During the height of World War II, a German submarine torpedoes an Allied ship containing Nazi prisoners of war. A German prisoner, Richter (Roland Varno, the Return of the Vampire), escapes from the ship and disguises himself as a British soldier. But Sergeant Terry Hunter (Tom Neal, Detour, 1945) has his suspicions of Richter. So when Richter attempts to break a group of Nazi soldiers out of the local POW camp, it's up to Hunter and the townspeople to stop him.
