What happens
Clark Kent, Perry White and John Craig, who are trying to reach the lost engineers in the Andes, find the Inca dungeon empty after Lois Lane, Jimmy Olsen and the pilot Bronson have been taken from it. The Inca council has sentenced Lois, Jimmy and Bronson to death unless they reveal how the men escaped. Kent knocks out three Inca warriors and the three men strip them and put on their native costumes to move through the city. Meanwhile Lois and Jimmy wait in an anteroom as the moon climbs, and are then led toward the valley of the shadows. The episode is part ten of the Pan-American Highway storyline in The Adventures of Superman, first broadcast on 1941-12-05.
The Inca city high in the uncharted Andes mountains, including the Inca Palace, its dungeon, a council chamber, and a courtyard leading toward a shadowed hill.
Characters: Clark Kent, Lois Lane, Perry White, Jimmy Olsen, John Craig, Bronson, Nehru
Listen for: Kent's trick of knocking out the three warriors, the three men's disguise in native costume, and the moon reaching its crest as Lois and Jimmy are led away.
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.
