but Mayor Larry Vaughn persuades him to reconsider, fearing that the town's summer economy will be ruined. The coroner tentatively concurs with the mayor's theory that Chrissie was killed in a boating accident, and Brody reluctantly accepts their conclusion until the shark kills a young boy, Alex Kintner, in front of a crowded beach. A bounty is placed on the shark, causing an amateur shark-hunting frenzy, and eccentric and roughened local professional shark fisherman Quint offers his services for $10,000.

At nightfall, Quint and Hooper drunkenly exchange stories about their assorted scars, and Quint reveals that he survived the attack on the . The shark returns unexpectedly, ramming the boat's hull, and disabling the power. The men work through the night, repairing the engine. In the morning, Brody attempts to call the Coast Guard, but Quint, who has become obsessed with killing
