The Nazis, exasperated at the number of escapes from their prison camps by a relatively small number of Allied prisoners, relocates them to a high-security ‘escape-proof’ camp to sit out the remainder of the war. Undaunted, the prisoners plan one of the most ambitious escape attempts of World War II. Based on a true story.

At the end of World War II, a National Guard infantry company must set up artillery observation posts in a strategic area. Lt. Costa (Jack Palance) knows that Capt. Cooney (Eddie Albert) is in command only because of the “connections” he made stateside. Costa has serious doubts concerning Cooney’s ability to lead, and when Cooney sends Costa and his men out on a dangerous mission — and refuses to reenforce them — all hell breaks loose.
