Stargate SG-1 (1997–2007): Season 3, Episode 14 - Foothold - full transcript

After a vain search for the Harsesis boy on an unexplored planet, SG-1 is told there is a chemical leak and gets sedating injections in the infirmary. In fact star-base has been taken over by body-snatching aliens, as Teal'c and Sam discover, who are immune because of his symbiont and her Jolinar-remnants. Teal'c is captured while giving Sam the chance to escape; she meets with Colonel Harry Maybourne, who alas believes and brought the alien-possessed Jack and Daniel, who claim it's paranoia caused by the leaked chemical; during a flight back, Sam is able to see trough the game because of a 'flicker' and discovers it's done by two electronic devices to assume a human shape and voice. Meanwhile the real Jack and Major Paul Davis awake in an organic web where every human is tied into tentacles, soon meeting up with Sam and liberating Teal'c, in a hurry to try Sam's sound-idea before Maybourne sends in troops with orders to shoot and kill...

Incoming traveller.

Ah, Jesus!

- Welcome back, SG-1. - Thank
you, sir. It's good to be back.

- You're overdue. - Bit
of a wild-goose chase, sir.

The remnants of a temple we discovered
led me to believe we'd found Kheb.

The planet Sha're told me about.

However, there was no sign
of Amaunet's Harsesis child.

Just rain.

Much rain. Wind, lightning, hail.

Did I mention the rain, sir?

Report to the infirmary.

I think we'd all like to change first.
I have mushrooms growing out of...

Attention all levels. Stand by for
contaminated materials transfer.

Infirmary. Yes, sir.

- Infirmary?
- What?

I'm escorting you as a safety precaution.
There's a big chemical spill on level 23.

- What kind of chemical?
- Tetrachloroethylene ruptured.

- Ruptured?
- The entire level's been sealed off.

Hazmat team's cleaning it up now.

- What?
- There's no danger, sir.

Thank you.

Loosen your belt, please, Colonel.

How's a needle in my butt
gonna get water out of my ears?

It isn't. Come on, sir. You
know this is standard procedure.

We should rethink this procedure.

So, Daniel, in our
galactic meanderings, ...

. . if we happen to stumble
across this Narcissus child...

- Harsesis.
- We're still talking about a baby, right?

- What?
- What?

Attention. Contaminated
material transfer in progress.

Please remain at
yourpost until notified.

Listen, really jam it in this time, OK?

If Sha're's child is born with all
of the knowledge of the Goa'uld, ...

. . it should be able to communicate
at a much younger age, right?


- Daniel?
- Just relax.

Let's begin.

It has something to do
with the alien symbiote.

It took an extremely large dose just
to sedate him in the first place.

- What is the problem with the human?
- Her body chemistry has been altered.

It is related to her prior infestation
by the dominant parasitical species here.

- Is there a way to compensate?
- I have not found it yet.

Place them in a holding cell. Once the
invasion is complete, study them further.

Only then will we know if this is a
viable new home world. Come with me.

Take that one first.

Attention all levels. Contaminated
material transfer in progress.

Remain at yourpost until notified.

Contaminated material
transfer in progress.

- 23?
- No, this one's going to 16.


Major Carter, there is little time.

Are you capable of standing?

Oh. I feel sick.

You are suffering from
the effects of a sedative.

What? What's going on?

- What the hell happened to them?
- They are not who they appear to be.

There's been an alien
incursion within the SGC.

A what?

Dr Fraiser and General
Hammond spoke of a procedure...

. . which had failed to work upon
both of us. They spoke of invasion.

Wha... ? How does that add up to aliens?

I saw two of them in their natural
form. Truly, they are alien.

What about the Colonel and Daniel? We
have to know what's happened to them.

Come in.

- It's locked.
- It's not locked.

- What about this chemical spill?
- I believe it to be a subterfuge.

Not one camera's operating on level 23.

- Incoming traveller.
- Try punching up the gate room.


The O'Neill and Daniel Jackson we know
would not welcome aliens so blithely.


How do we know we're the
only ones not replaced?

There's no way of knowing, but
if Hammond has been compromised...

Then we can't trust
anyone in the mountain.

Alert General Hammond.

The base was designed to
keep people out, not in.

- If we can make it
to the south gate...

- Our escape has been detected.
- We won't make it out this way now.

I will purchase time for
you to depart this mountain.

Keep 'em busy as long as
you can. I'll come back.

Of that I'm certain.

Airport shuttles are located in the blue
zone, hotel shuttles in the green zone.


This is Major Samantha Carter.
We have a foothold situation.

Major Carter? Where are you?

I can't tell you that, sir.

There's an outdoor cafe
outside NID headquarters.

- In DC?
- Four o'clock.


- I'm gonna need a little more than that.
- I repeat, we have a foothold situation.

You're outside your
appropriate chain of command.

I have reason to believe
that may be compromised, sir.


Hey, Teal'c, how are you feeling?

You, uh... went a little crazy
on us, so we had to sedate you.

- You remember what happened?
- I do not.

SG-1 was exposed to chemical
fumes from the spill.

You became delusional and attacked
several people trying to escape.

Teal'c... glad you're awake. Has
Dr Fraiser explained the situation?

She has.

Good. We're hoping you can
tell us where Major Carter is.

She also had an adverse
reaction to the chemical.

One of the side effects is
hallucinations, paranoia.

Your symbiote protects you from a lot,
but apparently not tetrachloroethylene.

Where is she?

I do not know.

Teal'c, if she doesn't receive medical
attention soon, she's going to get worse.

I won't lie to you
- she could die.

- Hi. Can I get you some coffee?
- Please.

Thank you.

So, you came to the one
person you don't trust.

I don't know how far up
the infiltration goes.

It may be contained within the SGC, but
if General Hammond was compromised...

He sounded fine to me on the phone.

- What?
- He called me, Major.

- Calm down. He's concerned for you.
- I told you we had a foothold situation.

Major, a chemical spill causing paranoid
delusion is more plausible to me...

- . . than aliens taking over the SGC.
- My God.

You don't think I can tell
the difference between the two?

- What was I thinking?
- Oh, hi, Carter.

Maybourne, you are an
idiot every day of the week!

Why couldn't you have
just taken one day off?!

That's insubordination, Major.

For crying out loud,
Maybourne, cut her some slack.

- She's not exactly herself.
- And neither were we.

Sam, believe me, I know what
you're feeling. It's the chemical.

I don't believe it.

All right. Exactly what are the
side effects of this tetrachloro...

. . ethyl mermaline stuff?

Hallucination, delusion.

- Paranoid delusion, I think, but go on.
- Look, I know what I saw.

We were affected by the fumes
the moment we got in the elevator.

Didn't even realise it was happening.

I vaguely remember having some
water in my ear, that's it.

- Dr Fraiser injected me with something.
- She was trying to sedate you.

She didn't give enough to Teal'c.
He sprung you and off you went.

He's fine, by the way.

Beat the crap out of a
couple of SFs, but he's fine.

We're telling you the truth, Sam.

You should have followed procedure.

I fully intend to return with you just
to make sure everything's all right.

And you agreed to that?
Shouldn't that tell you something?

I wouldn't tell them where we were
until they agreed to my inspection.

- You have no idea what you're going into.
- I can take care of myself, Major.

If I don't report back in a few hours, you
can rest assured that action will be taken.

We just want you to come back
so Fraiser can check you out.

- You're asking?
- We're asking.

So, I have a choice.
I can walk away now?

- Yes.
- No!

- Maybourne.
- You will accompany us back to the base.

- If you resist, you will be handcuffed.
- No, she won't.

This is very touching, but this
conversation in this public place...

. . is evidence that Major Carter
is something of a security risk.

What's the matter with you?

It's starting to wear off, isn't it?

You're starting to think straight.
That's exactly what happened to me.

I'm so tired.

We're gonna go now.

I'd like you to come
with... but it's up to you.

All right.


Good. Plane's waiting.

After you, Major.

Maybe you'll remember
something later, son.

Please release me from these restraints.

I'm sorry, Teal'c. There's
still a chance you could relapse.

Three of the men you
attacked have concussions.


You're certain she's been located?

Very well.

Then we may begin
experimenting immediately.

Your tax dollars at work. Cosy
jet you got here, Maybourne.

You've alerted General
Hammond to expect me?

Oh, yes. He's awaiting your thoughts.

- So how exactly is Teal'c?
- Oh, well, you know Teal'c.

Is the chemical spill
completely cleaned up?

As of this morning the Hazmat
team had gotten the last of it.

But they're gonna keep level 23 sealed off
until they can figure out what happened.

Carter? What are you doing?

Don't move.

- Put the gun down.
- She's hallucinating again.

What the hell is that?

Sit down.

Look out!

- Go check the pilot. He's one of mine.
- You first.

Good enough? I'll
keep an eye on him. Go!


- What is that?
- I don't know.

- What is that damn thing?
- I told you I didn't know that Jack was...

Tell us how that thing works.


Hold on a second.

So, this is how they look like us.

Where's the real Daniel?
ls he still alive?

You can talk to us now,
or to my colleagues later.

Either way, we'll find out
the information we need.

Sit down!

It works.

It only creates an image. I couldn't
hear Daniel's thoughts or anything.

- That must be what this one does.
- Put that thing down, Major.

- What caused their images to blink out?
- They were just sitting there.

Something interrupted both signals at
the same time. We should figure out what.

We were levelling off.
Uh, cabin pressure.

This is electronic. It
was more like interference.

Noise from the engines, maybe. If we can
replicate the conditions, we can find it.

All right.

Sorry, sir.

What the... ?

Who's that?

Major Davis.

Colonel O'Neill.

What's going on? How
did we get like this?

You're asking me?

Hook him up.


I thought the sedative
might be interfering.

The symbiote is quite resilient.

- So is he.
- Put him back in the holding cell.

Major Carter's on her way
back. She may be less resistant.


The latch for that thing is...

- You found it.
- Yes, sir.

If there's another Fraiser, my guess
is there's another you and me too.

Why are we the only ones awake?

Maybe, uh, maybe a malfunction.

- Colonel, what are you doing?
- I'm gonna wake her up.

- Do you think that's such a good idea?
- Well, it's an idea.

Maybe they didn't hear that.

Excuse me.

That was weird.

A nice alien like you's gotta carry a...

- Hello.
- What about the other thing?

The other thing.


She's just an alien.

Just an alien.

Whoa, whoa.

Yeah, that's an alien all right.

Why don't you find
something to tie it up?




It's you?


It's good to see you.

Oh, my God. I figured they were keeping
you alive in order to access your mind.

Whoa! Hey.

- Who are you?
- Sir?

Oh, sorry.

Major Carter.


Well, in that case, it's
good to see you, too.

Every one of the people in this room
has been duplicated by the aliens, sir.

Uh, noticed that.

The procedure didn't
work on me or Teal'c.

We escaped, but Teal'c's been captured.

- Where's he?
- I haven't had time to find him, sir.

- Maybourne's forces are moving in soon.
- Maybourne? How'd he get... ?

- I called him.
- Willingly?

In 29 minutes those forces are
gonna break down the front door...

. . and shoot anything that
resists. We need to get our people.

Yeah. I pulled that headband thing off
of Fraiser. Her evil twin came running.

- Well, how did you two get free?
- We just woke up.

That must have happened
when I killed you.

I'm sorry?

I killed the aliens
impersonating both of you.

- And they don't know you did this?
- I don't know, sir.

There's a specific tone that
will disrupt these devices.

- The machine's in my lab.
- Go.

- Sir, we're gonna need more weapons.
- Armoury.

Head on back to 23. Keep
an eye on our people.

Yes, sir.

I've come for the bald prisoner.

You will come with me.

I will submit to no further experiments.

Oh, but you will.

- I'll take it from here.
- I can't allow that, sir.

Oh, but you can.

Colonel O'Neill, I presume.

What gave it away?

That's it.

General Hammond.

General Hammond to the control room.

- Sure you're up to this?
- As always.

You're an animal.

- What the hell was that?
- Colonel! On your six.

- What's going on?
- I don't know. They just ran.

- Perhaps there's an evacuation.
- We can't let that happen, sir.

- Why not?
- They've accessed our minds.

They know everything about us.

- Everything?
- Everything.

Close that iris.

I can't, sir. It's overridden.
I'm shutting down the gate.

Everyone, freeze!

- What happened? They self
- destructed.

Their destruction
appears to be complete.

That's a lot of damage.

Coat of paint... little touch-up...

It'll be fine.

I've ordered P3X-118 locked
out of our dialling program.

The human counterparts of those
aliens woke up spontaneously.

We're assuming the signal
stopped when they left.

Those who escaped still have knowledge
obtained from being linked to your minds.

That's creepy.

We've changed all our
codes. That's all we can do.

How did this happen? The aliens came
through the gate impersonating SG-6?

We rushed them to the infirmary. We
don't remember anything after that.

Hammond asked me to come,
but wouldn't say why.

Presumably their next step
after the SGC was the Pentagon.

A high-frequency blast
every time a team returns...

. . should prevent it from
ever happening again.

Colonel Maybourne.

Good save.

I thought you'd like to know the
alien posing as Dr Jackson expired.

What of the aliens not
caught in the explosion?

We're guessing they were linked to
their leader when he self-destructed.

What about the aliens that escaped?

We'll never know. We'll have to
hope the same thing happened to them.

We appreciate your help on
this matter, Colonel Maybourne.

Credit Major Carter. I do.

Well, I'm, uh... sure
we'll see each other again.

That'd be nice, Harry.
