The Germans always seem to be forewarned about escapes and in the most recent attempt the two men, Manfredi and Johnson, walked straight into a trap and were killed. For some in Barracks 4, especially the loud-mouthed Duke, the leaker is obvious: J.J. Sefton a wheeler-dealer who doesn't hesitate to trade with the guards and who has acquired goods and privileges that no other prisoner seems to have. Sefton denies giving the Germans any information and makes it quite clear that he has no intention of ever trying to escape. He plans to to ride out the war in what little comfort he can arrange, but it doesn't extend to spying for the Germans. As tensions mount and a mob mentality takes root, it becomes...

Frederick Manion (Ben Gazzara), a lieutenant in the army, is arrested for the murder of a bartender, Barney Quill. He claims, in his defense, that the victim had raped and beaten up his wife Laura (Lee Remick). Although Laura supports her husband's story, the police surgeon can find no evidence that she has been raped. Manion is defended by Paul Biegler (James Stewart), a rather humble small-town lawyer. During the course of interviews, Biegler discovers that Manion is violently possessive and jealous, and also that his wife has a reputation for giving her favors to other men. Biegler realizes that the prosecution will try to make the court believe that Laura was the lover of the bartender and than Manion killed him and beat her up when he discovered them together. Manion pleads "not guilty" and Biegler, who knows that his case is weak, sets his assistants to try to find a witness who will save Manion.
