The Enterprise encounters a powerful energy force that has apparently killed all human life in a solar system with over one billion inhabitants. They identify the culprit as a small space probe that had its origins on Earth. Called Nomad, it merged with another and, as a result, took on a new mission to destroy all biological beings as being imperfect. It believes Captain Kirk to be its creator and, as such, has spared the Enterprise and its crew, at least temporarily. Written by

In conventions, Nichelle Nichols
frequently tells a story of getting into a dispute with director Marc Daniels
over the filming of this episode. As it had already been established that Uhura's first language was Swahili, Nichols believed that, after her mind was erased, Uhura would revert to her first language. However, as Nichols herself did not speak Swahili, Daniels wanted Uhura to just speak English. Nichols refused to, telling Daniels, "Nichelle Nichols doesn't speak Swahili, but Uhura does!" Gene Roddenberry
was eventually brought in to settle the dispute, and he sided with Nichols. A linguist specializing in Swahili was then brought in to write the few lines of Swahili that are spoken in the episode. See more
A wire suspending the Nomad probe is visible in numerous scenes (namely, at 23:30 when Nomad hovers over to Spock's computer to read up on human anatomy, and at 28:20 in the brig before Spock performs a mind-meld). See more
I am the Kirk, the creator?
You are the creator.
You're wrong! Jackson Roykirk, your creator, is dead. You have mistaken me for him. You are in error! You did not discovered your mistake; you have made two errors. You are flawed and imperfect, and you have not corrected by sterilization; you're made three errors!
