[Kirk] Captain's Log, star date, 5693.2.
The Enterprise is approaching
the last reported position
of the star ship Defiant,
which vanished without trace three weeks ago.
We are in unsurveyed territory.
Captain, we are registering very curious readings
from all sensors.
According to our instruments,
space itself is literally breaking up.
There is no known phenomenon
which would account for these readings.
What about sensor failure?
Negative. I've run a complete check on all systems.
Captain, we're losing power in the warp engines!
We can barely read it, but I don't like it.
I cannot find the cause.
Visual detection of an object dead ahead.
How about it, Spock?
There is virtually no sensor contact.
No mass analysis. No trace of radiation.
We see it, but our sensors indicate it is not there.
Mr. Sulu, impulse engines only.
Close to transporter range.
Aye, aye, sir.
Lieutenant, open up a hailing frequency.
I've been trying to raise them.
Just within transporter range, sir.
Good. Maintain position.
Mr. Spock, Mr. Chekov, come with me.
Dr. McCoy, report to the transporter room immediately.
- Scotty, you have the con. - Aye, sir.
Locked in on the Defiant bridge, sir.
Space-- the final frontier.
These are the voyages of the star ship Enterprise.
Its five-year mission--
to explore strange new worlds...
to seek out new life and new civilizations ...
to boldly go where no man has gone before.
Has there ever been a mutiny on a star ship before?
Absolutely no record of such an occurrence, Ensign.
The captain's neck is broken.
The ship is still functioning, Captain.
It is logical to assume the mutineers are somewhere aboard.
Use the ship's sensors to locate them.
Kirk to Enterprise.
Scott here, sir.
Prepare to beam over a full security squad on my orders.
Aye, aye, Captain.
Captain, there's no sign of life aboard this vessel.
Odd, Mr. Spock. Very odd.
Spock, you stay here with me.
Chekov, get down to engineering and life support systems.
Dr. McCoy, check out the sick bay.
Kirk to Enterprise. Cancel the security squad
and stand by for further instructions.
Aye, aye, Captain.
I can't get an accurate fix
on the Defiant, Mr. Scott,
but I know it's drifting away from us.
Shall I correct for range, sir?
Aye, I think you're right.
Keep us within beaming range, but not too close.
- Captain. - Report, Mr. Chekov.
Just like what I found in life support.
Get back up here.
Kirk to McCoy.
Bones, can you tell me what they all died of?
I'd say these people killed each other.
You heard correctly, Jim.
These people killed each other.
Could mental disease have infected all of the crew?
According to the ship 's log, the medical surgeon down here
didn't even know what was going on.
The best I can do is get all the readings I can get
and analyze them later.
What the devil?
[Kirk] Bones, what is it?
Bones, what is it?
Jim, this ship is dissolving.
My hand just passed through a man and a table.
Get up here on the double!
Mr. Scott, the Defiant,
it's starting to disappear.
Bridge to transporter room!
Transporter room, O'Neil here.
Got that transporter working yet?
No, sir. Not yet.
Take over, Mr. Sulu. I'll be in the transporter room.
Aye, aye, sir.
Captain, the Defiant's sensors correspond
with an extremely high degree of correlation
to those of the Enterprise.
You mean what happened to the Defiant
might be happening to the Enterprise?
Kirk to Enterprise. Mr. Scott.
Mr. Scott, stand by to beam us back.
I can't, sir. Not all at once.
Why not? What's happened?
That ship you're in is fading,
and it's ripping the innards out of this one.
It's jamming our transporter frequencies.
I've only got three working.
I'm not sure of those.
One of you has got to wait.
Chekov, McCoy, prepare for transportation.
You, too, Spock.
Request permission to remain, Captain.
I could be completing the data.
Captain, there is a chance---
I know the chances.
Mr. Spock, don't argue.
Get back with the information.
I'll be right there.
Scotty, energize transporter.
The Defiant Just vanished.
That's it. I've done all I can.
There's nothing out there to grab and bring in.
When that ship went, it took the captain with it.
[Digitized Voice] Computer working.
Compute the next period of spatial interphase.
Next interphase 2 hours, 12 minutes.
2 hours and 12 minutes?
That power leak unbalanced the ship and she's drifting.
I can't hold her in place that long.
We must try. The fabric of space is very weak here.
If we disturb it,
there'll be no chance
of retrieving the captain alive.
I don't understand what's so special
about this region of space.
Well, picture it this way, Mr. Chekov.
We exist in a universe
which coexists with a multitude of others
in the same physical space.
At certain brief periods of time,
an area of their space overlaps an area of ours.
That is a time of interphase,
during which we can connect
with the Defiant's universe.
We will be able to retrieve the captain
at that time, won't we?
However, the dimensional structure of each universe
is totally dissimilar.
Any use of power disturbs it.
If we are not extremely careful,
we shall lose the captain and become trapped ourselves.
And die like him?
[Voice Echoes] Chekov!
- Aah! - Chekov!
Security guards to the bridge.
What happened, Mr. Spock?
I was attempting to explain to Mr. Chekov
the nature of our problems in this situation
when he attacked.
Did anyone notice anything peculiar
in his behaviour before this?
I think he had several spasms of pain.
Did he seem to be getting hysterical?
Doctor, he seemed more angry than frightened.
He had no cause to be angry.
Take Mr. Chekov to sick bay.
Put him under restraint.
Lieutenant Uhura is correct.
There was murderous fury in Chekov.
The same fury which was evident in the Defiant.
That's what I was afraid of.
Whatever drove the Defiant's crew to murder each other
could be communicable.
Is there anything you need to isolate the cause?
By the way, Mr. Spock,
it might be a wise precaution
to put some distance between us
and the Defiant.
If we are to recover the captain,
we must not move.
How long will that take?
Approximately two hours before the attempt can be made.
Spock, are you sure that Jim is still alive?
If the captain was caught
in our transporter beam
when the Defiant phased out,
it's possible he was spared the shock of transition
However, if we are to recover him,
we must catch him at the precise moment
during the next interphase,
or he will die.
There can be no margin for error.
His environmental unit
can provide breathable air
for no more than 3.62 hours.
Mr. Spock, a vessel approaching
on an intercept vector.
Status, Mr. Sulu.
Range-- 200,000 kilometres.
Velocity-- 0.51 "C."
Lieutenant Uhura, signal red alert.
All decks, go to red alert!
Security patrol. Will do.
[Security Officers Over P.A. System]
Security patrol. Will do.
They've stopped dead, sir.
Range-- 90,000 kilometres and holding.
I'm receiving a visual signal.
Transfer to main viewer.
I am Commander Loskene.
You are trespassing
in a territorial annex of the Tholian Assembly.
You must leave this area immediately.
Spock, in command of the Federation star ship Enterprise.
According to the Federation, this area is free space.
We claim this territory
and are prepared to use force, if necessary,
to protect our property.
We're not interested in your display of force.
The Enterprise is responding to a distress signal
from one of our ships
and is currently engaged in rescue operations.
Do you wish to assist us?
I find no evidence of a disabled ship.
My instruments indicate
ours are the only two vessels in this area.
The other ship is interspatially trapped.
It should reappear in 1 hour and 53 minutes.
We request you stand by until then.
Very well, Enterprise.
In the interest of interstellar amity,
we will wait precisely 1 hour and 53 minutes,
but be correct.
We do not tolerate deceit.
If we could only find the proper filtering agent,
we might be able to solve this problem.
Negative. It's the third failure.
Nurse, take this sample and run an analysis on it.
Bridge to transporter room.
Transporter room here.
Ready for interphase in 20 seconds.
Thank you, nurse.
I want to have some checks run on this man.
Lock on to Captain Kirk's coordinates
and prepare to bring him aboard, Mr. Scott.
Bring him aboard, Mr. Scott.
Captain Kirk is not on his designated coordinates, Mr. Spock!
Well, keep trying, Mr. Scott.
Lieutenant Sulu, evaluation.
Sensor readings are not corresponding
to those we received the last time we saw the Defiant.
It's possible that Tholian entry into the area
has disturbed the space,
and if that has occurred...
McCoy to bridge.
Has the captain been beamed aboard yet?
When is that interphase going to happen?
Theoretically it already has happened, Doctor.
However, the ship's sensors are not responding as predicted.
You had the thing timed out.
I did, Doctor.
The space was disturbed by the Tholians.
You don't know whether you'll recover the captain?
Not at this interphase.
I shall have to recalculate
to determine when the next interphase occurs.
They don't take place at regular intervals.
You can't wait.
We've had another case like Chekov.
I've confined my orderly to sickbay.
I have confidence that you will soon isolate the cause
and prevent further spread of the affliction.
The disease is not transmitted by the men,
the cause is the area of space we're in.
It's affecting the whole crew.
The molecular structure of the brain tissues
in the central nervous system are distorting.
The madness that affected the Defiant's crew
will soon happen to the Enterprise.
You've got to get this ship out of here!
We're being fired upon.
The renowned Tholian punctuality.
Damage control report-- Minor structural damage
to sections A-4 and C-13.
Engineering, hold power steady
and cut off all unnecessary expenditures.
Mr. Sulu, divert all but emergency maintenance power
to the shields.
Sir, that will reduce our phaser power by 50%.
Scott to bridge!
I know you don't like to use the phasers,
but you've got to do something about that ship!
Lieutenant Uhura, open a channel to the Tholian ship.
Mr. Sulu, lock in phaser tracking controls.
Phasers locked in, sir.
There's no response on any frequency, sir.
What's the use of this battle?
You've lost Jim. Take us away.
Ready, Mr. Sulu?
Engineering, status report.
That hit from the Tholians
fused our power supply converters.
I can't do a thing with the Enterprise.
She's bound to drift,
maybe right through that doorway out there.
Can you estimate minimum time required for repair?
I don't even know if she can be repaired.
Are you satisfied?
Why did you do it?
The decision to fight was logical.
Lack of time prevented any other course of action.
The Tholian ship had to be disabled.
You should've known what could've happened
and done everything in your power
to safeguard your crew,
that's the mark of a star ship captain, like Jim.
I hardly believe this is the time for comparisons.
Please go to your laboratory
and search for an antidote to the effects of this space.
That's your primary task, since we must remain here.
something has Just entered sensor range.
It's another Tholian, sir.
Loskene must've contacted them
when trying to intercept us.
Lock in remaining phaser power?
Negative. Lieutenant Uhura,
open a channel to the approaching vessel.
They're refusing reception. I can't--
Distance, Mr. Sulu.
Just beyond phaser range, sir.
What is that?
Mr. Sulu, I shall run an analysis on those filaments.
Tie in all sensors to the library computer console.
There's no analogy to this structure
in Federation technology.
It is, however, an energy field,
and if the Tholians are successful
in completing this structure
before we have completed our repairs...
we shall not see home again.
Doctor, your last report on an antidote
on the effects of this space was negative.
It's still negative, Mr. Spock.
Tharagen is the most promising substance tested so far.
The urgency requires your attention in the laboratory.
My staff is working around the clock.
My being there will not affect any of the tests.
This service requires my personal attention, Mr. Spock.
A few hours ago,
the captain elected to remain on board the Defiant
so that three members of his crew
would have the best chance
of returning safely to the Enterprise.
His concern was not only for them,
but for all the members of the crew of this ship.
You all know the sequence of events.
You were fired upon by the Tholian ship.
At that time,
Captain Kirk may have been alive.
I deemed it necessary to return the Tholian fire
for the safety of the Enterprise.
The Tholian ship has been disabled.
But as a result of the battle,
we must accept the fact
that Captain Kirk is no longer alive.
Take him to sick bay.
Put him in restraint.
I shall not attempt
to voice the quality of respect and admiration
which Captain Kirk commanded.
Each of you must evaluate the loss
in the privacy of your own thoughts.
There is a duty to be performed
in the captain's quarters,
which requires our presence.
It can wait, Doctor.
My duties require my immediate presence on the bridge.
The captain left a message tape.
It was his order that it be reviewed by both of us,
should he ever be declared dead.
You have just declared Jim dead.
It will wait for a more suitable moment, Doctor.
Why? Are you afraid it'll change your present status?
The mental and physical state of this crew
are your responsibility, Doctor.
At the moment, they are your top priority.
The captain's last order is top priority,
and you will honour that order before you take over.
He was a hero,
yet his life was sacrificed for nothing.
What would have given his death meaning
is the safety of the Enterprise.
Now you've made that impossible.
We came here for a specific purpose, Doctor.
Maybe not the same one.
I really came here to find out why you stayed and fought.
The captain would have remained to recover a crew member
at the risk of his own life or even his own ship.
Yes, he would, Mr. Spock,
but you didn't have that decision to make.
What would you gain by fighting the Tholians?
You could have assured yourself of a captaincy
by leaving the area. But you chose to stay. Why?
I need not explain my rationale to you
or any other member of this crew.
There is a margin of variation in any experiment.
While there was a chance,
I was bound legally and morally
to ascertain the captain's status.
You mean to be sure if he was dead.
Well, you made certain of that.
That is enough, Doctor.
We both have other things to do.
Yes, I have something to do.
If the crew is to survive,
I have to find an antidote
to this space you've locked us into.
You will return to your duty
as soon as we've discharged our responsibilities here.
There's no hurry, Mr. Spock.
The antidote probably doesn't concern you.
Vulcans are probably immune,
so just take your time.
I must admit I don't understand you, Spock,
but I just can't believe
that you would want Jim's command.
You must know that if you get us out of this situation,
they'll pin a medal on you
and give you command of the Enterprise.
Doctor, I am in command of the Enterprise.
I would like to remedy that situation.
If you believe I have acted irregularly,
then relieve me of duty.
That is your prerogative as medical officer of this ship.
since you are playing this tape,
we will assume that I am dead,
that the tactical situation is critical,
and both of you are locked in mortal combat.
It means, Spock, that you have control of the ship
and are probably making
the most difficult decisions of your career.
I can offer only one small piece of advice,
for whatever it's worth--
Use every scrap of knowledge and logic you have
to save the ship.
But tempery our judgment with intuitive insight.
I believe you have those qualities,
but if you can't find them in yourself,
seek out McCoy.
Ask his advice.
And if you find it sound, take it.
Bones, you've heard what I've just told Spock.
Help him if you can,
but remember, he is the captain.
His decisions must be followed without question.
You might find that he is capable of human insight
and human error.
They are most difficult to defend,
but you will find that he is deserving
of the same loyalty and confidence
each of you have given me.
Spock, l... uh...
It does hurt, doesn't it?
What would you have me say, Doctor?
[Scotty] Mr. Spock, we have a readout
on the Tholian tractor field.
I think we can estimate its approximate completion time.
I shall be there shortly.
Doctor, I believe we each have
our respective tasks to complete
before the Tholians complete theirs.
Captain Kirk, we thought you were--
I've just seen the captain.
Of course you have. We'd all like to--
He's alive, Doctor.
Believe me, I did see him.
You're going to sick bay.
Doctor, I'm not going mad.
I did see Captain Kirk.
I've got to get...
to Mr. Spock.
Scott to Captain.
Scott to Captain.
Proceed, Mr. Scott.
One of our crewmen Just went berserk.
Report all symptoms noted prior to the attack.
- Dr. McCoy, - Yes, Nurse.
I have the diagnosis of the crewman
who attacked engineer Scott.
It was definitely due to the effects of interspace.
It's beginning to spread throughout the ship.
Are we any closer, Doctor?
No, except I'm positive
that it's a tharagen derivative that's the answer.
And it better be the next one.
Mr. Spock didn't believe me either,
did he, Doctor?
Well, nobody saw him but you, Uhura.
didn't really see him.
I don't think so.
Will I become like Chekov, Doctor?
We're working hard.
We'll find an antidote.
We're beginning to interphase.
I'm all right.
Scott to bridge.
Bridge. Spock here.
Are we slipping into interspace?
Negative. We are relatively stable at the moment.
Why do you ask?
I... don't believe it.
What is it, Mr. Scott?
Mr. Spock, I've just seen Captain Kirk.
He was standing there as plain as we are,
and then he Just disappeared.
Report to the bridge immediately.
Sounds like a horror story.
Any truth in it?
In critical moments,
men sometimes see exactly what they wish to see.
Are they seeing Jim because they've lost confidence in you?
I was merely stating a fact, Doctor.
It's getting critical.
There have been assaults on the lower decks.
Even Scotty's being affected.
If Scotty goes under,
we'll have no chance of getting out of here.
Please leave that to me, Dr. McCoy.
I realize that the crew are your prime concern.
You can best serve them in your laboratory.
Confine yourself to it
until a remedy has been found.
Must be this space is getting to me, too.
I know it's nothing you've done, Spock.
I-- I'm sorry.
I understand, Doctor.
I'm sure the captain would simply have said,
"Forget it, Bones."
Mr. Spock! Look!
Am I all right, Doctor?
Yes, Uhura, you're fine.
Then what I saw--
It was real.
Captain Kirk's alive?
We all saw him.
The captain's still alive.
Then your fears about that phaser were correct.
It blasted a hole right through that crazy space fabric.
Only heaven knows where it sent the Defiant.
Exactly. But the captain remained.
Only the overlap time changed.
The next interphase will occur...
Can you be ready?
That'll be about 20 minutes.
She'll be back together.
We'll only have 80% power built up.
It will have to do, Mr. Scott.
What have you got there?
Compliments of the house.
To your good health
and the health of the crew.
You found the antidote, Doctor.
Yes. I've ordered it orally or intravenously
for everyone aboard the ship.
I would like for you gentlemen
to drink it down.
Ensign Chekov was affected so early.
Has he responded to it?
He's his smiling self again.
I've discharged him from sick bay.
What is it?
It's a diluted tharagen derivative.
Tharagen -- a nerve gas used by the Klingons.
Aye! And deadly, too.
You're trying to kill us all?
It causes fatality only when used in pure form.
And in this derivative mixed with alcohol,
it merely deadens certain nerve inputs to the brain.
Well, any decent brand of Scotch will do that.
One good slug of this,
and you can hit a man with phaser stun,
and he'd never feel it or even know it.
Does it make a good mix with Scotch?
I'll let you know.
Well, drink it down, Spock.
It's the human thing to do.
That's a medical order...
Welcome back, Lieutenant.
Thank you, sir.
Your absence was keenly felt, Mr. Chekov.
Thank you, Mr. Spock.
Estimated time for completion of the Tholian web.
2 minutes, sir.
Are the ships computers programmed
for entry into interspace?
Yes, sir. The ship can drive into interspace at any time.
Spock to engineering.
Prepare for interphase in 15 seconds.
Aye, sir. Standing by.
Mr. Spock, they're closing the web.
Interphase in 10 seconds,
Stand by with full power.
- 4, 3-- - She's only up to 76%.
It will have to do.
Ready to transport on my order.
- I see him. - There he is!
It's the captain.
The tractor field is activating.
We're being pulled out of here.
Maintain position Mr. Sulu.
I can't, sir.
Bring ship's power up to full capability.
Where are we now, Mr. Spock?
Captain, we have destroyed the Tholians' web.
The ship's power has thrown us clear of it.
Compute the distance from the original location.
At once, sir.
Have we lost the captain?
We shall soon see, Lieutenant.
The ship has been thrown exactly 2.72 parsecs
distant from our previous position.
Good. Since the captain was locked into our transporter beam
when we were thrown clear,
he should've been drawn here with us.
Spock to transporter room.
The captain's oxygen supply is running out now.
Are you standing by
with a hypo of triox-compound for him?
I'm ready, Mr. Spock.
Prepare to transport on the captain's coordinates
on my order.
Ready, Mr. Spock.
Mr. Spock, it's him!
It's the captain!
I see him, Ensign.
I see him.
Welcome home, Jim.
I had a whole universe to myself
after the Defiant was thrown out.
There was absolutely no one else in it.
I must say I prefer a crowded universe much better.
How did you two get along without me?
Oh, we managed.
Mr. Spock gave the orders, and I found the answers.
No problems between you?
None worth reporting, Captain.
Only such minor disturbances,
as are inevitable when humans are involved.
Which humans, Mr. Spock?
He means when humans become involved with Vulcans, Jim.
Well, I hope my last orders
were helpful in solving any problems
that you don't feel worth reporting.
What orders are you referring to, Jim?
My last orders.
The last orders that I left for both of you.
The last taped orders.
Oh, those orders.
Well, there wasn't time.
We never listened to them.
No. You see, the crisis was upon us,
and then passed so quickly, Captain, that we--
Well, I hope we won't have similar opportunities
to test those orders...
which you never heard.
Ahead warp factor 2, Mr. Sulu.
Warp factor 2, sir.
