Amity Island is a tourist resort with a large number of tourists coming here to swim. However, the appearance of the great white shark changed everything. The accident started with a couple who went swimming in the sea. The woman unfortunately became the first victim, and her fragmented body was horrible to look at. Local officials were unwilling to close the site for investigation. They were afraid of affecting tourism revenue, so they invited biologist Brown (Richard Dreyfuss). Brown concluded that this was an unusually huge white shark. His warning did not attract enough attention from the authorities, and then someone died, and the situation became more serious. A local skilled fisherman, a policeman and Brown, a total of three people, were determined to kill the great white shark. The dangerous fight began. Who is the final winner? What price will be paid to win this battle?
