A series of science-fiction horror films about humanoid fishmen living on an uncharted Caribbean island.
After their prison ship sinks in the Caribbean, a group of prisoners and a doctor wash ashore on a seemingly deserted island. They soon discover a strange couple, who invite them to stay at their house. While the prisoners plan an escape, the doctor does some investigating, and soon finds out just what the pair are really doing, and why the prisoners keep disappearing mysteriously.
Two teenagers prowl a devastated landscape, polluted by radioactive waste in search for food. On their quest of survival, they meet Socrates, a man who takes them to an island that seems a far cry away from the urban misery they struggled in. But the two youngsters ignore that the island is ruled by a beautiful but ruthless queen whose slaves are the hideous fishmen.
