Mr President.
The probe is heading for us,
damaging everything in its path.
The Klingons have lost two vessels.
Two starships and three smaller
vessels have been neutralised.
- Neutralised? How?
- We don't know.
Get me the Yorktown.
Emergency channel 0130. Code red.
Since contact with the alien probe, all
attempts to regain power have failed.
It's using forms of energy
we do not understand.
- Can you protect us?
- We're launching everything.
We are trying to deploy
a makeshift solar sail
to generate enough power
to keep us alive.
- Systems report.
- Communications systems all ready.
Communications officer,
as ready as she'll ever be.
Guidance has a functional interface
with the Federation memory bank.
Weapons systems
and cloaking device are operational.
I'm impressed.
We're in an enemy vessel.
I did not wish to be shot down.
Engine room, report.
We're ready. The dilithium sequencer
is now a little less primitive.
And I've replaced
the Klingon food packs.
- They were giving me a sour stomach.
- Is that what it was?
Prepare for departure. Everybody
not going to Earth had better get off.
- Saavik... this is goodbye.
- Yes, Admiral.
Thank you.
Sir, I have not had the opportunity
to tell you about your son.
David died most bravely.
He saved Spock.
He saved us all.
I thought you should know.
Good day, Capt. Spock.
May your journey be free of incident.
Live long and prosper, Lieutenant.
Permission to come aboard, Admiral.
Jim, Spock. Don't you remember?
It would not be proper to refer to you
as Jim while you're in command.
Also, I must apologise for my attire.
I seem to have misplaced my uniform.
Station.
- Is this a good idea?
- What?
Him, back at his post
like nothing happened.
He's not exactly
working on all thrusters.
- lt'll come back to him.
- Are you sure?
That's what I thought.
Mr Sulu, take us home.
Thrusters functional.
One quarter impulse power.
Space dock, this is Starfleet.
Launch all vessels.
Space dock doors are inoperative.
All systems are non-functional.
Starfleet, this is space dock.
We have lost all internal power.
Estimating planet Earth,
1 .6 hours at present speed.
Continue on course.
Any sign of Federation escort?
No, sir,
and no Federation vessels on patrol.
That's odd.
Uhura, what's on the com channels?
Very active. Multi-phasic
transmissions. Almost a gibberish.
Let me see if I can sort it out.
Hi. Busy?
Uhura is busy. I am monitoring.
It sure is nice to have your Katra
back in your head, and not mine.
I may have carried your soul,
but I sure couldn't fill your shoes.
My shoes?
Forget it.
Perhaps we could cover
a little philosophical ground.
Life, death, life.
Things of that nature.
I've not yet reviewed
the philosophical disciplines.
Come on. You really have gone
where no man has gone before.
- Tell me what it felt like.
- We have no frame of reference.
- You're joking.
- A joke is a humorous story.
I have to die
to discuss your insights on death?
I'm receiving
a number of distress calls.
I don't doubt it.
Juneau, Alaska.
Clouds increasing to 95%.
Tokyo, total cloud coverage.
Leningrad has lost all electrical power.
Cloud coverage 100%.
Temperature decreasing rapidly.
- What is Earth's total cloud coverage?
- 78.6%.
Starfleet emergency. Red alert.
Switch to planetary power reserves.
Even with all planetary reserves
we cannot survive without the sun.
I'm well aware of that.
Ambassador Sarek, I'm afraid
you're trapped here with us.
There's no way
we can answer this probe.
It's difficult to answer when one
does not understand the question.
Perhaps you should transmit
a planetary distress signal...
..while we still have time.
- Admiral?
- What is it?
Overlapping distress calls
and a message from the Federation.
This is the President
of the United Federation of Planets.
Do not approach Earth.
The transmissions of an orbiting probe
are critically damaging this planet.
It
