In the film, the police chief of Amity Island, a summer resort town, tries to protect beachgoers from the predations of a huge great white shark by closing the beach, only to be overruled by the town council, who want the beaches to remain open to draw a profit from tourists. After several attacks, the police chief enlists the help of a marine biologist and a professional shark hunter to kill the shark.
