The peaceful fishing community of California's Full Moon Bay is undergoing rapid change, as the greedy and unscrupulous real-estate magnate, Hamilton Lux, turns the seaside town into a tourist trap. Little by little, as a deadly toxin mutates the indigenous population of aggressive bull-sharks into unstoppable man-eating machines, the local fishermen, Daniel Wilder, and his wife, Brooke, along with the marine biologist, Dr Amy Zuckerman, must stop the violent sharks' feeding frenzy, before they evolve into something horrible. But, is there an escape from the blood-thirsty shark swarm?
