美国画家保罗·法雷尔(Kerwin Mathews 饰)来到法国南部一个名叫圣纪龙德的偏僻所在。在当地一家小旅店内,他邂逅了青春靓丽的女招待安妮特·贝纳特(Liliane Brousse 饰)及其性感妖艳的继母伊芙(Nadia Gray 饰)。保罗为安妮特的美丽所吸引,但他很快落入伊芙精心编织的爱情陷阱中,两人干柴烈火,难舍难分。此后不久,伊芙请求保罗救出她的丈夫乔治(Donald Houston 饰)。原来就在4年前,安妮特被农夫詹尼罗(Arnold Diamond 饰)所强暴。愤怒的乔治用极其残忍的手法教训了这个强奸犯,而他也因此被关进看守所。伊芙许诺救出乔治后就和保罗私奔,保罗信以为真,铤而走险。却不曾想将死神带到自己的身边……Kerwin Matthews, playing a dissolute drifter down on his luck, Jeff Farrell, is stranded in a cheap bar in France where he falls for Annette, the proprietor's pretty stepdaughter, played by Liliane Brousse. Annette's stepmother Eve, played by Nadia Gray, gradually shifts the young man's attentions to herself, rather than her stepdaughter, and together Eve and Jeff concoct a plot to help free Eve's estranged husband from the institution in which he's been confined as a homicidal maniac these past four years after committing the so-called "Acetylene Murder", when he killed with a blowtorch the man who raped Annette. The idea is that Georges, the husband, will leave the country, but, unknown to Jeff, it's not Georges who escapes but Henri, the guard who has become Eve's lover . . .
