The Colditz Story is a 1955 British prisoner of war film starring John Mills and Eric Portman and directed by Guy Hamilton. It is based on the 1952 memoir written by Pat Reid, a British army officer who was imprisoned in Oflag IV-C, Colditz Castle, in Germany during the Second World War and who was the Escape Officer for British POWs within the castle.

Plot

During World War II, the Germans transform Colditz Castle into a high-security prisoner-of-war camp called Oflag IV-C. Its purpose is to restrain those Allied prisoners who have attempted to escape from other Oflags. Colditz houses first Polish, then British, Dutch and French prisoners. Among the British are Pat Reid and Senior British Officer Colonel Richmond. Richmond is warned by the Kommandant that "escaping is verboten" but Richmond has no intention of heeding this advice. All the prisoners are wary of Priem, the chief security officer, who is efficient and tenacious.
