The 74th episode of Gene Roddenberry’s science fiction series Star Trek airs on NBC. This episode sees Spock use a version of a Vulcan mind-meld on Kirk, urging him to “forget”; the later movies will reveal that this memory manipulation technique has an opposite number: “remember”… 
Stardate 5843.7: On an urgent mission to procure the antidote to a serious plague which threatens the entire crew of the Enterprise, Kirk, Spock and McCoy beam down to Holberg 917-G to contact Flint in hopes of finding either the remedy or the raw material from which to extract it. Flint’s lovely female android, Rayna, begins to create a rivalry between Kirk, for whom she begins to feel true love, and Flint, who created Rayna to provide him with companionship. Spock discovers that Flint may be an immortal being who has influenced Earth’s history in the past, and McCoy finds that Flint is slowly dying. But Kirk may not resolve his argument with Flint in time to help Spock and McCoy save the crew of the Enterprise.
