Captain's log:
Our position: Orbiting Psi 2000,
an ancient world, now a frozen wasteland
about to rip apart in its death throes.
Our mission: Pick up a scientific party below,
observe the disintegration of the planet.
- Check out the life-support systems. - Right, sir.
All life systems were off, sir.
Someone strangled this woman.
- The other four are back there. - Dead?
- Right, sir. - Engineer at his post?
He's frozen there like he didn't care.
The rest?
Well...
Better look for yourself, Mr. Spock.
One man was taking a shower fully clothed.
Be certain we expose ourselves to nothing.
Spock here. Do you read, Enterprise?
- Kirk. Affirmative. - All station personnel are dead.
- What caused it? - Unknown, captain.
It's like nothing we've dealt with before.
Space, the final frontier.
These are the voyages of the starship 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.
Captain's log, stardate 1704.2:
The science party we were to have picked up has been found dead.
Life-support systems had been turned off,
station personnel frozen to death, conditions highly unusual.
Meanwhile, we remain in orbit to complete our mission:
Close scientific measurement of the breakup of this planet.
- Did you receive my signal, Mr. Scott? - Yes, sir.
Decontaminate.
- Captain here. - Spock and Tormolen aboard, sir.
We're holding them in the chamber for decontamination.
Better have Medicine look them over too.
Tell Mr. Spock I'll meet him there in ten minutes.
Kirk out.
You're fine, Joe. Up and out of there.
Mr. Spock.
Your pulse is 242.
Your blood pressure is practically nonexistent,
assuming you call that green stuff in your veins blood.
The readings are perfectly normal for me, doctor. Thank you.
And as for my anatomy being different from yours, I am delighted.
- Captain. - How are they?
- They're fine, Jim. - Terrible, captain.
It was terrible. They were just sitting like they didn't care.
Whatever was happening, they didn't care.
- I keep wondering... - You keep wondering
if man was meant to be out here.
You keep wondering, and you keep signing on.
Any guesses, Mr. Spock? Any idea what happened down there?
I wish I could say, captain. Circumstances were quite bizarre.
However, our record tapes may show us something.
Six dead. Six people dead.
- You better get some rest. - Yes, sir.
Set up those tapes, Mr. Spock. We'll see if the answers are there.
- The lab status report, doctor. - Oh, thank you, Christine.
Next tape, please.
- Spectroanalysis tape, sir. - Thank you.
Almost as though they were irrational, drugged.
An engineer there, apparently oblivious to everything, a woman strangled,
a crewman with a phaser pistol in his hand.
He'd used the computer room as if it were an amusement gallery.
And a fully clothed man frozen to death in a shower.
If the image wasn't so ugly, it'd be laughable.
- Not even a theory, gentlemen? - Definitely not drugs or intoxication.
The bioanalysis on the tapes prove that conclusively.
Could be some form of space madness we've never heard of.
But it would have to be caused by something.
Our spectro readings showed no contamination,
no unusual elements present.
Or at least none your tricorders could register.
Instruments register only those things they're designed to register.
Space still contains infinite unknowns.
Earth science needs the closest possible measurement
of the breakup of this planet.
To do this, we need the Enterprise in a critically tight orbit. Question:
Could what happened down there to those people
create any unusual danger to this vessel and crew?
We will need top efficiency, captain. It'll be a tricky orbit.
When a planet begins to go, there may be drastic changes
in gravity, mass, magnetic field.
The purpose of a briefing, gentlemen, is to get me answers
based on your abilities and experience.
In a critical orbit, there's no time for surprise.
Unless you people on the bridge start taking showers with your clothes on,
my engines can pull us out of anything.
We'll be warping out of orbit within a half-second of getting your command.
Bridge to captain.
Kirk here.
Scanners report sudden four-degree shift
in planet magnetic field.
A change in mass also, sir.
It's beginning. Unusually rapid shifts.
On our way, lieutenant.
I'll hold you to that half-second, Scotty.
Foil. It's a rapier, a thin sword.
All right. So, what do you do with it?
What do you mean, "What do you do with it?"
Self-defense, mayhem, shish kebab?
- You practice. - For what?
Hi, Joey.
Last week it was botany he was trying to get me interested in.
I was supposed to be collecting leaves, plant specimens...
Your attitude is all wrong.
Fencing tones the muscle, sharpens the eye, improves the posture.
You tell him, Joey. Explain to him.
Hey, Joey.
- You feeling all right? - Get off me.
You don't rank me, and you don't have pointed ears, so just get off my neck.
- What's with him? - Nothing.
Attention: Engine room on standby alert.
All duty personnel to the bridge. Acknowledge.
You sure you're all right now, Joe? We've gotta leave.
We're all a bunch of hypocrites.
Stick our noses into something that we've got no business.
- What are we doing here anyway? - Take it easy, Joe.
Bring pain and trouble with us.
Leave men and women stuck out on freezing planets until they die.
What are we doing out here in space? Good?
What good?
We're polluting it, destroying it.
We've got no business being out here, no business.
- Take it easy now, would you? - Now calm down.
If a man was supposed to fly, he'd have wings.
If he was supposed to be out in space, he wouldn't need air to breathe.
Wouldn't need life-support systems to keep him from freezing to death.
- Hey, Joey, put the knife down, huh? - You're all steamed up, Joe.
We don't belong here.
It's not ours, not ours.
Destroying and watching...
We don't belong.
I don't belong.
Six people died down there.
Why do I deserve to live?
- What are you doing, Joe? - Hey, Joey, put the knife down.
- Don't be a fool. - Let go, let go!
- Let me have the knife! - Please let go!
Joey, don't be a fool.
Joey...
Joey, give me the knife.
Emergency! Rec room, area 39! We need medics!
Captain's log, supplemental:
Our orbit, tightening. Our need for efficiency, critical.
But unknown to us,
a totally new and unusual disease has been brought aboard.
- Relative gravity increasing, sir. - Compensate, Mr. Riley.
- Yes, sir. - Magnetic field continuing to shift, sir.
Planet continuing to shrink in mass.
- Mr. Spock? - All scanning stations manned,
all recorders functioning, captain.
Orbit steady now, sir.
Obviously, this planet is condensing more rapidly than expected.
A valuable study.
We may be seeing Earth's distant future.
Before its sun went dark, this planet was remarkably similar to yours.
- Helm answering nicely, captain. - Good.
Communications status, captain.
- Tormolen's record? - Psychiatric file, personality quotients.
- Was he trying to kill himself? - It's doubtful he meant to.
He was confused, self-tortured.
Doesn't sound like the man I know.
His capacity for self-doubt has always been rather high.
What puzzles me is what brought it to the surface with so much force.
His breathing rate is dropping, doctor.
Compensate with the respirator.
Stand by to close.
Closing.
- What is it? - Relative gravity increase, sir.
Like the planet reached out and yanked at us.
Compensate.
Orbit steady now, sir.
Maybe a little nervous, I guess.
This shouldn't be happening.
This man should be getting stronger.
You sure the respirator is functioning properly?
Yes, doctor.
Well, why is this man dying?
Hypo.
He's dead, doctor.
The wounds were not that severe.
This is McCoy. Captain Kirk to Sickbay.
Uhura, monitor communications.
- Tell McCoy I'll be there when I can. - Yes, sir.
Planet breakup is imminent, captain. Shrinking in size at an increasing rate.
As the planet continues to shrink in size,
its surface moves away from us.
Forcing us to spiral down to maintain the same distance from it.
Exactly. We must be prepared to respond instantly
to any sudden change.
- Engine room from bridge. - Scott here, captain.
Tie into the helm, Scotty. If we should call for power, we'll want it fast.
No problem, sir. You'll have it.
Rate of compaction seems constant.
Then I'll go see what the good doctor wants.
Keep me informed of any change, Mr. Spock.
Acknowledged.
Don't know if it's this planet or what happened with Joe...
- I'm sweating like a bridegroom. - Yeah. Me too.
Hey, why don't you come down to the gym with me, Kevin, my lad?
Now? Why not?
- A light workout will take the edge off. - Hey, Sulu, what about--?
Hey, Sulu, don't be a fool.
Come.
Intestinal damage wasn't that severe.
I got to him in plenty of time. That man should still be alive.
Only reason he died, Jim, is he didn't wanna live. He gave up.
- That's a supposition, not a fact. - Well, that may be. It may be.
I've lost patients before, but not like that.
Not Joe's kind. That kind of man doesn't give up.
Coincidence?
Maybe.
You mean that Joe was down on the planet's surface,
and you're gonna ask me if it's connected?
That's exactly what I was gonna ask.
Jim, he was decontaminated, he's been medically checked,
we've run every test we know for everything we know.
- That's not good enough. - We're doing everything possible.
Bones, I want the impossible checked out too.
Why isn't Mr. Sulu at this station?
Magnetic pull compensated for. Orbit steady.
- Take over here, Rand. - Yes, sir.
You haven't answered my question. Where is Mr. Sulu?
Have no fear, O'Riley's here.
- And one Irishman is worth 10,000-- - You're relieved, Mr. Riley.
Lieutenant Uhura, take over this station.
- Yes, sir. - Now that's what I like.
Let the women work too. Universal suffrage.
- Report to Sickbay, Mr. Riley. - Sickbay?
Exactly where I was heading, sir.
Security, Mr. Riley is headed for Sickbay. See to it he arrives.
Captain Kirk to the bridge.
Where's Joe?
- Well-- - He died, didn't he?
Yes.
You know something...
...you have such lovely eyes.
Pretty lady.
I know he was a friend of yours. This must be a terrible shock.
You know what Joe's mistake was?
He wasn't born an Irishman.
Richelieu, beware!
Stand.
No farther.
No escape for you.
You either leave this bois bloodied
or with my blood on your swords.
Cowards!
- Lieutenant Brent, relieve Miss Uhura. - Yes, sir.
What were their symptoms?
Nonviolent at this stage. Slightly disoriented.
Riley seemed rather pleased with himself, as if he were--
Irrational.
Or drugged.
- Precisely. - Security, Lieutenant Uhura.
- Yes, sir. - Sulu and Riley, locate and confine.
I want every crewman who comes in contact with them medically checked.
Sir, level two, corridor three reports a disturbance.
Mr. Sulu chasing crewmen...
...with a sword.
- Put security on it. - Fascinating. A pattern is developing.
First Tormolen,
hidden personality traits being forced to the surface.
Then Riley, who fancies himself a descendant of Irish kings.
And now Sulu, who is at heart a swashbuckler out of your 18th century.
- Present condition of Psi 2000? - Gravity pull increasing.
We've shifted two percent and should stabilize.
- Helmsman, stabilize position. - Helm is not answering to control.
- Warp us out of here. - No response from engines, sir.
Impulse power then. Blast us out of this orbit.
Impulse engines also dead, sir.
Engine room, we need power!
Mr. Scott, acknowledge!
Our controls are dead.
Take her.
Richelieu, at last.
Sulu, put that--
- Put that thing away! - For honor, queen and France.
Sulu!
Ah.
Sulu, give me that.
- Sulu! - I'll protect you, fair maiden.
Sorry, neither.
Foul Richelieu!
I'd like you to teach me that sometime.
Take D'Artagnan here to Sickbay.
Scotty, we need power.
Engine room, acknowledge!
You rang, sir?
Who's this?
This is Captain Kevin Thomas Riley of the starship Enterprise.
- And who is this? - This is Captain Kirk.
Get out of the engine room. Where's Mr. Scott?
I've relieved Mr. Scott of his duties.
And now, attention, cooks. This is your captain speaking.
I would like double portions of ice cream for the entire crew.
- Clear that too, will you? - Yes, sir.
And now,
your captain will render an ancient Irish favorite.
I'll take you home again
Captain. At our present rate of descent,
we have less than 20 minutes before we enter planet atmosphere.
And burn up. I know, Mr. Spock!
Captain's log, stardate 1704.4:
Ship out of control, spiraling down towards planet Psi 2000.
We have 19 minutes of life left without engine power or helm control.
- How did Riley get in there? - He said you wanted us on the bridge.
He's cut off helm and power.
He shut the door and locked off the mechanism.
- Can't you get to the auxiliary? - He's hooked everything
through the main panel.
Get up to my office and pull the plans for this bulkhead.
The only way to get that door open
is to cut through these wall circuits here.
The roses all have left your cheeks
I've watched them fade away and die
Status reports, all sections.
A fight in the aft wardroom.
Security reports incidents among the crewmen are increasing.
Go to alert Baker Two. Seal off main sections.
All decks, alert system B2.
Repeat, go to alert condition Baker Two.
Seal off all main sections. Stand by.
Sealed off, if we can minimize the spread of whatever this is.
- Continue the alert, lieutenant. - I can't, sir.
He's cut off the alert channels.
Lieutenant Uhura, you've interrupted my song.
I'm sorry, but there'll be no ice cream for you tonight.
- Cut him off. - I can't, sir. There's no way to do it.
Attention, crew. This is Captain Riley.
There will be a formal dance in the bowling alley at 1900 hours tonight.
- Stand by. - No way, captain.
He controls the main power panels.
He can override any channel from down there.
Seventeen minutes left, sir.
Sickbay to bridge.
- Can you tie me into the Sickbay? - I'm getting you, Jim.
Look, can you keep this beast level?
I've got Sulu tranquilized, and we're running tests on him.
So far, there's nothing unusual in his bloodstream.
Body functions seem normal.
Riley's the immediate problem, doctor.
Is there any way, anything you can do to snap him out of it?
Negative, until I can get a little further on these tests.
This is Captain Riley.
Crew, I have some additional orders.
In the future, all female crew members will wear their hair
loosely about their shoulders.
And use restraint in putting on your makeup, women.
Women should not look made up.
And now, crew, I will render "Kathleen"...
...one more time!
Please, not again.
I'll take you home again, Kathleen
I've watched them fade away and die
I've set the jumpers up there. Stand by till I give you a signal.
And tears bedim your loving eyes
Oh, I'll take you home, Kathleen
Engineering to bridge. Try your helm.
You'll have enough power to keep her stabilized.
Here, let's have a look at that.
Sixteen minutes left, captain. We've stabilized, but spiraling down.
Emergency signal, captain.
Both decks four and five, fights and disorders.
- Get me Sickbay. - I have no intercom for Sickbay.
- He keeps switching channels on me. - See if you can help Dr. McCoy.
Better check Scotty first, move him faster.
He's gotta get through that bulkhead.
Crewman, report to the lab.
I'll take you home again, Janeen
What's going on?
I'm trying to get to the bridge, and this crewman won't let me by.
- Crewman, stand aside. - Oh, well, yes, sir.
I'll take you home again, Janeen
Spock!
- Message from the captain. - Tell him I'm doing my best.
- If I cut through the wrong circuits-- - We have 14 minutes left.
Even if we were under full-scale attack, I couldn't move any faster,
not and maintain a safety factor.
At the rate you're proceeding, calculations show
that you'll take a minute and a half more than we have left.
You can't afford a safety factor.
Biopsy Lab.
Biopsy, where's my report?
Biopsy, come in.
Harrison, where's my report?
- I'm going to the lab. - Sir?
- Yes? - The tranquilizer's wearing off.
Oh, good. I'll need him conscious now.
Continue to examine him on circuits K1 and 3.
Of course, doctor.
Get him out of here.
I would've gotten here sooner, but Crewman Moody--
- Take the helm. - Sir?
- Take the helm! - Yes, sir.
And now one more time!
At least try cutting him off!
Sir, if I could cut him off, don't you think I'd--?
I'll take you home again, Kathleen
Yes, sir. I'll keep trying.
Sorry.
Across the ocean wild and wide
- Scotty? - Engine room.
We've got 12 minutes left.
It'll take at least two or three of them to get the engines up to power.
Then we'll make it, sir, if all goes right.
Call me when you've cut through. I'll wanna be there. Kirk out.
Nurse?
Where is Dr. McCoy?
He's gone to the lab.
Lab?
Lab, respond please. Spock here.
Lab?
- Mr. Spock. - What is it, nurse?
Mr. Spock...
...the men from Vulcan treat their women strangely.
At least, people say that.
But you're part human too.
I know you don't...
You couldn't...
...hurt me.
Would you?
I'm in love with you, Mr. Spock.
You...
...the human Mr. Spock...
...the Vulcan Mr. Spock.
- Nurse, you shouldn't-- - Christine. Please.
I see things, how honest you are.
I know how you feel.
You hide it, but you do have feeling.
Oh, how we must hurt you, torture you.
I'm in control of my emotions.
The others believe that. I don't.
I love you.
I don't know why, but I love you. I do love you.
Just as you are.
Oh, I love you.
I'm sorry.
Captain is en route Engineering.
Can you take the bridge? Acknowledge.
I am sorry.
Christine.
Bridge to Sickbay. Is Mr. Spock there?
Mr. Spock, would you please acknowledge?
I will take you home, Kathleen
Almost ready, sir.
To where your heart will feel no pain
When the fields are fresh and green
I'll take you to your home
- Ready, sir. - Follow me through.
Put your phasers on stun.
Don't fire unless he's armed. Go.
I'll take--
No dance tonight.
Get him out of here.
I'm in control of my emotions.
Control of my...
I am an officer.
Officer.
My duty...
My duty is to...
Too late.
I am sorry.
Two.
Four.
Six.
Six times...
Six and 30...
Scotty, we haven't got much time left.
Bridge to captain.
Kirk here.
Entering planet's outer atmosphere.
- Captain. - What is it?
He's turned the engines off.
Completely cold. It'll take 30 minutes to regenerate them.
Ship's outer skin is beginning to heat, captain.
Orbit plot shows we have about eight minutes left.
- Scotty. - I can't change the laws of physics.
I've got to have 30 minutes.
Captain's log, supplemental:
The Enterprise, spiraling down, out of control.
Ship's outer skin heating rapidly
due to friction with planet atmosphere.
- Maybe 22, 23 minutes-- - Scotty, we've got six.
Captain, you can't mix matter and antimatter cold.
We'd go up in the biggest explosion since--
We can balance our engines into a controlled implosion.
That's only a theory. It's never been done.
Bridge, have you found Mr. Spock yet?
If you wanted to chance odds of 10,000-1 maybe,
assuming we had a row of computers working weeks on the right formula.
Mr. Spock is not on the bridge.
I was on the bridge.
Hey, doc, what am I doing here?
McCoy to Bio. We've isolated it. Start preparing serum.
What, doctor?
It's water.
On this planet, water's changed to a complex chain of molecules.
- What's that, doctor? - That's how we missed it.
It passed through perspiration.
Once in the bloodstream, it acts like alcohol.
Depresses the centers of judgment, self-control.
Now get someone to the lab! Tell them the serum works
and start preparing more!
Doc, will you let me out of here? I'm all right.
Release him.
Engineers, man your stations.
Engine rooms, report. Cycling station, report.
This will be an emergency restart of engines.
- Where have you been? I've been-- - My mother...
I could never tell her I loved her.
We've got four minutes, maybe five.
An Earth woman, living on a planet where love,
- emotion is bad taste. - We've got to risk a full-power start.
The engines were shut off. No time to regenerate them. Do you hear me?
- We've got to risk a full-power start. - I respected my father, our customs.
I was ashamed of my Earth blood.
Jim...
When I feel friendship for you, I'm ashamed.
You've got to hear me!
We need a formula! We've got to risk implosion!
It's never been done.
Understand, Jim...
...I've spent a whole lifetime learning to hide my feelings.
We've got to risk implosion. It's our only chance.
It's never been done.
Don't tell me that again, science officer! It's a theory. It's possible.
We may go up into the biggest ball of fire since the last sun exploded,
but we've gotta take that 1 in 10,000 chance.
Bridge to captain. Engineer asked did you find--
Yes, I found Mr. Spock! I'm talking to Mr. Spock!
- Do you understand? - Yes, sir.
- Three and a half minutes left, captain. - I've got it.
The disease.
Love.
You're better off without it, and I'm better off without mine.
This vessel...
I give.
She takes.
She won't permit me my life. I've got to live hers.
Jim...
I have a beautiful yeoman.
Have you noticed her, Mr. Spock?
You're allowed to notice her.
The captain's not permitted...
Jim...
There is an intermix formula.
Now I know why...
...it's called "she."
It's never been tested.
It's a theoretical relationship between time and antimatter.
A flesh woman to touch,
to hold.
A beach to walk on.
A few days, no braid on my shoulder.
Captain.
Scotty.
Help.
Stand by to intermix.
I'll call the formula in from the bridge.
Entering upper stratosphere.
Skin temperature now 2170 degrees.
I've got to hang on.
Tell them, clear the corridors, the turbo lift.
Hurry.
Never lose you.
Never.
Bridge.
Engine room.
We're set.
Hyperbolic course.
Direction, sir?
Direction...
It doesn't matter. The way we came.
Course laid in, sir.
Fuel temperature?
Level.
No beach to walk on.
Sir?
Raise antimatter 840 degrees.
That'll take four minutes.
We haven't the time. We'll have to risk it.
Bridge, we're ready.
Engage.
- Are you all right, Jim? - You?
We've found a cure. We're over that part of it.
Obviously, we were successful.
- The engines imploded. - Captain.
My velocity gauge is off the scale.
Engine power went off the scale as well.
We're now traveling faster than is possible for normal space.
Check elapsed time, Mr. Sulu.
My chronometer is running...
...backwards, sir.
Time warp.
We're going backward in time.
Helm, begin reversing power.
Slowly.
Helm answering, sir.
Power reversing.
We're back to normal time, captain.
Engines ahead.
Warp one.
Warp one, sir.
- Mr. Spock? - Yes, sir.
The time warp...
- ...what did it do to us? - We've regressed in time 71 hours.
It is now three days ago, captain.
We have three days to live over again.
Not those last three days.
This does open some intriguing prospects, captain.
Since the formula worked,
we can go back in time to any planet, any era.
We may risk it someday, Mr. Spock.
Resume course to our next destination, Mr. Sulu.
Course laid in, sir.
Steady as she goes.
Captain's log:
Our position: Orbiting Psi 2000,
an ancient world, now a frozen wasteland
about to rip apart in its death throes.
Our mission: Pick up a scientific party below,
observe the disintegration of the planet.
Space, the final frontier.
These are the voyages of the starship 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.
Captain's log, stardate 1704.2:
The science party we were to have picked up has been found dead.
Life-support systems had been turned off,
station personnel frozen to death, conditions highly unusual.
Meanwhile, we remain in orbit to complete our mission:

- Warp us out of here. - No response from engines, sir.
Impulse power then. Blast us out of this orbit.
Impulse engines also dead, sir.
Captain's log, stardate 1704.4:
Ship out of control, spiraling down towards planet Psi 2000.
Sickbay to bridge.
- Can you tie me into the Sickbay? - I'm getting you, Jim.
Sixteen minutes left, captain. We've stabilized, but spiraling down.
Emergency signal, captain.
Both decks four and five, fights and disorders.
- Get me Sickbay. - I have no intercom for Sickbay.
- He keeps switching channels on me. - See if you can help Dr. McCoy.
Better check Scotty first, move him faster.
He's gotta get through that bulkhead.
Get him out of here.
I would've gotten here sooner, but Crewman Moody--
- Take the helm. - Sir?
- Take the helm! - Yes, sir.
And now one more time!
At least try cutting him off!
Sir, if I could cut him off, don't you think I'd--?
I'll take you home again, Kathleen
Yes, sir. I'll keep trying.
Sorry.
Across the ocean wild and wide
- Scotty? - Engine room.
We've got 12 minutes left.
It'll take at least two or three of them to get the engines up to power.
