3.
- Steady as she goes.
Warp 4.
Warp 5.
Warp 6.
Warp 7.
- Warp 8.
- Heat shields at maximum.
Warp 9!
- 9.2, 9.3...
- We need breakaway speed.
9.5, 9.6, 9.7...
9.8...
Now!
I should never have left him.
Jim, where are we?
You're talking about
the end of everybody on Earth.
Mr Sulu...
Mr Sulu.
- Aye, sir.
- What is our condition?
- The breaking thrusters have fired.
- Picture, please.
Earth...
But when? Spock?
Judging by atmospheric pollution,
the latter half of the 20th century.
- Well done, Spock.
- We may be visible to them.
Quite right. Engage cloaking device.
- Crossing the terminator into night.
- The west coast of North America.
- I am receiving whale song.
- Put them on speakers.
This is strange.
The song is coming
directly from San Francisco.
From the city?
That doesn't make sense.
We have a serious problem.
It's these Klingon crystals.
The time travel drained them.
- They're decrystalising.
- Give me a round figure.
24 hours, staying cloaked. After that
we're visible and dead in the water.
We haven't the power to break out
of Earth's gravity or get home.
We can't stop now.
Can't we recrystalise the dilithium?
We can't even do that
in the 23rd century.
Admiral, there may be
a 20th century possibility.
I recall there was a dubious
flirtation with nuclear fission reactors.
They resulted in toxic side-effects
and were replaced in the fusion era.
But at this time,
we may be able to find some.
- But you said they were toxic.
- We collect only high-energy photons.
These photons would recrystalise
the dilithium structure... theoretically.
- Where would we find these reactors?
- They were used in naval vessels.
San Francisco. I was born there.
It doesn't look all that different.
- Set us down in Golden Gate Park.
- Aye, sir. Descending.
Uhura and Chekov
are assigned the uranium problem.
Dr McCoy, Mr Scott and Mr Sulu
will convert us a whale tank.
Oh, joy!
Capt. Spock and I will attempt
to trace these whale songs.
Be very careful,
this is terra incognita.
Many of their customs
will take us by surprise.
None of these people
have ever seen an extraterrestrial.
This is a primitive
and paranoid culture.
Take a phaser and a communicator.
Radio silence except in emergencies.
Remove your rank insignia.
Any questions? All right.
Let's do our job and get out of here.
Our own world is waiting for us.
- Commence landing procedure.
- Aye, sir.
Were you two fighting again?
I thought you made up.
- Why are you two always fighting?
- I like the way she fights.
I told her I wasn't spending $60
on a damn toaster oven.
- What did she say to that?
- Well...
What the hell was that?
- Did you see that?
- No, and neither did you.
- Bearing to the whales?
- 283 degrees, 15.2 kilometres.
Everybody remember where we parked.
Watch where you're going, dumb-ass!
Double dumb-ass on you!
- It's a miracle our race survived.
- They're still using money.
Spock. The rest of you stay here.
Break up,
you look like a cadet review.
18th century American.
Quite valuable.
- You do want to part with them?
- How much will you give me?
- Those were a gift from Dr McCoy.
- And they will be again.
- How much?
- The lenses aren't intact.
- I'll give you $100.
- Is that a lot?
That's all there is. Don't splurge.
All set? Good hunting.
Thanks to your restored memory,
and a little bit of good luck,
we're walking around San Francisco
looking for humpback whales.
- How will you solve this problem?
- Simple logic will suffice.
I will make use of this map.
I have the distance and bearing
from Uhura.
283.7 degrees...
We'll find what we're looking for
at the Cetacean Institute in Sausalito.
- How do you know this?
- Simple logic.
What does "exact change" mean?
How do we convert this tank?
- If I had transparent aluminium...
- You're years too early for that.
- Let's find their equivalent.
- But where?
- Did you find it?
- Yes, now we
