When a hot air balloon crashes on a remote and uncharted island, the four balloonists and their dog Melvin are captured by a pair of drunken old pirates who take them to the hilltop laboratory home of Dr. Frankenstein's modern-day descendant Sheila Frankenstein (Katherine Victor) who is carrying on the family tradition by turning shipwrecked sailors into pre-programmed bloodless, black-garbed zombies who must wear sunglasses to protect their weird white eyes from light.
