Résumé (jaquette) : Barry Nelson (The Shining) and Robert Lansing star in this futuristic horror thriller about technology's most terrifying mutation – the Island Calws.
The perpetual sun and cool breezes make this lush island a tropical paradise for vacationers. Marine biologists are also on the island, using it as a base for their studies on global food shortage. But something goes wrong in the lab-chemicals seep into the ocean and cause the unthinkable, the unfathomable to happen. A man-eating creature, beyond all parameters of science and evolution, emerges and terrorizes the island for human prey.
