When a young woman is killed by a shark while skinny-dipping near the New England tourist town of Amity Island, police chief Martin Brody wants to close the beaches, but mayor Larry Vaughn overrules him, fearing that the loss of tourist revenue will cripple the town. Ichthyologist Matt Hooper and grizzled ship captain Quint offer to help Brody capture the killer beast, and the trio engage in an epic battle of man vs. nature.
