staying cloaked.
After that, we're visible,
and dead in the water.
We won't have enough
to break out of earth's gravity,
let alone get home.
I can't believe
we'll be stopped by this.
There's no way of
recrystallizing dilithium?
Sorry, sir.
We can't even do that
in the 23rd century.
Admiral, there may be
a 20th-century possibility.
Explain.
If memory serves,
there was a dubious flirtation
with nuclear fission reactors
resulting in toxic side effects.
By the beginning
of the fusion era,
these reactors
had been replaced,
but we may be able
to find some.
But you said they were toxic.
We could construct
a device to collect
their high-energy
photons safely.
These photons could
then be injected
into the dilithium chamber
causing crystalline
restructure,
theoretically.
Where would we find
these reactors,
theoretically?
Nuclear power was widely 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.
We'll divide into teams.
Commanders Uhura
and Chekov, the uranium.
Dr. McCoy, you, Mr. Scott,
and Commander Sulu
will convert us a whale tank...
Oh, joy.
while Spock and I
attempt to trace these
whale songs to their source.
I'll have bearing
and distance, sir.
I want everybody to be careful.
This is terra incognita.
Many of their customs
will doubtless surprise us.
It's a foregone conclusion
none of them have seen
an extraterrestrial before.
This is an extremely primitive
and paranoid culture.
Chekov will issue a phaser
and a communicator
to each team.
We'll maintain radio silence
except in emergencies.
Those in uniform
remove your rank insignia.
Any questions?
All right.
Let's do our job
and get out of here.
Our world's waiting
for us to save it...
if we can.
Commence landing procedure.
Aye, sir.
You two are fighting again?
I thought you made up last night.
Why are you always fighting?
I like the way she fights.
I said, "If you think
I'm spending $60
for a toaster oven, you're crazy. "
Then what did she say?
Well, she-
What the hell was that?
Did you see that?
No, and neither did you,
so shut up.
Bearing to the whales?
283 degrees,
15.2 kilometers.
Everybody remember
where we parked.
Watch where you're going,
you dumb-ass!
Well, double
dumb-ass on you!
It's a miracle these people
got out of the 20th century.
They're still using money.
We've got to find some.
Spock. Everybody else stay here.
The rest of you, break up.
You look like a cadet review.
Yes. 18th-centuryAmerican.
Quite valuable.
Are you sure you want
to part with them?
How much will you give me?
Weren't those a birthday present
from Dr. McCoy?
They will be again.
That's the beauty of it.
How much?
They'd be worth more
if the lenses were intact.
I'll give you $100.
Is that a lot?
All right.
That's all there is,
so don't splurge.
All set?
Good luck.
Mr. Spock, here we are.
Thanks to your restored memory
and a bit of good luck,
we're walking
the streets of San Francisco
Looking for a couple
of humpback whales.
What's the solution?
Simple logic will suffice.
I'll begin by making use
of this map.
I have the distance and bearing
provided by Commander Uhura.
If we juxtapose
our coordinates,
we should be able
to find our destination
which lies at
283.7 degrees-
I think we'll find them
at the Cetacean Institute
in Sausalito-
two humpback whales,
George and Gracie.
How do you know?
Simple logic.
What does it mean,
"exact change"?
How do we plan
to convert this tank?
Ordinarily, I'd do it
with transparent aluminum.
You're a number
of years too early.
I know. We've got to find
the 20th-century equivalent.
But where?
Did you find it?
Yes. Under
U.S. government.
Now we need directions.
Sir, can you direct me
to the naval base
in Alameda?
It's where they keep
the nuclear vessels.
Nu-cle-ar...
vessels.
Excuse us.
Excuse me, we
