In San Fernando, California, two gravediggers are filling the grave of a deceased woman, the young wife of an old man (played by Bela Lugosi). Suddenly they hear a strange noise and decide to leave the cemetery. As they turn to leave, the resurrected corpse of the old man's wife (played by Vampira) attacks and kills them. Meanwhile, in the skies nearby, a pilot named Jeff Trent (played by Gregory Walcott) and his co-pilot Danny encounter a flying saucer.
