When the Enterprise arrives at Minara 2 to pick up a two-man science team because the planet's sun is going to supernova. Kirk, Spock, and McCoy find the station abandoned and discover the two men were transported away. Then the landing party is transported away to underground caverns where they find a mute alien woman from another planet in the system, and two native Vian scientists who put the landing party through a sadistic series of tortures.
Star Trek chronicles the 23rd century adventures of the U.S.S. Enterprise, one of twelve state-of-the-art starships representing Starfleet, the exploration branch of the United Federation of Planets, an alliance of alien races including Earth, Vulcan, Tellar, and Andor.
Captain James T. Kirk, the youngest starship captain in the Fleet, commands the Enterprise with a combination of brashness, authority, and imagination. The half-Vulcan/half-human Mr. Spock serves as his extremely logical and efficient First Officer and Science Officer. The ship's chief medical officer is Dr. Leonard McCoy, who has supreme medical authority on the ship and tends to the physical and mental needs of the Enterprise's crew of approximately 430.
Other ranking crew members include: Montgomery Scott, a man dedicated to his ship engines but not adverse to a bit of shore leave; Hikaru Sulu, helmsman and a man of many hobbies ranging from botany to fencing, Nyota Uhura, the extremely competent head of Communications, and Pavel Chekov, brash young navigator with a fierce pride in his native Russia.
