On the planet Pyris VII, two beings known
as Korob and Sylvia have been sent on a mission of conquest by their
home world. Using a matter transmuter, they assume human form to welcome
the U.S.S. Enterprise landing party.
When one member of the initial landing party returns to the ship dead,
Kirk, Spock and McCoy beam down to find Scotty and Sulu transformed
into mindless zombies. Sylvia and Korob appear as witch and warlock
and use scare tactics to keep the officers from investigating the planet
and their motives. Kirk, Spock and McCoy are taken prisoner and shown
examples of Korob and Sylvia's "powers," which includes heating
a small model of the U.S.S. Enterprise over a flame and having
the heat transfer to the orbiting ship.
Sylvia takes an interest in Kirk and decides to abandon her original
mission in order to learn about human feelings and experiences. When
she finds out the captain is merely using her to gain an advantage,
she becomes furious and retaliates.
Korob ultimately helps the crew to escape, but Sylvia turns into a giant
black cat and crushes him. Kirk then uses Korob's wand transmuter to
destroy Sylvia's source of power — her amulet — before smashing the
wand. Their powers gone, the aliens revert to their true form — fragile
blue creatures who quickly die in the planet's atmosphere. With their
demise, Scotty and Sulu return to normal and the landing party beams
back to the U.S.S. Enterprise.
