explanation.
[Intercom Signal]
McCoy to Captain Kirk.
Captain's presence
for examination is requested.
Can't it wait,
Bones?
Your orders, Jim.
You're the last one.
What do you read so far?
Can we discuss it here?
On my way.
Mr. Spock,
you have the con.
What is it?
Tell the captain
what you told me.
Somebody's opened
all the medical supply cabinets.
Anything missing?
Just disordered,
as though someone
had picked up everything
and examined it.
Thank you.
Lie down, Jim.
Well, that fits in
with other disturbances.
Bones, what did
your readings show up
on the other men?
All perfectly normal.
Whatever happened
to Compton
apparently had no effect
on anyone else.
Anyone report any unusual experience
since beaming?
No. There's no mention of it.
[Buzzing Tone]
I'm not finished yet.
Hold on.
Bones...
could something be
making me hallucinate?
What do you mean?
I mean that twice before
something touched me.
And there was nothing there.
And it's just
happened again.
Could I be... imagining it?
Well, physically
there's nothing wrong with you.
But am I
hallucinating?
I'd say no.
Then we did
beam something aboard.
[Buzzing]
Something has
invaded the ship.
[Intercom Signal]
Kirk to Spock.
Come in. Spock, come in.
Captain, I have a reading
from Life Support Center--
- [Static]
- Spock, I can't hear you.
Is there a malfunction?
[Uhura] The intercom system
is breaking down rapidly.
Lieutenant,
ship wide order--
use communicators
instead of intercom.
Issue phasers
to all crew members.
Spock, repeat.
I have a reading
from Life Support Center.
Alien substances
being introduced.
Meet me there
on the double.
Spock?
It's a force field, the nature
of which I'm not familiar with.
I'm getting readings
of an alien presence
similar to those obtained
on the planet's surface,
but with no exact location.
Phasers on stun.
Sweep the area.
It would seem, Captain,
that they intend to allow
only the two
of us to enter.
I should advise caution.
What is it?
Unknown, Captain.
But it is evidently a device
of alien origin.
Hooked into
the life support.
Designed to affect it.
Life support
is still operating.
I would say that the installation
is incomplete.
Disconnect it.
[ZZZZ]
Destroy it.
That was no force field.
Something shoved me back.
They're in here.
You!
What are you doing
in my ship?
Show yourselves!
[Buzzing]
[ZZZZ]
[ZZZZ]
It seems that we may look
at it, Captain,
but that is all.
A show of strength.
Yes. Evidently,
they're convinced
that we can do nothing
to stop them,
and they wish
to impress upon us
what they can do to us.
Have your readings
been fed into the computer?
Affirmative.
Read out.
Computer,
analyze and reply.
Have we been invaded?
Affirmative.
Nature and description
of enemy forces.
Data insufficient.
Number of enemy forces.
Data insufficient.
Purpose of the invasion?
Immediate purpose--
seizure and control
of Federation Star ship Enterprise
and crew.
Data insufficient
for determination
of end purpose.
Is there a connection
between this
and Compton's
disappearance?
Data insufficient.
Are we at present
capable of resisting?
Negative.
Your recommendation?
If incapable of resistance,
negotiate for terms.
We will not negotiate.
Do you concur?
Aye.
Mr. Spock?
Your recommendations,
Captain?
Yeoman, is that
coffee available,
or have those circuits
been damaged as well?
My recommendation?
Make them
take the next step.
[Buzzing]
Spock?
Captain.
Would you mind
explaining--
Who are you?
Deela.
The enemy.
You're the enemy?
Yes.
You beamed me aboard yourself
when you came up.
A ridiculously long process,
but I've
taken care of it.
What have you done
with my men?
Nothing.
Nothing?
Mr. Spock?
Scotty.
This is nothing?
There's really
nothing wrong with them.
They are just
as they have always been.
It's you
who are different.
Lieutenant.
Sulu.
This is nothing?
They
