The answer is: A turgid melodrama. The question: What is Jeopardy? Barbara Stanwyck stars as a suburbanite on a Mexican vacation with her husband (Barry Sullivan) and son (Lee Aaker). The threesome runs afoul of escape convict Ralph Meeker.
Stanwyck's dilemma: Attempting to rescue her husband from drowning, while staving off the carnal demands of Meeker, who holds Stanwyck and her son at gunpoint. Jeopardy is on and off in only 69 minutes, but 64 of those minutes seem far longer.
Trivia note: When dramatized on Lux Radio Theater, Jeopardy costarred child actor Harry Shearer, later a comic regular on Saturday Night Live.
