Revenge of the Creature
The Creature (John Agar) is captured by a team of researchers and transported to a holding tank in a Florida marine park. Once imprisoned, the "Gill Man" becomes the subject of crude and cruel experiments conducted by his supposedly superior human captors. But the tormented Creature begins to emerge as a hauntingly beautiful alien and a female researcher (Lori Nelson) forms an uneasy emotional link with him. Soon they are both driven to break free of their respective "prisons".
