Enterprise.
If you need me,
call and I will appear.
Our new goal
is Marcos 12.
It is our new beginning.
We must not falter.
Go to your stations.
Mary, you remain
here with me.
Helmsman,
disregard what you see
on the screen,
what you think
you see on the screen.
Set a course
for Star base 4.
- Helmsman, did you hear me?
- Yes, sir.
Lieutenant Uhura,
contact Star base 4.
Tell them we're bringing
the children there.
Tell Starfleet Command
I suspect them
of being alien
in nature,
and I want a thorough
investigation made
upon our arrival.
Aye, aye, sir.
Lieutenant ...
what are you
staring at?
I see my death.
A long ... death.
Disease and pain.
I see my death.
- There's nothing there.
- Oh, God.
Captain,
don't let it be.
Mr. Spock, you make
the call to Starfleet.
Mr. Sulu, I ordered you
to change course.
Mr. Sulu --
Captain, stay away
from the controls!
If you touch them,
we'll be destroyed.
Mr. Sulu,
there's nothing there.
Captain, why are we
bothering Starfleet?
That was an order,
Spock.
This bridge is under
complete control.
- Complete --
- There is no need.
Take a look
around you.
I cannot obey
your order, Captain.
Take Mr. Sulu
to his quarters.
He is relieved
of duty.
[Garbled Speech]
[Garbled Speech]
From the --
Confine them to quarters.
Did you hear me?
Did you hear me?
Captain ...
we must get off
this bridge.
Yes, we must.
I'm losing command.
I'm losing
my ability to command.
I'm losing
the Enterprise.
I'm losing command.
I'm losing
the Enterprise.
My ship is
sailing on and on.
I'm alone.
Alone.
Alone.
I'm losing command.
Captain.
I've lost command.
I've lost
the Enterprise.
Captain Kirk.
Jim.
I've got command.
I've got command.
- I've got command.
- Correct, Captain.
Where to, Captain?
Auxiliary control,
my Vulcan friend.
This ship
is off course.
Scotty.
I want you
to override
the bridge
navigation system
and plot a course
for Star base 4.
I can't do that, sir.
Why not?
These are very
sensitive instruments.
I will not have you upset
their delicate balance.
We would all be lost,
forever lost.
Go away now.
Go away
or we'll kill you.
Scotty,
listen to me.
The Enterprise has been
invaded by alien beings.
Its destination
is Marcos.
If we take it there,
millions will die
the way they died
at Triacus.
Oh, I'm all right,
Spock.
My beast is finished.
It won't return.
Captain, so long
as the children are present,
there is danger.
They are the carriers.
Spock, they're not
the alien beings.
They're children
being misled.
They are followers.
Without followers,
evil cannot spread.
They're children.
Captain,
the 430 men and women
on board the Enterprise
and the ship itself
are endangered
by these ... children.
They don't understand
the evil
that they're doing.
Perhaps that is true,
but the evil
that is within them
is spreading fast,
and unless we can find
a way to remove it ...
we'll have to kill them.
Captain Kirk.
What is it, Ensign?
I have been instructed
to place you and Mr. Spock
under arrest.
By whose order?
Starfleet Command, sir.
Where did you hear
this order, Ensign?
Now, listen to me.
This order is false.
I want you and your men
to return to their stations.
I'm sorry, I must insist
you and Mr. Spock
come with me
to the detention section.
Ensign,
listen to me.
Do not force me
to kill you, sir.
I will if I have to.
Will you come
peacefully, Captain?
Ensign, listen to me.
This is a false order.
I have never disobeyed
an order, Captain.
I know that, Ensign.
You have never
disobeyed an order,
but an alien being
is aboard this ship.
I will not disobey!
I cannot disobey!
Disobey this order!
Starfleet Command
supersedes your order, sir!
Ahh ...
Enough.
Take these men
to detention
then join me
on the bridge.
The Enterprise
will never reach Marcos 12.
We will not
be landed there.
The crew will take us.
The crew believes.
The crew ...
