Lt. Commander Kelowitz
Voice of the Metrons
emergency call summons the Enterprise to Cestus III but, by the time they
arrive, the colony has already been destroyed. Shortly after their arrival
both the landing party and the ship find themselves under attack from
an unidentified race. Kirk, on the planet's surface, gives orders for
the Enterprise to leave the area while he defends the ground position.
Finding a powerful mortar-like weapon in the colony's arsenal the landing
party manages to fight off their attackers after which a mysterious, alien
craft leaves orbit. They come across a single survivor from the original
attack who tells them that the onslaught was unprovoked and that it was
merely a means of attracting the Enterprise into a trap. Kirk believes
that this could be a 'test run' for an alien invasion and, beaming back
to the starship on its return, starts to pursue the alien vessel which
is heading into an uncharted region.
After a long pursuit both ships are suddenly instantly stopped in space
and a voice, announcing itself as belonging to the Metrons, tells them
that it plans to resolve the situation. The Metrons transport both Kirk
and the captain of the alien ship, a lizard-like creature called a Gorn,
down to the surface of a planet in an uncharted system and tell them that
there are sufficient materials there with which to construct weapons.
They will be fighting for their lives as the Metrons announce their intention
of destroying the loser's ship. The Gorn is much physically stronger than
Kirk and he has to use his wits and greater speed to survive. The crew
of the Enterprise watches the trial by combat on their viewscreens as
Kirk tries desperately to find the promised weapon materials. He digs
deep into his memory for ideas and eventually gathers enough items to
make a crude type of gunpowder.
Finding a large hollow tube he constructs a primitive cannon, using a
large raw diamond as the projectile. The Gorn is lured into position and
Kirk fires, severely disabling the alien creature. With the Gorn at his
mercy he calls to the Metrons and tells them that he refuses to take the
life of the alien.
At that point one of the Metrons appears and tells him that they had not
expected him to display the advanced trait of mercy and that they had
reconsidered their plan, which was to destroy the winner, not the loser
as they had stated. The Enterprise is spared and the Metrons leave Kirk
with the hope that, sometime in the distant future, their two civilisations
may become friends.
