In the brooding medieval castle of Colditz

Located near the German border with Czechoslovakia, Allied prisoners of the Second World War devised every method of escape from twisting tunnels to an improvised glider flight from the dreaded Nazi-held castle. In 1942, only Sergeant Tony Irving and five Allied accomplices discovered how to march through the narrow door and escape. Acting with faith and patriotism, the Allied soldiers break out and run toward Switzerland.
