The 32nd episode of Gene Roddenberry’s science fiction series Star Trek premieres on NBC. Captain Kirk continues his winning streak of logically talking sentient computers into self-destructing, impressing Mr. Spock to no end. Scotty becomes the latest senior Enterprise officer to die in the line of duty, and by the end of the episode becomes the latest senior officer to miraculously come back to life. 
Stardate 3451.9: The Enterprise is attacked and boarded by the unusual space probe Nomad, which Spock identifies as the combined remains of an alien robot and an Earth exploration probe. Nomad’s purpose – a confused mix of aliens’ orders and instructions from Earth – is to seek out and sterilize all impurities, including imperfect beings like humans. The only thing preventing Nomad from obliterating the Enterprise and everyone on board is the similarity between the name of Nomad’s creator and Captain Kirk, and Kirk must try to play that role as best he can while figuring out how to get rid of Nomad.
