What happens
Clark Kent and Captain Walters travel by dog team into the Arctic wastes, searching for the missing expedition of Professor Peters and Ray Martin. Their trail leads them through an icy valley where a strange figure appears in the clouds, seemingly warning them to turn back. They press on toward a flickering light and reach a hut. There they find signs that the missing men may have been there, and Kent discovers an important clue. This is an episode of The Adventures of Superman, first aired on May 29, 1940.

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.
