Logan's Run 40th Anniversary Blogging: "Carousel" (January 16, 1978)
In the City of Domes, our amnesiac Logan undergoes a "truth" scan and immediately picks up his old life as a swinging single. In particular, there's a young denizen named "Sheila" (played by Melody Anderson, Flash Gordon's Dale Arden) who would like to pick up precisely where they left off a year ago.
Logan, who was already figuring out, has his memory restored. He and his friends escape the city, and continue their search for Sanctuary…
Interestingly, at one point during "Carousel" Logan declares that Sanctuary (his longtime goal...) is just a place "invented by runners to encourage other runners."
