A group of five teenagers decides to take a dinghy out to sea and gets lost during a storm. In luck, they spot an abandoned yacht in the middle of the ocean. Climbing aboard to seek shelter, they find out it is a deep sea research vessel. The marine lab studies on mutated fish after feeding on plankton contaminated by dumped radioactive waste. One of the specimens that has escaped kills the whole crew and preys on the unsuspecting teenagers.
