What happens
Clark Kent recounts his experiences on the planet Utopia, where he and Jimmy Olsen are held prisoner by Regent Saram. Saram's astrologer has miscalculated, and the planet begins to crack apart earlier than predicted. Saram plans to launch his warriors toward Earth at eleven o'clock and orders Kent, Olsen, Poco and Amphar to watch from the courtyard. Kent strains against the heavy gravity, trying to break free. The planet continues to crumble around the prisoners as the episode builds toward its climax. The Adventures of Superman, from 1947, presents this story in its twelfth part.

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.
