[Attic]

SARAH JANE [OC]: But after all my adventures, the last thing I expected was a family. And that's been the most amazing adventure of all.
LUKE [on PC]: I've got to go soon. Saturday is band night at the Student Union.
CLYDE: What? You're going to watch a band? We are talking music here? Electric guitars, drums, not some physics experiment with elastic, right?
RANI: Clyde, don't be soft. Soon Luke will have seen more cool new bands than you've ever heard of.
LUKE [on PC]: Yeah, you'll be so after my tunes next time I'm home.
SARAH JANE: Oh Luke, I can't wait.
LUKE [on PC]: Look, I've got to go now, so I'll catch you later.
SARAH JANE: Love you.
(But he's already out of range of the webcam.)
CLYDE: Right, homework.
RANI: Yeah.

[Front door]

RANI: Luke will be back soon, clothes all over the place. Empty mugs, dirty places, lots of loud music.
SARAH JANE: You're tight. I should make the most of the peace and quiet. Night, night.
RANI: Night, Sarah Jane.
CLYDE: See you tomorrow.

[Sarah Jane's home]

(At 5.34 on Sunday, Sarah Jane is woken by an insistent ringing of her doorbell. She opens the front door.)
SARAH JANE: Hello?
(To discover a carry cot on her doorstep. Naturally, it contains a baby.)
SARAH JANE: What the?
(She runs to the road to see who left it, but there are no other people around. She carries the infant indoors.)
SARAH JANE: Oh, why would anyone leave you on a stranger's doorstep?
(The baby cries and all the light bulbs explode.)
SARAH JANE: Oh!

[Chandra home]

(Rani is woken by her text alert tone. 07:12 Help! Come quickly. SJ. Meanwhile, downstairs -)
GITA: All the bulbs in the house? Even the fridge? I'm telling you, Haresh, that's not normal.
HARESH: I'll get an electrician to check the wiring on Monday.
GITA: I hope we're not on a ley line. I saw this programme on the telly. They run all over the country connecting sites of ancient power, like Stonehenge and the White Horse.
HARESH: What, the pub on Bishton Street?
GITA: Very funny, aren't you. You should give up teaching and become an undertaker.
(Rani rushes in, looking for her jacket.)
GITA: Hey, where are you off to in such a hurry?
RANI: Sarah Jane's. Luke's texted me. He can't get an answer. Wants me to check up on her, you know. It's probably nothing. Bye.
HARESH: Phone's probably on the blink. It'll be the ley lines.
(Rani leaves.)
GITA: Here, how many comedy headmasters does it take to change a light bulb?

[Attic]

RANI: Sarah Jane, what's
SARAH JANE: Shush.
RANI: That baby doing in your arms?
SARAH JANE: Shush. Don't make her cry. She cried earlier, and every light in the house blew.
RANI: In the street, more like.
CLYDE: I got what you said in your message, but what do you want nappies for? (then he sees.) I sort of feel that should explain everything, but actually I'm even more confused.
SARAH JANE: I found her on the doorstep. I was going to call the police, but I don't think they'll have much luck finding her parents. Not on this planet.
(Baby cries, bulbs go bang.)
SARAH JANE: Shush, it's all right. it's all right. Luke was born a thirteen year old boy. A teenager I can handle. But a baby? An alien baby? I need help.
RANI: Don't look at me.
CLYDE: Or me, obviously.
SARAH JANE: Yeah, well, your mums must know.
RANI: If I start asking Mum questions about how to look after a baby, well, she's going to totally freak. Besides, she's an alien. What do any of us know?
CLYDE: What about Mister Smith?
SARAH JANE: Ah. Mister Smith won't come out. Well, would you if you might get your circuits fried?
RANI: You see, with most babies, all you have to worry about is poo and puke.
SARAH JANE: Yeah, well, this one doesn't blow bubbles, she blows things up.
(Whaa! Bang!)
CLYDE: I only know one way to shut up a baby.

[Lounge]

(So Clyde gets to feed baby her bottle of formula milk.)
CLYDE: See? Happy tummy, happy baby, whatever planet you're from. I've looked after my little cousin a few times, not that she's an alien.
RANI: You're a natural, Clyde.
CLYDE: Well, little kids are cute, aren't you, Sparky?
SARAH JANE: Do you think so? I always think babies look a bit rubbery.
RANI: Her mum and dad will be going out of their minds with worry. They must be scouring the galaxy.
SARAH JANE: Maybe. Maybe not. Whoever left her on my doorstep, that was no accident. I think someone needs me to protect this baby.
CLYDE: Protect her from who?
SARAH JANE: That's what we have to find out, before they come looking for her.

[Summerwell nuclear power station]

(A technician is walking through the turbine hall when static electricity starts playing over various metal surfaces. Then a big round energy ball appears, like the time travel balls in Terminator.)
CALEB: What is that? Oh, no.
(He is knocked down by the force as a fully clothed woman walks out of the ball. She walks over and puts her stiletto heel boot on his chest.)
MYERS: You're flesh. Good.
CALEB: Who, who are you?
MYERS: My name is Miss Myers, and you're going to help me find my child.
(She energy zaps his face.)

[Outside Sarah Jane's home]

SARAH JANE: I've scanned her. Now, give the readings to Mister Smith and hopefully he can give us a clue who she is and where she came from.
CLYDE: Received and understood. If Sparky blows her top again, we don't want her any where near Mister Smith.
SARAH JANE: Right. Time to get clear of Bannerman Road. Park should be safe enough.
RANI: Yep.
(Gita walks up the drive.)
RANI: Oh, no.
(Rani hands the carry cot to Sarah Jane.)
GITA: There you are, Rani. Oh, is there something you've not been telling us, Sarah?
RANI: Mum, there is a simple explanation.
GITA: Oh, you've started fostering, haven't you, darling? How wonderful. I always thought you made such a perfect mum to Luke.
SARAH JANE: Oh, thank you, Gita.
GITA: No wonder Luke couldn't get you on the phone. Bet she's a proper little handful. Aren't you? Aren't you, my
SARAH JANE: Yes, well, it was all a bit sudden, really. Yes, I practically opened the door and there she was, like she'd fallen out of the sky.
GITA: Oh, like that thing last night. What's her name?
CLYDE: Her name?
SARAH JANE: What thing last night?
GITA: I heard it on the local radio. A meteor landed in that wrecker's yard on Peel Road.
RANI: A meteor?
GITA: She must have a name, Sarah.
SARAH JANE: Sky.
GITA: Sky?
CLYDE: Yeah. Like she'd fallen out of it.
GITA: Oh, that's beautiful. Just like you.
(Baby Sky squeals, and all the car alarms in the street go off.)
GITA: Oh, flipping heck. First all the light bulbs, and now the car alarms. I'll catch up with you later.
(Gita leaves.)
CLYDE: An alien baby turns up on your doorstep and a meteor crashes on the same night? That's like a galactic coincidence.
RANI: We should check it out.
SARAH JANE: Absolutely. Clyde, give me my watch back. Mister Smith can analyse the scan later. We need to check out what's landed in the wreckers yard.
(She hands the carry cot to Clyde.)
CLYDE: What? What are you doing?
SARAH JANE: There's no baby seat. And the last thing I need is her blowing the car's electrics. And make sure Mister Smith stays out of harm's way.
RANI: You'll be fine. You're a natural.
SARAH JANE: Look after her, Clyde. I'm sure someone left her here because she's in danger. I'm relying on you.
CLYDE: Yeah, yeah. Don't worry.

[Control room]

MYERS: Take a power nap, boys.
(She zaps the workers, and they go to sleep on their feet.)
MYERS: I'm looking for a power surge in the area last night.
CALEB: Here. Exploding light bulbs.
MYERS: Bannerman Road. Don't worry, baby. Mummy's coming to get you.
(So is the thing from the wrecker's yard.)

[Wrecker's yard]

RANI: So you think Sky's in danger?
SARAH JANE: Why else would anyone leave her on my doorstep? What's got me confused is, who put her there?
RANI: The Doctor?
SARAH JANE: Oh, he'd never just leave her and take off without a word.
POLICEMAN: I'm sorry, you can't come through here. It's dangerous.
CELESTE: It's all right. Miss Smith is quite used to danger.
SARAH JANE: Professor Rivers!
CELESTE: Sarah Jane. Good to see you again. Come through, come through.
SARAH JANE: Thank you.
(In amongst the rubble.)
RANI: So where's the meteor?
CELESTE: Good question. We know a body impacted. Our seismographs at the Pharos Institute recorded it.
RANI: You don't really need a seismograph to see that, Professor.
SARAH JANE: Well, this was no meteor, and these energy traces don't look like any life form I've ever seen before.
CELESTE: You mean an alien?
RANI: Sarah Jane?
(Rani has found a big boot print.)
RANI: Whatever landed here last night, it had big boots.
CELESTE: Not only big, but heavy. Very heavy.
SARAH JANE: Whatever was here, there's something else now.
CELESTE: Something alien?
SARAH JANE: No, human.
(The tramp.)
SARAH JANE: Hello. No, no, no. It's all right. I only want to talk. After him. He might have seen something.
CELESTE: Oh, wait for me. I'm in Wellingtons!

[Hugo's home]

(The tramp runs through the piles of old cars into a home he has built for himself out of spare parts. It has a van door for a door.)
HUGO: I wasn't doing anything wrong.
RANI: What have you been living off, battery bunnies?
HUGO: They're for my radio. Not that it works since that great ruddy iron bloke dropped down last night.
SARAH JANE: Yeah, well, my name is Sarah Jane Smith. I'm a journalist. I just want you to tell me what you saw.
HUGO: The press? I'm not talking to you. I've seen what you put in the papers about people that have seen what I've seen. I do read them, you know.
RANI: It's all right. You can trust Sarah Jane.
HUGO: And I won't be able to listen to The Archers now.
SARAH JANE: Oh, well, what if I fix your radio for you. Will you tell me what you saw?
HUGO: With a lipstick? I'm homeless, I'm not brainless.
(Sarah Jane sonicks his transistor radio and it comes back to life.)
HUGO: It works. You fixed it. How did you do that? What sort of batteries do you use in that thing?

[Lounge]

CLYDE: And then the big bad Bane went bang, and everyone got covered in gunk.
(Gurgle.)
CLYDE: Don't, don't.
(His phone rings.)
CLYDE: This is Clyde. Speak to me. Thanks, Sparky. Flat as Jedward. No, no, don't cry, don't cry. Oh, come on, think, Langer. You're a born entertainer.
(So he tries mime, walking down pretend steps behind the sofa, etc.)
CLYDE: Say hello to Sid the Sleeve. Hello, Sky. Hello, Sid. What do you call a man who wears paper trousers? I don't know, Sid. Russell! Yeah, do you get it? No, too advanced, obviously. No, no, no. Don't cry, don't cry.

[Hugo's home]

SARAH JANE: Please, I just want you to tell me exactly what you saw.
RANI: You saw an iron man. Like a robot?
HUGO: Did I say he was a robot? No. I know what a robot looks like. I've seen Star Wars. This was a bloke. His skin was all metal.
SARAH JANE: Well, what happened?
HUGO: He fell out of the sky, and then stood up without a scratch on him and turned himself invisible.
RANI: Invisible?
HUGO: That's right. And I'm telling you this. He was armed to his flaming big steel choppers. If there's any more of them on the way, we don't stand a chance.

[Wrecker's yard]

RANI: A metal man? Is that even possible?
SARAH JANE: A biometalloid life form. Why not? It's a big universe. But now it's here and it's got to be looking for Sky.
(She tries her mobile phone.)
SARAH JANE: Oh, Clyde's not answering. Whatever it is, we've got to find it before it finds Sky.
RANI: Er, it's invisible.
SARAH JANE: Well, nothing's ever completely invisible.
CELESTE: Oh, there you are. What have I missed?
SARAH JANE: Celeste, do you have equipment on your van that can track an ultra high frequency electromagnetic signal?

[Garden]

CLYDE: Okay. No computers out here. No alien tech, no phones. You're safe. Oh, you like leaves. Leaves are good. Leaves are green. But not salad. Salad's green but it's also kind of yuck.

[Outside the Chandra home]

CALEB: Hello, Mister Chandra. We're from West London Power.
HARESH: This wouldn't be about all the bulbs blowing, would it?
CALEB: There was a freak power surge in Bannerman Road. We're visiting every house, looking for the cause.
MYERS: It needs to be isolated.

[Pharos Institute van]

SARAH JANE: Whatever crashed here emitted UHF electromagnetic radiation. That's what scrambled the radio. And whatever made those footprints might be able to make itself invisible, but it can't hide that energy trace.
CELESTE: There's something here. A regular UHF-ME pulse. And it's moving.
SARAH JANE: Right towards Bannerman Road. Rani, try Clyde again. Warn him. He has to get Sky away from there.
CELESTE: Who's Sky?
SARAH JANE: A defenceless child, and there's something very dangerous coming after her.
RANI: He's still not answering.
SARAH JANE: Come on. Thank you, Celeste.
CELESTE: Oh, my pleasure. Oh, and be careful.
SARAH JANE: Oh, I'm never careful. Always prepared.
(Rani and Sarah Jane leave. Celeste takes out her own lipstick.)
CELESTE: Zap! Zap, zap!

[Chandra home]

HARESH: Every light in the house went, and I don't suppose West London Power are going to reimburse me for those, are they?
MYERS: I'm afraid not. Mrs Chandra, do you have young children?
GITA: No. Just our daughter, Rani. She's seventeen, and very clever. She's going to be a journalist.
HARESH: What do children have to do with your company blowing our lights?
GITA: And you're going to blow a blood vessel, Haresh, if you don't calm down. Would you like a cuppa, my darlings? Now, our neighbour over the road, she's just fostered a baby. Earl Grey?

[Garden]

(The invisible visitor arrives in the road.)
CLYDE: And that's a tree, and oh, and this is grass. Cows eat grass. And they go moo and they make milk. You like milk, don't you. They also make steak. I like steak. Especially with chips. But they have to come from the chippie, definitely not from the oven. Oven chips are the work of bad cooking goblins.
(The gates appear to open on their own.)
CLYDE: Did you hear something? It was more like feel something.
(Footprints appear in a flowerbed.)
CLYDE: Oh, what made those?
(Clyde reaches out and knocks on something metal.)
CLYDE: Oh, this is not good.
(The metal man makes himself visible.)
CLYDE: Not good at all.
(And produces a gun.)
CLYDE: Not getting any better. Uh oh.
(He looks over its shoulder.)
CLYDE: Hi!
(Metal man turns. Clyde grabs Sky's carry cot and runs, dodging energy bolts.)

[Bannerman Road]

MYERS: Get in if you want the child to live!
CLYDE: Who are you?
MYERS: I'm her mother. Drive.
(Clyde gets into the back of the West London Power van. They zoom away with energy bolts bouncing off the back, then the metal man goes invisible again.)

[Chandra home]

GITA: Did you hear that?
HARESH: Don't worry. After the lights exploding and all the car alarms going off, it'll probably be the gas mains blowing up. Just a regular day on Bannerman Road.

[WLP van]

CLYDE: I don't know about you, Sky, but my mum always told me never to take lifts off strangers.

[Sarah Jane's home]

SARAH JANE: Clyde? Clyde?
RANI: He's not here.
SARAH JANE: Clyde!

[Attic]

SARAH JANE: Mister Smith, I need you now.
MR SMITH: Sarah Jane, what can I do for you?
SARAH JANE: I need you to find Clyde. Connect with every CCTV camera in London, every speed camera, whatever it takes, just find him.
MR SMITH: There are five hundred and twenty one thousand, three hundred and twenty one CCTV cameras in operation across London, Sarah Jane. It may take some time.
SARAH JANE: Just do it.
RANI: Maybe he's just taken Sky for a walk?
MR SMITH: He is at the Summerwell Nuclear Power Station.
RANI: Well, that didn't take long.
MR SMITH: I was lucky. It was only the ten thousand and fifty second camera I checked.
SARAH JANE: Who is that woman?
MYERS [on screen]: My name is Miss Myers.

[Summerwell nuclear power station]

CLYDE: That doesn't sound like much of an alien name.
MYERS: We don't spell it the same way. Now give me the child.
CLYDE: No, no, no. Answers first. What was that thing back there and why is it after the baby? And what are we doing here?

[Attic]

SARAH JANE: Come on.

[Summerwell nuclear power station]

MYERS: My child has a destiny. A destiny to change worlds, and that some will do anything to destroy.
CLYDE: Oh, what, like Tin Man back there?
MYERS: Hmm? The metalkind. The enemies of my species. Of all flesh.
CLYDE: But I don't get it. She's just a baby.
MYERS: How could you even begin to understand? You might be flesh, but you are Earth flesh. Just a few evolutionary twists from protozoa. Now give me my child!
CLYDE: I don't think so.
(Clyde runs off.)
MYERS: Get him!
(The man chases Clyde through the turbine hall and down some stairs. Clyde hides behind a pair of sleeping workers and the man runs on.)
CLYDE: Typical I'm in the middle of a nuclear power station and I'm carrying Baby Bang Bang.
MYERS [OC]: Find the boy!

[Outside the power station]

SARAH JANE: Looks like a back door to me.
RANI: See, why would that woman take Clyde and Sky to a nuclear power station?
SARAH JANE: I don't know, but you've seen the effect she has on anything electrical. Imagine what could happen there. Come on, we may not have much time.
(They leave the gate open for the invisible metal man to go through.)

[Summerwell nuclear power station]

MYERS: Oh, how perfect. You see, a baby will always find her mother. Give her to me.
CLYDE: No. What are you going to do to her?
MYERS: Take her home, of course. She's the saviour of my kind. She will be the stuff of legend. Now give her to me!
SARAH JANE: Clyde! Clyde, run!
(Then the now visible metal man turns up.)
RANI: Oh, boy.
METALKIND: The flesh whelp must be destroyed.
MYERS: No!
SARAH JANE: Get back. I won't let you hurt this child.
METALKIND: She is no child. She is a weapon.
MYERS: And she is unprimed. She isn't ready for this. You have doomed us all!
(Sky starts crying. Energy plays around her carry cot.)
RANI: What's going on?
SARAH JANE: Sky's energy, it's flooding out of her.
MYERS: Yes, the weapon is priming itself. Your presence has activated it. The doom of the Metalkind is come!
(Sky transforms into a young girl.)
SARAH JANE: Sky?
