This planet is ageing in surges.
- And Spock with it.
- lt seems they're joined together.
- They are.
How long?
Days. Maybe hours.
l'm sorry.
lt will be hardest on Spock.
Soon he will feel the burning
of his Vulcan blood.
- l don't understand.
- Pon Farr.
Vulcan males must endure it every
seventh year of their adult life.
Whoever they are,
they're getting closer.
- l'll go.
- No.
l'll do it. Give me your phaser.
Sir, Starfleet calling USS Grissom.
A warning about us.
- Response?
- Nothing. As before.
What's the Grissom up to?
Will she join us or fire on us?
Chekov, break silence. Send
Captain Esteban my compliments.
- How are we doing?
- How are we doing?
Funny you should put it
quite that way, Jim.
We are doing fine.
But l'd feel safer
giving him one of my kidneys
than what's scrambled in my brain.
No response from Grissom
on any channel.
Keep trying.
At regular intervals.
lt is called Pon Farr.
Pon Farr.
We are secured from Warp Speed.
Now entering Genesis Sector.
Proceed at impulse power.
- Vessel entering sector.
- Yes.
Federation Battle Cruiser.
Have they scanned us?
Not yet.
l'd swear there was
something there, sir.
What did you see?
For an instant, a scout class vessel.
Could be Grissom.
Patch in the hailing frequency.
Grissom, this is Enterprise calling.
Please come in.
Grissom, this is
Enterprise calling. Do you read?
Spock!
l've come a long way
for the power of Genesis.
And what do l find?
A weakling human,
a Vulcan boy and a woman.
My Lord, we are survivors
of a doomed expedition.
This planet will destroy itself soon.
The Genesis experiment is a failure.
A failure?
The most powerful destructive force
ever created.
You will tell me the secret
of the Genesis torpedo.
l have no knowledge.
Then l hope pain
is something you enjoy.
- l ordered no interruptions.
- But, sir...
- Federation Starship approaching.
- Bring me up.
Grissom, this is Enterprise calling.
Do you read?
Grissom, this is Enterprise
calling. Please come in.
Grissom, this is Enterprise.
Admiral Kirk calling Captain
Esteban or Lieutenant Saavik.
- Report status.
- We are cloaked.
Enemy closing on impulse power.
Range five thousand kellicams.
Good! This is just the turn of luck
l have been waiting for.
- Nothing on my scanner, sir.
- Short-range scan, Mr Chekov.
Put it on visual, Mr Sulu.
Range three thousand kellicams.
Steady. Continue on impulse power.
Range two thousand kellicams.
Stand by to transfer energy
to weapons.
At my command.
There! That distortion, see it?
Yes, sir. lt's getting larger
as we close in.
Firing range, sir.
- Opinion, Mr Sulu.
- l think it's an energy surge.
- Enough energy to hide a ship?
- A cloaking device.
Red Alert, Mr Scott.
One thousand kellicams and closing.
All power to the weapons systems.
Wait. Wait.
No shields?
lf my guess is right, they'll have to
de-cloak before they can fire.
May all your guesses be right.
- Klingon Bird of Prey. Arming.
- Fire, Mr Scott!
Good shooting, Mr Scott.
Precautionary, Mr Chekov, shields up.
Emergency power to the thrusters!
- Sir, the shield's non-responsive.
- Scotty?
The automation system's overloaded.
l didn't expect combat, you know.
Fire!
Emergency power.
Prepare to return fire.
Mr Scott, can you transfer power
to phaser banks?
l don't think so. They've
knocked out the automation centre.
- l've got no control over anything.
- Mr Sulu?
Nothing, sir.
So...we're a sitting duck.
Ready to fire emergency tube.
Why haven't they finished us?
They outgun me ten to one!
My Lord. The enemy commander
wishes a truce to confer.
Put them on screen.
This is Admiral James T. Kirk of
the Federation Starship Enterprise.
- The Genesis Commander himself.
- A violation of treaty...
..between the Federation
and the Klingon Empire,
..your presence here
is an act of war.
You have two minutes to surrender
your crew and your vessel...
- ..or we will destroy
