The iconic series "Star Trek" follows the crew of the starship USS Enterprise as it completes its missions in space in the 23rd century. Captain James T. Kirk -- along with half- human/half-Vulcan science officer Spock, ship Dr. "Bones" McCoy, Ensign Pavel Chekov, communications officer Lt. Nyota Uhura, helmsman Lt. Hikaru Sulu and chief engineer Lt. Cmdr. Montgomery "Scotty" Scott -- confront strange alien races, friendly and hostile alike, as they explore unknown worlds.

The Enterprise discovers a remote world bearing an unlikely resemblance to 1920s Chicago; guest Vic Tayback.

The disappearance of a Vulcan ship leads a weary Enterprise crew into battle with a huge space organism.

A power struggle between the Federation and the Klingon Empire ensnares a primitive society Kirk once visited.
