Matt Farrell (Ashley) is plucked from the sea while skin-diving and taken to the foreboding fortress of Dr. Gordon. He is to become part of the doctor's diabolical experiment to create a race of super people.

This twisted and maniacal doctor's experiments have so far only created terrifying, hideous creatures. Freed by the doctor's own daughter, they turn the island into a bloodbath of terror!
