In occupied Germany in 1960, four somewhat drunk American soldiers leave Florida Bar, where "Town Without Pity" is playing on the jukebox, and head to a river in the nearby countryside. Meanwhile, sixteen-year-old local Fräulein Karin Steinhof (Christine Kaufmann) has a quarrel with her 19-year-old boyfriend, Frank Borgmann (Gerhart Lippert), on the banks of the same river. She swims back to her starting point, lights up a cigarette and strips out of her wet bikini when she is confronted by Sergeant Chuck Snyder (Frank Sutton) and gang-raped by him, Corporal Birdwell Scott (Richard Jaeckel), Private Joey Haines (Mal Sondock), and Corporal Jim Larkin (Robert Blake). (A blatant production error can be seen in the film during the rape scene when a body double substitutes for Kaufmann; the "victim" has short, fluffy dry hair in contrast to Kaufmann's long, straight, wet hair.) Borgmann hears her screams for help and swims across the river to help her, but he is knocked out by Snyder. After three of the men start to leave the scene, the guilt-ridden Larkin lingers behind; he covers Steinhof with his shirt before he finally flees with the other three men.
