What happens
Superman, disguised as reporter Clark Kent, and young Jimmy Olsen search the Andes Mountains for Perry White and Lois Lane, who flew there to find nine missing American engineers. After Jimmy falls from an airplane, Clark rescues him and they reach Tupangato, where they find evidence that the lost Inca people still exist. Clark and Jimmy disguise themselves in Inca costumes and dye their skin, hoping to pass among the native warriors who surround them. The episode ends with the Incas closing in on them as they try the disguise and an Inca flute. This episode is part six of the serial The Adventures of Superman, which aired on November 26, 1941.

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.
