James Coburn guest stars as a ruthless German spy masquerading as an American G.I. in order to get into Battalion HQ to create havoc. When the jeep he is driving hits a land mine, Saunders and his squad bring him and two other German spies, one wounded, back to their Company HQ for first aid. Saunders slowly begins to suspect there is something wrong as Coburn's character makes slight mistakes while speaking and interacting with the other men.
