What happens
Captain Bradford, Jerry, Tex and Mrs. Gregory land on a strange island in the South Seas, searching for Mrs. Gregory's long-lost daughter. They find themselves held in place by an unseen magnetic force and are met by a calm, precise man who calls himself G-47. He leads them through the island of Euclidea, a colony that measures time in seconds and names its people after scientists. Inside a small copper-doored room, Mrs. Gregory meets a young girl called Cleostra, who has no memory of her life before the island.
A hidden island in the South Seas called Euclidea, lit by a yellow half-light and governed by magnetic force and scientific order.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
