Jaws (1975)

When, during the height of beach season, the town of Amity Island in Massachusetts is terrorized by attacks from a great white shark -- Martin Brody, the new chief of police must solve the problem. As the Mayor tries to avoid a panic which would deprive the town of its crucial tourist season, warnings to swimmers are avoided and more victims float to the surface.

Brody eventually enlists the help of a young oceanographer and a sea-wary fisherman to hunt down and destroy the great white menace that has turned the Amity Island shore into a feeding ground.
