What happens
Clark Kent and Jimmy Olsen recover two boxes of dynamite hidden by the Inca Indians in a mountain tunnel, after Jimmy warns that the Indians had tried to get rid of him before. Kent confronts the Inca guards, who believe he has returned from the dead, and the two escape with the explosives. Back with the American engineer John Craig, they face the problem of placing the dynamite so that the underground river can be brought above ground without flooding the Inca city. Kent and Craig discuss the difficulty, and the group settles down to rest for the night. This is an episode of The Adventures of Superman, a radio series.

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.
