An offshore drilling accident releases a giant primordial shark. When the shark flies and walks on land threatening to turn a bikini contest into a bloodbath, marine biologist Kat Carmichael arrives to destroy the shark and save beach-goers. Her efforts are stymied by corporate bad guy Roger Wade and his flunky Stewart who are only interested in their own agenda of money, money, money. With time running out for beach loving humans, Carmichael recruits heroic skipper Chuck and fearless disc jockey Dynamite Stevens to help her blast the blood thirsty shark back to a watery grave.
