Lieut. Klinger, a wounded Luftwaffe ace, is the only German who can ID the location of the Allied troops standing ready to invade Sicily. The Rat Patrol captures him and then Moffitt takes his place so that he can convince the Germans to watch in the wrong place for the upcoming attack. Troy, meanwhile, infiltrates the military hospital. Gestapo Major Bruder however suspects Moffitt and exposes him, but by the time he does, Moffitt manages to get Bruder killed in his place and escape.
