an enormous male human. Harry fires his pistol at the giant, but the gunfire has no effect. Harry flees, leaving Nancy behind. She is later discovered on the roof of her pool house in a delirious state and must be sedated by her family physician, Dr. Cushing (Roy Gordon). The doctor comments on scratches he finds on Nancy's neck, and theorizes that she was exposed to radiation. Egged on by his mistress Honey, Harry plans to inject Nancy with a lethal dose of her sedative, but when he sneaks up to her room, he discovers that she has grown to giant size. In a scene paralleling Nancy's first alien encounter, only an enormous hand is seen as Harry reacts in horror. Cushing and Dr. Von Loeb, a specialist brought in by Cushing, are at a loss on how to treat their giant patient. They keep her in a morphine-induced coma and restrain her with chains while waiting for the authorities to arrive. The sheriff and Jess (Ken Terrell), Nancy's faithful butler, track enormous footprints leading away from the estate to the alien sphere. Inside the sphere, they find Nancy's diamond necklace (containing the largest diamond in the world) and other large diamonds, each in a clear orb. They speculate that the jewels are being used as a power source for the alien ship. The huge human reappears, and the sheriff and Jess flee. Meanwhile, Nancy awakens and breaks free of her restraints. She tears off her mansion's roof and, clothed in a bikini-like arrangement of bed linens, heads to town to avenge herself on her unfaithful husband. Ripping the roof off the local bar, she spots Honey and drops a ceiling beam on her rival, killing her. Harry panics, grabs Deputy Charlie's pistol, and begins shooting, but she picks up Harry and walks away. The gunshots have no apparent effect on her. The sheriff fires a shotgun at her, which causes a nearby power line transformer to blow up, killing her. The doctors find Harry lying dead in her hand.
