Watch Star Trek: The Original Series Season 4 show Online Streaming Iconic series STAR TREK -- a show thats launched a thousand spin-offs, movies, books, games, action figures, and conventions -- chronicles the adventures of the U.S.S. Enterprise, a spaceship representing the United Federation of Planets in the 23rd century. The ship is on a mission to explore the space frontier, but the show itself isnt as much about space as it is about the people on the Enterprise. Among them are brash, emotional Capt. Kirk (William Shatner); logical Vulcan Spock (Leonard Nimoy); and hot-headed Dr. Leonard "Bones" McCoy (DeForest Kelley). Creator Gene Roddenberry also made a point of including crew members of various ethnic backgrounds, including Japanese Lt. Hikaru Sulu (George Takei), Russian Ensign Pavel Chekov (Walter Koenig), and Scottish Lt. Cmdr. Montgomery "Scotty" Scott (James Doohan), and African-American Lt. Nyota Uhura (Nichelle Nichols).
