On September 8th, 1966 an unknown science fiction series debuted with it's inaugural episode. The show was "Star Trek" later known as "Star Trek: The Original Series" and the episode was "The Man Trap".

Not the original pilot, the second pilot, or even the intended first episode, "The Man Trap" starts with The Enterprise arriving at planet M-113 to provide supplies and routine medical exams to Doctor Robert Crater and his wife, Nancy, whom Dr. Leonard McCoy was once romantically involved with. M-113 has been home to the Craters for five years, during which time they have conducted an archaeological survey of the planet's ruins. They are the only known inhabitants of the planet.

Kirk, McCoy, and crewman Darnell beam down to the planet and meet Dr. Crater and, apparently, Nancy Crater, but each of the landing party sees a different woman. McCoy, who says he is amazed at how little Nancy has changed since he last saw her, sees Nancy as he knew her 10 years ago. Darnell sees a completely different, younger blond woman who looks exactly like someone he met before. Kirk sees a woman similar to the woman McCoy sees, but more appropriately aged. At the end of the first scene, crewman Darnell is lured away by the seductive version of Nancy Crater that he sees. (source Memory Alpha)
