 The Stooges are incompetent and dim-witted repairmen fixing the doorbell of a large house, which, unbeknownst to them, is the secret headquarters of a group of Nazi agents, headed by the ruthless Hans (Vernon Dent).They manage to disembowel the wiring of the walls and destroy most of the house as they work.Moe and Larry then subdue Hans and his Japanese cohort, assume their wardrobes (emulating Adolf Hitler and Hideki Tojo) and ultimately sink their submarine by remote control.
