The Enterprise encounters the SS Botany Bay. She has been in space for centuries, carrying seventy two men and women in suspended animation. Kirk and Spock realize these people are dangerous refugees from Earth's last great war. The result of selective breeding and genetic engineering, these men and women possess superior power and skill... and superior ambition that drives their plans for the modern era. They awaken the group's leader, Khan Noonien Singh, but he quickly takes over the Enterprise and plans to lead a new war of conquest in the 23rd century.
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.
