In January 1944, six British officers tunnelled out of Colditz, the German prison camp that was supposed to be escape proof. Three were captured after a few hours, while the remaining three stayed on the run. Two, Captain Ben Thomas and Pilot Officer Robert Beauchamp made it to safety, while the third, Lt. George Irby, was shot as he tried to cross the border. In January 1994, Thomas and Beauchamp are back in Colditz, this time at a Colditz Veteran's reunion. As the men discuss the war it becomes clear that Irby may not have died. Thomas and Beauchamp attempt to track down their comrade and discover that Irby was involved in something sinister, something far larger than merely trying to escape.
