At the penultimate moment of the war against Nazi Germany, with victory near at hand for the allied forces, we learn that Hitler has one more trick up his sleeve he uses occult techniques to raise the dead. The war rages with the land overrun by zombies, until Hitlers defeat by a group of volunteers. This should have ended everything, but we find that corpses are still walking the Earth.
