the propeller?
We lost signal from the sonar array when we were attacked.
My guess is the cable's got trapped around the propeller.
I'll go. We've a mini submersible that I can deploy.
No, I need you here, you're the only person can start this ship again.
It takes two crew, one to steer and one to operate the cutting equipment.
- I'll come, then. - No, definitely need you here.
You need to sort this wiring out.
Let's get the Captain into a bunk. Me and Abby will go.
What about the creature that attacked us?
It could have followed us through the anomaly,
it could still be out there.
If we stay close to the sub, we might not register,
we might look like another large creature.
- Ready? - Let's go.
I have absolute faith in my team.
If they decided to enter the anomaly, they did so for a good reason.
No.
They've had their chance.
Get in touch with the Admiralty and HMS Frost.
- Move the Vanguard into position. - Vanguard?
- Isn't that a nuclear submarine? - What are you doing?
That anomaly is slap bang in the middle of
one of the busiest submarine vectors on the planet.
The Russians, the Americans, the Chinese all sneak around
playing hide-and-seek in those waters.
Can you imagine what would happen if one of their nuclear subs
disappeared off the coast of Britain?
It could start World War Three.
Don't worry, it will take him hours to get the Vanguard into position.
What do you think he's got in that briefcase?
Not his sandwiches, that's for sure.
We just have to hope the team reappear
before the Admiral opens his Pandora's box.
Sam, I've found the first box.
Three of the fuses are fried
and the trip switch has popped, but I can... I can fix this.
Has Officer Shaw found our missing crewman yet?
Officer Shaw, please respond.
Officer Neal?
I'll hold her steady and you free the cable.
Okay.
Will?
That wasn't me.
Sam, was that Shaw?
I think so.
It came from the comms in the storage room,
where that creature was.
What was that?
I can't say.
Okay. Sam, where's the Armoury? We might need weapons.
Only Nealand the Captain have access, I'm just the Midshipman!
Okay. Seal yourself in the con.
Whatever happens, you get Abby and Matt back on board, okay?
Just one more piece to go.
- Get ready to pull out. - Okay.
What the...
Come on, come on.
Okay, got it.
Pliosaur.
Pliosaurs.
They're checking us out to see if we're food.
- Okay, cut the power. - What?
Cut the power, we're going to play dead.
Get ready.
- Full reverse thrust, okay? - Okay.
Go!
Thank you.
HMS Frost will be on station in 10 minutes to resolve this.
Ten minutes?
You've had it on stand-by all along.
I had a hunch that your people couldn't pull this off,
not under water, and I was right.
- Initiate firing control procedures. - Yes, sir.
Anomalies are my jurisdiction.
National security is mine.
This operation is now under Naval command.
Nuking an anomaly won't work!
Nuking anything works.
Look, all you need to seal this anomaly is to pass an EM pulse through it.
My armament will do that.
And have you considered the implications to the Earth's time-line
of detonating a nuclear device in a prehistoric era?
We could cease to exist, or be turned into pond life.
The Admiralty deem it an acceptable risk.
Have we alerted Washington, Moscow,
- Shanghai? - Yes, sir.
- You told them about the anomalies? - No, we've told them there's been
an accident aboard one of our nuclear submarines
and asked them to remove all their personnel from the area.
Young lady, I need secure comms to HMS Frost.
Those pliosaurs are not going to ignore us for long.
Hey.
- Any sign of Mr Shaw? - No.
Right, we have to assume the creature's got him.
How do I talk to Connor?
Connor, the propeller's good to go.
There's a pod of pliosaurs out there waiting to get at us.
How are you getting on with those fuse boxes?
One more left to find.
Okay, watch your back.
Abby and me are going to go after the theropod.
Abby, you're going to take the lower deck.
Okay.
- Take this. Here. - Are you serious?
- Yeah. - Thanks.
- What about you? - I'll improvise.
Okay.
- Let us out. - Good luck.
- Can you show me the way? - Come on.
Well, this is great, innit?
Creatures outside where we can't see 'em,
creature inside where we've got no lights and no exit.
Got to be honest, I prefer hunting dinosaurs on dry land,
at least you can see them coming.
Connor, have you found that final box yet?
Well, I'm definitely in the right place.
But it looks like someone's relocated the junction box
without updating the schematic, which is...useful.
Well, hurry up, without power we can't get back through the anomaly.
Really?
Oh, because there was I thinking we could just all
stick our arms out of the portholes
and paddle our way back to the 21st century.
Okay, I'm sorry, just find it, okay?
I'm finding it, I'm finding it.
We're taking on water!
Connor, the attacks are just going to get more and more sustained,
you need to find that fuse box and fix it now!
HMS Frost from Admiral Marston,
you are authorised to deploy nuclear weapons
on target Vector 651 Delta.
Initiate firing code procedures.
James Lester, I'd like to speak to the Minister, please.
It's urgent.
What's it regarding?
It's regarding the end of the world as we know it,
happening in about 10 minutes.
So, if he could kindly step away from the cheese and crackers,
I'd really appreciate it.
"Alpha Zulu 4-2-5
"Echo Romeo 7-8-9 X-Ray."
Acknowledge.
Oh! Connor!
Yeah, friendly Connor. Harmless Connor.
Get the spanner out of me face Connor.
- You all right? - Yeah.
Oh!
- Have you found the final fuse box? - No. Not yet,
but there's only one last compartment where all the critical wiring runs to
and that's down there.
Go on, then.
Thanks very much.
I see. I see.
Yes, Minister. Of course.
Well, have a good apocalypse.
You're already pond life, you won't notice the difference!
Five minutes till they fire.
This part of the sub must have taken the brunt of the attack.
Okay.
There it is.
- I can do this, get on the bunk. - What?
On the bunk, out of the water.
Small and thin, right?
Think small and thin.
Good work.
All right, Matt, we've found the final fuse box
and captured the theropod.
She's alive.
- Comms back on? - Yes.
Good.
The hull won't take much more of this.
How long till we've got enough power to restart the engine?
Not long. At this rate, we'll never make it through in one piece.
We're going to have to distract the pliosaurs.
You said you could flood or vent any compartment at any time,
including the torpedo room, right?
In an emergency, yes.
Well, I think this is an emergency.
Abby, Connor, take the creature to the torpedo room, I'll see you there.
T minus 4 minutes.
This is a disproportionate response, Admiral.
My people will be dealing with the problem.
Your people are long ago and far away. We have no choice.
You're killing four of your team, three of mine,
irradiating God knows what era.
I am sorry, Mr Lester, but this is a matter of global security.
Someone has to take these decisions.
Regretfully, that's me.
- This way. - Okay.
No way is she going to fit in there.
She'll have plenty of help.
The room fills up with water, the pressure sucks her out.
Oh.
Okay, let's go.
There's too much damage to get more than 30% power,
but the propeller's working again.
T minus one minute.
Ever considered a sports car?
You know, that whole extension of masculinity thing?
I've got Dr Strangelove on Blu-Ray if that helps?
We need to get out of here. Sam, I need you in fire control alley.
Abby, Connor, you're going to steer the ship, come on.
Come on, now.
- Sam, what do we do? - Full astern.
English please, not everybody speaks Navy.
Backwards.
Think of it as if you're playing a video game, right?
Abby, that is us right there. That area is the anomaly,
you've got to guide us right through the middle, okay?
Okay.
Sam, we're going to go through the anomaly backwards
and then you're going to take the war shot, okay?
Understood.
- Distance to anomaly? - 500 metres.
Hold steady.
Let's feed these fishes, yeah?
Be my guest.
Hold it steady, it'll be okay.
It's working. They're taking the bait.
- Come on! - Ah!
It's good work, everybody. Maintain present course and speed. Nearly there.
Okay.
Torpedo away.
They're back! And the nuke is heading straight for them.
Disarm that torpedo.
HMS Frost, this is the ARC, I have an Admiral Marston for you.
Abort! Abort now!
Congratulations Admiral, you just fired a nuclear weapon
in peacetime at one of your own submarines.
Depth, 160 feet. We did it.
Okay, Sam, stand by with Connor's torpedo.
We're going to seal this anomaly.
What's that?
Incoming torpedo!
Plane down, 10 degrees, hard port.
Why would someone be taking a shot at us?
Down left, dive, dive!
It's going to hit them!
Whoa, whoa, whoa, what happened then?
They got out of the way.
Yeah, but the nuke is still heading towards the anomaly.
It's heading straight for the anomaly, what should I do?
We're going to stick with the plan. Let's lock this anomaly.
You two, straight forward. You ready?
- Fire. - Torpedo away!
- There's a second torpedo. - It's Connor's.
He's trying to close the anomaly.
HMS Frost, I need confirmation of that abort order!
- Impact! - Okay.
Good shooting, Captain!
I bet you're glad I made you play all those video games now.
Yeah.
They did it. The anomaly's locked.
Well? Was the nuke disarmed in time?
They, uh, they think so.
Oh. Well, that's reassuring, isn't it?
If not, I think we know what caused the mass extinction of the dinosaurs.
Hello? Speaking.
Yes, of course. One moment.
- Admiral? - Yes?
- It's for you. - For me?
It's the Prime Minister.
Yes, Prime Minister?
I can explain everything.
Well, it's good to breathe fresh air again.
Yeah. I've just got to...
Philip? Hi. Yeah, no, we're back, safe and sound.
Listen, I've got an idea.
What's up?
Philip.
Connor called him as soon as we were back on dry land.
On the sub, working together,
for a moment there it was like it used to be.
Yeah, no, it should be fine. Yeah, I...
Before the secrets.
Hey. Come on.
Yeah. Obviously, I'm at work now, I can't really say too much now,
but I think you're going to be excited.
I know. Yes, thank you.
Uh-huh. Yeah. Yeah, cool. Got to go.
Coming home?
Listen, Abby, I really want to get this finished, so...
What's up?
You know how much I believe in you.
And I'm really happy you're enjoying your new work.
But?
But...
there's something not right about Philip.
I don't trust him, Connor.
- Abby, we've... - You trust my instincts,
you always have, and right now
my gut is telling me you need to pull away from this.
Listen.
I...I understand the reasons why you feel the way you do about Philip.
I totally get it, the menagerie thing, that's...
It's not about the creatures.
You've just got to trust me on this.
How about you trust me?
Philip's a good man
and what we're working on, it's important
and if it all works out the way we want it to, it's...
It's going to be so important.
Uh-huh.
I'll see you at home.
Abby, I promise you, when this is all finished,
you'll be proud of me.
I was already proud of you.
Matt.
- You okay? - Yeah.
Look, I know your mission is more important than any of us,
but it's not the only thing that matters.
What's this?
You want to know what happened to Emily.
I know you do.
