Black and white movie about a bunch of American prisoners of war held in Nazi Germany. It is one of the first movies to have an antihero. William Holden plays a prisoner who is always finding ways to get stuff from his fellow prisoners (definitely not likable). But when it becomes clear that there is an informer in the barracks and Holden's character takes the blame, he uses his street smarts to first figure out who the informer is and then what to do about it.
