What happens
Superman, the strange visitor from another world, rescues Clark Kent, Lois Lane, Jimmy Olsen and their companions from the sea after their submarine is sunk by a tanker. Aboard the drifting tanker, they find no crew, a table set for dinner, and the captain dead in his chair. The captain's log describes a frightening figure called the old man of the seaweed. Clark, Jimmy and the others try to make sense of the strange events aboard the ship. The series is The Adventures of Superman, first broadcast on December 28, 1942.
A tanker in the mid-Atlantic Ocean, aboard which the ship is deserted except for the dead captain.
Characters: Superman, Clark Kent, Lois Lane, Jimmy Olsen, Nick, Captain
Listen for: The captain's log entry describing the old man of the seaweed, and the discovery of the seaweed-covered figure in the pilot house.
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.
