What happens
Professor Landry, a young archaeologist hoping to win a university post and marry Marsha, hires a guide named Pedro to find a lost city in Central America. Pedro's late grandfather once glimpsed a dead city beyond a cliff and spoke of a black door. Landry flies a helicopter over the mountains until they find an old volcano with a ruined temple and a carved black disc in its plaza. The episode is from the Suspense series, first broadcast on November 19, 1961, and starring Robert Redick, with Ralph Camargo.

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.
