Swimming Pool. Anthony Barton, a male lifeguard dives into the pool; he and Diane Johnson, his girlfriend and co-worker, are using the pool after hours. The Diane gets out of the pool and goes to get changed. She dries her hair as Anthony goes to dive into the pool again. A Mosasaur swims below him and leaps up as he dives in. Anthony screams as he is swallowed whole. Diane hears and goes to investigate.

Diane: Anthony?

She walks back toward the changing rooms, past a window that looks under the surface of the pool; the mosasaur rams the window, making her scream.

Nick Cutter, Claudia Brown and James Lester are in a conference room with several other officials, watching and listening to Connor Temple reporting on the status of the anomaly from the last episode via some sort of video link.

Connor: The magnetic field is remaining consistent at five tesla. At this point there is no sign of deterioration. Let me demonstrate. Huh?

On-screen, Connor holds up a metal flask.

Lester: Who's that idiot?

Nick: Connor Temple. He looks like a half-wit, but he has a very good brain.

Connor lets go of the flask, and it flies into the anomaly.

Connor: Woah! Bulls-eye! That kills me every time.

Lester: We may stand on the brink of Armageddon, but at least we have an irritating student on our side. How reassuring.

Connor: Is this thing still on?

The video link is switched off.

Lester: The previous anomaly proved to be temporary. As you've just heard, this one shows no sign of weakening.

Nick: The anomalies may be intermittent, and they fade from time to time, but they never completely disappear.

Lester: Well, if that were true, creatures would have come through before.

Nick: Maybe they have. Ancient civilisations have spoken of monsters and dragons. Perhaps they weren't as naïve as we assumed. The anomalies are conclusive proof that the past exists in a fourth dimension as real and solid as those we already know. Our job is to predict and contain them. We need to establish what…

Lester: Thank you, Professor. We'll take his from here. The Professor is speaking in an independent capacity. Official policy is yet to be finalised.

A man walks in and hands Lester a note.

Lester: It appears we may have another one.

Hospital. Stephen Hart is packing up the things he had with him in the hospital due to the events of last weeks episode. Connor is with him.

Connor: You really can't remember a thing?

Stephen: Not a thing after I went into the tunnels. Probably for the best though, right? Still, they say it's only short term, so, you know…

Connor: It's all been pretty scary, hasn't it? You know, it's not until you got bitten that I though that one of us might actually die from doing this. Really upset me.

Stephen: You must have gone through hell.

Connor: Yep.

They both grin.

Connor: It did make me think about what's important though, you know. Sorts out your priorities a bit. If you get killed, can I have your iPod?

Abby Maitland walks in before Stephen can reply. She is wearing a skirt. The guys do a double take.

Connor: Is that perfume?

Abby: I can do the girl thing, you know.

Connor: Ooh.

Stephen: You look really good.

Abby: Thanks.

Stephen: It's good of you both to come. Shouldn't have bothered.

Connor: Don't flatter yourself. Some of us just like hanging out with nurses.

Abby: Come on, I'll give you a life home.

Stephen: Oh, there's no need. Hilarie's picking me up.

Abby: Oh

Stephen: Bye

Connor waves as Stephen leaves.

Connor: If you carry on, Hilarie is going to beat your ass.

Abby throws a pillow at Connor.

Abby: Sorry.

Connor: It's alright.

Abby: Well, so much for the girl thing.

Connor: I think you look great.


Swimming Pool. Nick and Claudia are talking to a Police Inspector as the walk along the side of the pool.

Inspector: Pretty obvious she killed her boyfriend, but we don't know what she did with the body. Just keeps babbling on about monsters and sea serpents.

Nick: Would you let me talk to her?

Inspector: What about? Monsters? I'm conducting a serious murder investigation here…

Nick: There was no murder. Anthony Barton was killed by an ancient marine predator, which then returned to its home, millions of years in the past.

The Inspector turns to Claudia as Nick walks away.

Inspector: Who are you people?

Claudia: I'm sorry. Thanks for you're time Inspector. Cutter, wait.

Nick: The girl's innocent.

Claudia: I know.

Nick: We can't let her go to jail for something she didn't do.

Claudia: Leave that with me, I'll do what I can for her.


Swimming Pool. Connor and Abby are sitting at the edge of the pool, Connor has taken off his shoes and socks and is dipping his feet in the water. Stephen, who is wet and is wearing the bottom part of a wet suit, joins them. He sits down and puts on flippers. Hilarie enters, just arriving.

Connor: With all this chlorine in the pool, I'm surprised the creature came through. To a reptile it would have been like swimming in a bucket of acid.

Stephen: Yeah. It probably sensed the danger and got out fast before the anomaly closed.

Abby gets up and walks away carrying a sample case. Stephen has his flippers on now, and he cleans the lenses of his goggles before putting them on.

Connor: Hey Hils.

Hilarie: Hils?

Connor: Yeah, its my new nickname for you.

Hilarie: Ok.

Stephen: Where've you been?

Hilarie: Somewhere.

Hilarie leans down and kisses him before walking away to join Abby.

Connor: Do you think she's hiding something?

Stephen: Yes.

Stephen dives into the pool.


Home Office. Claudia and Lester are walking through the building.

Claudia: The police have charged Diane Johnson.

Lester: I know.

Claudia: We have to intervene.

Lester: We're not going to do that.

Claudia: Why not?

Lester: Because I won't allow this story to become public property. At least in prison the newspapers can't get hold of her.

Claudia: So you're just going to let them lock up an innocent and traumatised girl?

Lester: Of course it's undesirable, but it would be far worse to release her to cause panic and disorder. I'll see that the charges are dropped when the immediate crisis is under control.

Claudia: That could take months.

Lester: And would you rather tell the police that an ancient sea monster is cruising our swimming pools consuming lifeguards? I know the injustice stings, but the correct decision is often painful. That's the burden of government.

Reservoir. The small harbour has a pier and a few boats moored up. Lots of people are around, walking along the waterfront, sailing, canoeing, visiting a café etc.

The mosasaur swims through the murky waters of the reservoir.

A large lump of meat floats to the surface in front of a set of canoeists. A woman screams and people start to run around.


Home Office. Lester is sitting at his desk. Claudia and Nick are standing in front of him. Claudia has a set of photos. She gives them to Lester.

Claudia: Well, the DNA is conclusive. It's the boy from the swimming pool. Or what's left of him.

Nick: It's a bolus. A regurgitated mass of flesh and bone. The beast swallowed him whole and then vomited up what it couldn't digest.

Lester: And what kind of creature could have done this to him?

Nick: What you should be asking yourself, is how the remains of a boy who was attacked in a swimming pool, end up 20 miles away in a reservoir.

Lester: Maybe there never was an anomaly. Maybe the girl murdered her boyfriend in the swimming pool and dumped his body in the reservoir.

Nick: It's very likely, provided you also believe she swallowed him whole and then drove 20 miles down the motorway to regurgitate his remains.

Lester: All right, then you explain it.

Nick: We know it was the same beast in the pool and the reservoir. Perhaps the anomaly has a fixed point of origin in the past, yet somehow it remains fluid in our time. They don't just open, they move.

Reservoir. Nick and some soldiers arrive at the pier. Claudia and CAPTAIN RYAN and his men are already there, along with Connor (who is marking water levels) and Abby, Hilarie and Stephen (who are testing water samples).

Nick: How are you?

Ryan: All right.

Claudia: We haven't found anything yet. No creature, no anomaly, no nothing. We're still searching the reservoir, but with any luck the anomaly's closed again.

Nick: I need detailed local maps, lists of swimming pools, rivers, lakes, anything nearby. Can you get those for me?

Claudia: Should I be asking why?

Nick: It's just an idea.

Claudia: Do you know what I miss? Those soul-crushingly dull civil service meetings, which made suicide look like an exciting career option. I used to sit there praying something would happen in my life

Nick: Careful what you wish for.

Connor: Professor! Professor!

Nick rushes around to the other side of the pier to where Connor is poking a stick into the water. The stick has a piece of red tape around it part way up. The water doesn't reach it.

Connor: You're really going to want to see this. The reservoir's land locked, right?

Nick: Yes.

Connor: So, allowing for condensation and rainfall, the depth should be pretty consistent.

Nick: Yes.

Connor: Well, I made this mark at water level earlier

Connor shows Nick the tape, then puts the stick back in the water.

Connor: The water level's fallen 40 centimetres since then.

Stephen runs up to them.

Connor: This isn't a reservoir any more, it's a tidal lake. The water's literally pouring out of it.

Nick: It must be flowing out through the anomaly.

The three men turn and stare out across the reservoir.

Nick: Which means it's still down there somewhere.

The mosasaur is still swimming around down there.

Nick is standing staring over the water. Claudia joins him and hands him a hot beverage.

Claudia: Here you are.

Nick: Thanks very much.

Claudia: Thinking about Helen?

Nick: How did you know that?

Claudia: Highly trained civil servant. We're famous for our emotional empathy.

Nick: Whatever I'm doing, she's always there. She never really goes away.

Claudia: Strange. Of all the people in the world to hallucinate, Stephen chose Helen.

Nick just stares across the water.

Nick: Steam. Don't you see? The tide must be coming in, bringing in warmer water from the other side. The steam is telling us exactly where the anomaly is.

Reservoir. Soldiers are running around making preparations. Nick and Stephen are in wet suits along with a couple of other guys; they get into inflatable boats to go out further into the reservoir.

Claudia: I suppose there's no point in asking you not to go down with them.

Nick: You don't have to worry about me.

Claudia: I'm not. I'm just thinking about all the paperwork I'll have to do if you drown. No idea how many forms I'll have to fill in. What if you're right and the creature's still down there?

Nick: We'll find it. All right?

Nick and Stephen leave in the boat as Claudia and Ryan watch from the pier.

Connor, Hilarie and Abby watch Nick and Stephen leave, and then walk along a small beach by the pier. Abby is carrying a sample case.

Connor: Why does Stephen get all the fun stuff to do whilst we get stuck collecting water samples?

Hilarie: Because he's got some idea what he's doing.

Connor: That's debateable. I could do the action stuff too as well, you know. I'm not just a massive intellect.

Nick and Stephen don scuba tanks and masks and dive into the water along with a couple of soldiers.

Connor: He doesn't remember a thing, you know, Stephen.

Hilarie: Yeah, i know. And it's bloody annoying.

Abby: To be fair he was just poisoned by a prehistoric centipede.

Nick and Stephen are under water, doing various checks. Nick gives the 'OK' sign.

Hilarie: Its just one of the most important things i tell him, he goes and forgets it.

Connor: What was it?

Hilarie just looks at him not answering him. There is also a mosasaur, which is still swimming around down in the reservoir. Nick and Stephen are also down there.

Connor, Hilarie and Abby are waist deep in the reservoir, collecting samples of the water. They are a little way away from each other, when something spooks a pair of swans nearby and they take off. Connor watches them suspiciously. He sees something else.

Connor: Abby? Hilarie? Um, what's that?

The mosasaur surfaces nearby and swims towards them.

Nick and Stephen are still underwater. Suddenly, the soldier who was swimming in front of them disappears through the anomaly. They stop and stare.

The mosasaur starts to circle Abby, before going back under again.

The mosasaur is deep underwater. Nick and Stephen are at a similar depth, they swim to the surface and get back into the boat.

Connor, Hilarie and Abby are in the same positions. Connor shifts slightly.

Abby: Don't move!

A shot of the mosasaur.

Stephen and Nick are back underwater recording the anomaly.

The mosasaur cannot be seen near Connor, Hilarie and Abby.

Hilarie: Go!

They three of them move as quickly as they can through the waist deep water.

The mosasaur moves quicker.

Connor: Quickly Abby! Hilarie!

They reach the edge of the water and scramble up a small bank before turning back to the water.

Connor: Jump! You two okay?

The mosasaur leaps out of the water and tries to reach them, but it can't climb up the bank. Connor, Hilarie and Abby move from side to side, trying to keep out of its reach, staying pressed against the fence. Hilarie gets out of the way. Connor pushes Abby out of the way.

Connor: Move now! No back!

He darts forwards and grabs an oar from one of the canoes left on the bank. He lunges forwards, trying to hit the mosasaur with it.

Abby: Connor, be careful!

Connor hits the mosasaur over the nose a couple of times before the oar breaks and somehow gets lodged in the roof of the mosasaur's mouth. The creature shakes the oar loose and turns away, diving back into the water.

The mosasaur swims towards Nick, the only diver with the anomaly, shaking it's head and roaring. It leaves a slight trail of blood behind. It swims past Nick, ignoring him completely, and enters the anomaly. The anomaly closes soon after.

Reservoir. Connor is talking to Nick about what happened.

Connor: Some kind of mosasaur, maybe six or seven metres. Cretaceous, at a guess.

Abby and Hilarie are being checked out by Ryan's medics, they are wrapped in a blanket.

Nick: Scary. And at that size, it couldn't have been fully-grown.

Medic (to Abby): Take deep breaths.

Connor: Yeah.

Nick: Which is just as well for you.

Nick pats Connor on the back and rubs his shoulder as Claudia approaches. They turn to face a group of Ryan's men who are standing a short distance away with Ryan and Stephen.

Claudia: They're all really upset about losing the diver. Tell me exactly what happened.

Claudia and Nick walk towards the group, leaving Abby, Hilarie and Connor behind.

Nick: He swam through right in front of me. He should have been able to make it back through.

Claudia: Something must have stopped him. Are you absolutely certain the anomaly's closed?

Nick: Straight after the mosasaur went back through. The water temperature's already returned to normal.

Claudia: Then we've lost him.

Nick: Yeah.

Abby approaches Connor and grabs his hand.

Abby: You saved my life.

Connor: I did, didn't I?

They hug.

Abby: Okay.

Connor: What?

Abby: You can let go now.

Connor: Oh, yeah, I'm sorry. I just…

Abby: Thanks.

Hilarie: Yeah, thank you.

Home Office. Lester, Hilarie, Claudia, Nick and Stephen are in a meeting room, there are a load of maps on the table.

Nick: The anomalies are times equivalent of an earthquake. Strong enough to rip apart the boundaries between dimensions. My guess is that the fault line ruptured at the swimming pool, then ran to the reservoir. It could crash its way through into our time again anywhere along this line.

Lester: Earthquakes? Temporal fault lines? Are we trying a little too hard people? It's random chance, that's all. There's no connection with any of it. Try to look on the bright side, Cutter. The anomaly's gone, the crisis is over and I'd say we got off pretty lightly.

Claudia: Except that a good man in now permanently marooned in the past.

Nick: There could be another breach along the fault line at any given moment. You should be stationing troops at every significant body of water between the reservoir and the coast.

Lester: The press would be crawling all over us in seconds. How on Earth would we explain it? I mean, you admit that it's all conjecture?

Nick: Yes, of course it is, but I'm right.

Lester: You people, you're worse than the climate change mob. One cold day in July and suddenly it's the new Ice Age.

Nick: You're making a mistake. If and when the anomaly breaks through again, I guarantee you it will be somewhere along this line.

Family Home. Two children are running outside to play; their mother is following them.

Woman: Okay, guys. Ten minutes before school.

She takes a basket of dirty washing down into a cellar picking up dirty clothes along the way. She loads the washing into a washing machine and switches it on. Water is covering the floor from the other side of the room, she doesn't notice. The woman goes back up stairs and picks up her kids' school bags. She turns and notices the wet footprints she has left. She goes back into the cellar and finds the floor covered in water. She runs back upstairs as a plug socket sparks. We see a glimpse of a Hespernois.

Central Metropolitan University. Connor is in the cafeteria, working on his laptop. His friends Tom and Duncan approach him. Duncan sits opposite him whilst Tom remains standing.

Tom: Mosasaur, eh? Cretaceous era marine predator. Anything from 2 to 20 meters in length and two tonnes in weight. Extinct 65 million years ago.

Connor closes his laptop and gathers his stuff together.

Tom: I was reading that. What's this? New project?

Connor: No. No. No, no, no, just interested. Oh, is that the time? I'm going to have to go.

Tom: Whoa, what's the rush? It's DVD night. 'Battlefield Earth', director's commentaries. Your turn to get the pizza.

Connor: Right. You know what? You can have it on me. I've really got to be somewhere.

Connor hands Duncan some money and then leaves. Tom sits in the seat he just vacated.

Tom: What's got into him?

Duncan: Maybe he's still angry over our practical joke.

Tom: Come on. That fake dinosaur was a masterpiece.

Duncan: Yeah. Perhaps he's got a girlfriend.

They both laugh.

Duncan: Nah.

Tom: Well, it must be pretty radical. He missed my Gerry Anderson marathon last weekend as well. Said he wasn't interested.

Duncan: How weird is that?

Tom: Why the sudden obsession with dinosaurs?

Duncan: Maybe he's onto something. A dig somewhere, a good fossil, something he wants to keep to himself.

Tom: Which would be selfish. You know, I think we need to keep a closer eye on that boy.

Home Office. Stephen is walking through the building. He sees a screen with a bunch of pictures of the room where he was attacked in. He has a couple of flashbacks.

Stephen (thoughts): Helen.

He ends up leaning on a stair rail. Nick comes down the stairs and pats Stephen on the back as he passes, he is carrying a rolled up map.

Nick: Come on, let's go.

Nick stops when Stephen doesn't start to move.

Stephen: I've been remembering things.

Nick: You mean Helen?

Stephen: Why didn't you tell anyone? Did you go looking for her?

Nick: Look, if she wanted to talk to me then she could have. Why keep playing games with me?

Stephen: You mean this isn't the first time? How long have you known she was alive?

Nick: Look, not long. But all these years, she let me think she was dead. She let me go through that. What does that tell you?

Stephen: Come on, there could be all kinds of reasons why she stayed away. The point is she wants to see you now.

Nick: She left you to die on your own.

Stephen: Maybe she thought help was coming.

Nick: Maybe she didn't care. You think I don't want to know what happened? I've thought of nothing else for eight years. But what if…What if the truth is worse than not knowing? Are you going to tell the others?

Stephen: No, it's not my call. But if she was my wife, I'd go through a million anomalies for her.

Nick: Yeah, but she isn't, is she?

Stephen: But she was important to me too.

Nick: I know that.

Nick turns to leave.

Nick: Are you coming?


Family Home. The woman is showing a plumber down the stairs into the cellar.

Plumber: Uh, I thought you said you got a leak in the washing machine, love. Not an indoor pool.

Woman: Can you stop it?

Plumber: We'll see.

The plumber wades into the water; it's up to his waist. The woman stays on the stairs. He checks behind the washing machine.

Plumber: Well your connections are fine. It must be a mains leak.

There's a splashing sound behind him and he turns around, shining his torch into a dark area of the cellar.

Plumber: Well, your dog's enjoying a swim anyway.

Woman: We haven't got a dog.

She goes back up the stairs and the plumber takes a look around. A hesperonis is perched on a counter top. It lunges at the plumber as he goes past. The plumber stumbles backwards and falls over; he flounders in the water as the creature keeps attacking.

Plumber: Help me!

The hesperonis dives into the water and starts biting at the plumber.

Plumber: Help me!

He manages to get his feet under him and stumbles to the stairs as the woman comes down.

Woman: Are you all right?

He starts to go up the stairs but is dragged back under. The woman screams.


Home Office. Claudia and Lester are discussing what happened at the house.

Claudia: We haven't clarified the exact picture yet, but it looks like a plumber was attacked in some woman's cellar.

Lester: I'm surprised, have you seen how much these people charge?

Claudia: She claims that the damage was done by some kind of large reptile.

Lester: And I suppose you're going to tell me this town lies directly on Cutter's mythical fault line? I'm really beginning to dislike that man.

Family Home. A body floats to the surface of the pool in the cellar. It is the diver they lost at the reservoir.

A bunch of black jeeps pull up outside the house, Ryan and his men are inside. Ryan is in his civvies, as are his men.

Man on radio: All units, a second body has been found in the basement. I repeat, a second body has been found in the basement.

Ryan on radio: Zero to team Bravo. Move into position and set up…

Ryan and two others enter the house. The divers body is being zipped into a body bag. There is a handkerchief tied around his wrist with the initials H.C. on it.

Ryan: Hold on.

Ryan takes the handkerchief and makes a call.


Home Office. Lester and Claudia are in a meeting room.

Lester: I want the press kept as far away from this as possible. If we have to, we go with an escaped crocodile story, but apart from that, we deny everything.

Lester starts to leave, when Claudia's phone rings.

Claudia: Sir. Claudia speaking. Right. Thank you. Bye-bye. They found a body in the basement. Special forces diver.

Lester: Great.


Family Home.

Claudia arrives in a jeep. Ryan moves to greet her.

Ryan: It's our diver. The man we lost in the reservoir. Looks like he died of shock. They found this tied around his wrist. We don't know how the hell it got there.

Ryan shows Claudia the handkerchief. She notices the initials.

Nick, Hilarie and Stephen are in the cellar watching some soldiers poke around. Claudia joins them on the stairs.

Nick: What kept you?

She gives him a look.

Nick: What is it?

She shows him the handkerchief.

Hilarie looks straight to Nick at seeing the handkerchief, confused. Nick and Claudia are upstairs by the door leading to the garden. Nick is leaning on a windowsill and Claudia is standing in front of him.

Nick: Helen's mad old aunt used to give us those handkerchiefs, um… Same present every single birthday and Christmas, and we used to make jokes about them. That's a message. It means Helen's waiting for me on the other side of the anomaly.

Claudia: Just like she was in the Underground.

Nick: Yeah.

Claudia: Why didn't you tell me? You lied to me, to all of us.

Nick: Try and see it from my perspective. I had just found out that my dead wife was still alive.

Claudia: She might know things. Things that could help us. You have no right to decide what we should know and when we should know it.

Nick: She's my wife.

Claudia: Maybe in your mind that gives you some kind of special privilege, but this affects all of us. If you can't see that, then you just can't be here anymore.

Claudia throws the handkerchief to the floor and walks away.

Outside, Abby has arrived and is helping Hilarie unload gear from the back of a jeep. Stephen is watching Hilarie, before hugging her from behind. Hilarie laughs, as he kisses the side of her head.

Stephen: My memory's back. Some of it anyhow. Enough to know why you're here and there.

Hilarie: And? We've got a job to do.

Stephen: Can we at least talk about it?

Hilarie: Sure.

Stephen: Are you seriously thinking about carrying on with this job when your pregnant?

Hilarie: I'm not thinking about it. I'm doing it.

Stephen: Ok, Ok. I just want to tell you that i think it's brilliant.

Hilarie: Good.

Stephen: I love you.

Hilarie: Love you too.

Lester arrives in a posh car, with a police escort. Ryan greets him as he exits the car.

Ryan: Area secure sir.

Lester goes into the house.

Family Home. Lester, Ryan and Claudia are standing in front of Nick, Stephen, Hilarie, Connor and Abby. Lester is not happy.

Lester: The revelation that Helen Cutter's still alive changes everything.

Connor: She's still alive? Um, how did I miss that?

Hilarie: Long story.

Connor: So, eight years, she's been living in the past. My God. How are we going to explain Celebrity Love Island to her?

Claudia: Shut up Connor.

Lester: She's eight years ahead of us in terms of understanding the anomalies. Her knowledge could be priceless and we have to share it.

Stephen: Which is fine if she was here, but she isn't.

Lester: Which is why we're going to go and find her. We know she wants to make contact. She must be brought back here, by force if necessary.

Nick: This is my wife you're talking about.

Lester: Which is why I want you to go through the anomaly and bring her back. You will of course have a military escort.

Nick: To do what? Shoot her if she won't come back?

Lester: To protect you, both of you. The alternative is you sever all ties with the anomaly project with immediate effect, and we'll go and find her ourselves.

Nick: Okay, on one condition. I go on my own. There's no question of force. I'll do my best, but if she doesn't want to come back, then that's it.

Claudia: How can we trust you?

Lester: Oh, I'm sure Professor Cutter won't let us down again. You will try and remember what side you're on, won't you?

Nick is all geared up for the dive and is making the final preparations. Stephen is with him, crouching on a wooden platform in the cellar.

Stephen: Okay, so you've got about an hour of air, and a mile of rope. Take a compass reference as soon as you get there, and just stay attached. After two hours, we'll reel you back in. The water pressure in the anomaly is going to be intense, okay? So the harder you swim, the more air you're going to use.

Stephen holds up a harpoon gun.

Stephen: Now this has an effective range of about ten metres. If you have to use it against a predator, wait until you see the whites of its teeth.

Lester and Claudia are having a discussion/argument outside the house.

Stephen, Claudia, Ryan and another soldier are on the platform, watching as Nick dives. Stephen starts playing out the rope. Hilarie comes and joins him. Nick swims through the anomaly and emerges on the other side. Lots of hesperonis' are swimming around him, but none attack him.

The Past. Nick surfaces and goes to the shore. He leaves his scuba gear (and the rope it's attached to) on the beach, along with the harpoon gun. He take a look around, some flying creatures are above the other side of the lake.

Nick: Helen!

Nick sets off along the beach and climbs a rock formation. Hesperonis are perched on the rocks and hiss at him, but don't attack. He gets half way up the cliff, when he hears a splash. He looks to his left and sees HELEN CUTTER swimming, naked, in a small pool below.

Helen: Hello Nick, I see you got my message.

Helen is getting dressed; Nick has his back to her whilst she does so.

Helen: You've lost weight. You haven't been eating properly.

Nick: You let me think you were dead.

Helen: I am dead as the person you knew. My old life ended eight years ago. You know, you can turn around, I'm decent. There's no easy way to do this, is there?

Nick: Well, maybe we should just skip the small talk. Why didn't you come back?

Helen: What are you really upset about Nick? That I stayed away, or that I didn't tell you what I was doing?

Nick: I'm not upset Helen. I just don't know who you are anymore.

Helen: you want to know why I didn't come back? Because I knew your conscience would make you throw all this out there for everyone to trample over and I wasn't ready to share it then. Hey!

A hesperonis gets too close and Helen throws a rock at it.

Helen: Hesperonis. Scary up close, but cumbersome and very stupid. What do you want Nick? An apology? What's the point?

Nick: Eight years of my life back would be nice.

Helen: Look, come on. People grieve and then they heal. It happens all the time. Why should you be any different?

Nick: Well, why come back at all then? Let me guess, you want something.

Family Home.

Stephen and Hilarie leave the cellar and joining Connor and Abby on the ground floor. Abby has a stopwatch and Connor is looking at some maps.

Stephen: Abby, how long has he been?

Abby: 91 minutes, 41 seconds.

Connor: The drains. Stephen? In theory, a creature could make its way along the sewage system all the way to the river, and once it's there, it could go anywhere.

Stephen: And?

Connor: Well, good news is the size of the drains rules out anything bigger than a small mosasaur.

Abby: Well, how small.

Connor: Not small enough.

Hilarie: And i thought today couldn't get any better.

Claudia enters the rooms with a bunch of guys who are pulling on wetsuits.

Stephen: What's going on?

Claudia closes the door on them.

Hilarie: I don't like her.


The Past. Helen hands Nick the lid of a thermos flask and fills it for him.

Nick: You've come back before? Did you watch me grieve? Did you come to the funeral?

Helen: No. Was it good?

Nick: It was okay.

Helen: I'll answer all your questions, Nick. All you have to do is come with me. There are more anomalies than you can possibly imagine. I know how to find them.

Nick: I asked you a question. Why do you want me now? After so long?

Helen: I'm human. I want company. I want to share this incredible gift, but only with you. Nick, I have seen such wonders. Things you wouldn't believe.

Nick: You're asking me to abandon my life. Leave behind everything I know. You know, people are dying back home, and you want me to just run away with you?

Helen: Animals die, Nick. Species die. You know I'm right. One day, humanity will disappear, just like the dinosaurs, and nature doesn't care, something else will just take our place. Nick, just leave all the other stuff behind. Come with me.

Nick: I've got a job to do, you could help me if you like.

Helen: You're rejecting me?

Nick: I'm asking you to come back with me.

Helen: I offer you the key to time. The key to time, Nick. And you turn your back on it? Call yourself a scientist?

Nick: I call myself a human being.

Nick walks away and Helen watches him go. Nick dives back into the lake, and Helen watches him go. Nick has almost reached the anomaly when a mosasaur approaches. Nick watches as it swims above him. He turns back around and starts as he sees another mosasaur, smaller than the first, heading towards him. Nick swims away, but the mosasaur head butts him. The mosasaur circles around and Nick fires the harpoon at it. The weapon grazes the creature, making it mad. Nick continues to swim towards the anomaly, but the mosasaur comes up behind him and manages to slice through Nick's air hose. He slides the scuba gear off, leaving just the rope tied around him. The shadow of the larger mosasaur appears behind the smaller one. Just as the small mosasaur is about to attack Nick again, the large one attacks it front the side, killing it and swimming away with it.

Family Home. Abby and Connor are on the ground floor. Connor is still looking at maps and Abby is pacing. She sighs.

Abby: His times up.

Stephen, Ryan, Hilarie and another solider are in the cellar. Abby's voice comes over the radio.

Abby on radio: Stephen, that's two hours. He'll be running out of air.

They start pulling Nick through the water. Claudia joins him.

Stephen: Come on, come on. He's lost his tank.

Claudia: Quick, get him out.

Nick is unconscious, Stephen and Ryan jump into the water to drag him out.

Hilarie: Nick!

Ryan: Get his head up.

Stephen: He's not breathing.

Stephen and Ryan lift Nick onto the platform with Hilarie's help. Hilarie starts to give Nick CPR.

Ryan: Medic! Get some air inside him.

Nick starts coughing up water, and sort of wakes up a little. Stephen and Ryan support him on either side and take him up the stairs. A stretcher is brought to the top of the stairs and Nick is put on it.

Claudia: Was Helen with you?

Nick: Yes.

Claudia: So she was there. [To Ryan] You know what to do.

Ryan: Let's go.

Ryan goes back downstairs, followed by a bunch of guys in wetsuits and scuba gear.

Stephen: Who's this?

Claudia: Sorry, it's out of my hands.

Stephen: What?

Hilarie: What do you mean by that?

Claudia leaves the house, leaving Stephen and Hilarie standing in the hallway.


Family Home. Nick is sitting in an ambulance outside the house, Abby is inside with him and Connor is standing by the door. Both of them look worried and Connor keeps glancing back to the house. He watches one of the soldiers at the front of the house get a message on his radio.

Nick: How long have I been out for?

Abby: Not long.

Nick: I have to talk to Claudia.

Abby: There's something you should know.

Nick steps out of the ambulance, and three soldiers rush forwards, point their guns at him.

Soldier: Stand still. Don't move!

Nick: What's going on?

Soldier: Stay still.

Lester comes out of the house, followed by Ryan, and two of his men. Between them, they are holding Helen. Stephen and Hilarie are following them. Helen shoots an accusing glare at Nick. Nick looks shocked. Connor and Abby look slightly nervous about the guns being pointed at them, and a soldier is holding both Hilarie and Stephen back at the house. The soldiers put Helen in a car. Lester also gets in a car with Claudia. They drive away with their police escort.

Hilarie: I think i'm going to be sick.

The soldiers let her go just in time for her to be sick.
