Wendy remembers nothing about the farmhouse fire that killed her father. She doesn't remember her father or even her own name. Her guardian, Jared Parker, has learned that she is not human, that she is not of this world at all. But he doesn't tell Wendy, even when he sees her falling in love with police officer Aaron McCormick. When Butch Cruickshank, one of the young punks who set fire to Wendy's home, guesses her secret, he brings ruthless millionaire UFO hunter Earl Vaughn to town. Vaughn has offered $10,000 to anyone who finds an alien artifact—and an android is certainly worthy of the prize. Vaughn becomes convinced that Wendy is not human, and he hatches a scheme to create an army of androids to help him conquer the world.
