chunk: During a late-night beach party on Amity Island, a young woman goes swimming in the ocean. While treading water, she is violently pulled under. The next morning, her partial remains are found on shore. The medical examiner ruling the death a shark attack leads Police Chief Martin Brody to close the beaches. Mayor Larry Vaughn overrules him, fearing it will ruin the town's summer economy. The coroner now concurs with the mayor's theory that the girl was killed in a boating accident. Brody reluctantly accepts their conclusion until another fatal shark attack occurs shortly after. Amid an amateur shark-hunting frenzy, local professional shark hunter Quint offers his services for $10,000. Meanwhile, consulting oceanographer Matt Hooper examines the first victim's remains and concludes the death was from a shark attack.
