Nature's perfect killing machine has now become man's greatest weapon... For many years the US Navy has been training Dolphins for mine sweeping. But what if a more deadly maritime creature could be trained as an attack weapon? One such creature exists today; a prehistoric creature that has outlived the dinosaur; a creature that is the perfect killing machine... the shark. Bio-engineer Jim Castle has developed the 'warrior shark'. Bred from replicated DNA samples these sharks are bigger than a Killer Whale and 10 times as deadly! However when Castle's creations break out of the facility and head for the Florida coastline a battle is set in motion between an army of monster sharks and those who created them.
