Jaws is set in the fictional town of Amity, a small, seaside resort located on the south shore of
Long Island, halfway between
Bridgehampton and
East Hampton. One night, after making love with a man on the beach, a young woman named Christine "Chrissy" Watkins
skinny dips alone in the ocean where she is attacked and killed by a massive
great white shark. The next morning, her partially eaten remains are found washed up on the beach and the coroner concludes she was the victim of a shark attack. Amity Police Chief Martin Brody then orders the beaches closed, but he is overruled by mayor Larry Vaughan and the town's
selectmen who fear damage to summer tourism, Amity's main source of commerce. With the collusion of Harry Meadows, editor of the local newspaper, news of the attack is kept quiet. A few days later, the shark kills a young boy and an elderly man within half an hour of each other. Ben Gardner, a local fisherman, is hired to catch the shark but he disappears at sea. Brody and his deputy, Leonard Hendricks, discover Gardner's deserted boat anchored off-shore, covered with large bite holes, one of which has a large shark tooth stuck in it. The boy's mother and Gardner's widow angrily blame the deaths on Brody for not closing the beaches after they learn of the earlier attack on Chrissy Watkins. Wracked by guilt, Brody orders the beaches closed and has Meadows investigate Vaughan's business affairs to find out why he is so determined to keep them open. Meadows soon discovers that the mayor is heavily in debt to the
Mafia who have a great deal of money invested in Amity real estate and are pressuring Vaughan to keep the beaches open in order to protect their investments; if Amity's market value should fall, Vaughan stands to lose everything, including, possibly, his life. Meadows also recruits Matt Hooper, a young
ichthyologist from the
Woods Hole Oceanographic Institution for help on dealing with the shark. When shown the tooth found on Gardner's boat, Hooper determines it to be the tooth of an unusually large great white shark. Meanwhile, Brody's wife, Ellen, is suffering from depression and lamenting the loss of her youth and the affluent lifestyle she had prior to marrying Brody and having children. Coincidentally, when Ellen was a teenager, she dated Hooper's older brother a few years before meeting Brody. Ellen becomes fixated on Hooper as a link to the past she desperately longs for. After Hooper attends a dinner party at the Brody's, Ellen, intent on recapturing her juvenescence and
joie de vivre, decides to seduce him. The following morning, she telephones Hooper at his hotel and invites him to meet her for lunch at a restaurant several miles away from Amity. At the restaurant, the two have several drinks and begin flirting with each other; following a sexually charged conversation, they go to a motel. Unable to reach Hooper nor Ellen by phone that afternoon, Brody begins to suspect they have had a liaison and he becomes obsessed and tormented by the thought. After a week with no further attacks or sightings of the shark, Mayor Vaughan convinces Brody to reopen the beaches. By this time, news of the shark attacks have spread; tourists and the media flock to Amity for a glimpse of the killer shark. Brody sets up patrols along the beaches to watch for the fish. The shark returns and a teenage boy narrowly escapes another attack near the shore. Brody again closes the beaches and convinces the town's selectmen to hire Quint, an eccentric, crusty professional fisherman, to locate and kill the shark. Brody and Hooper set out with Quint on his boat,
Orca, and the tension between the three men soon escalates. Brody and Quint both regard Hooper as a conceited rich kid; Hooper is angry over Quint's methods when he disembowels a
blue shark and uses an illegally caught unborn baby dolphin as bait. Brody's suspicions about Hooper and Ellen increase, as he discovers more circumstantial evidence that points to a possible tryst between them. Their first day at sea is unproductive, but the three come in contact with the shark by the end of the second day. Upon seeing the fish for the first time and estimating the shark to be at least in length and weighing in at roughly , Hooper is visibly excited and in awe at the size of it. Larry Vaughan visits the Brody house and informs Ellen that he and his wife are leaving Amity. Vaughan speculates on the life he might have led had he married Ellen. After he leaves, Ellen reflects on her life and she realizes the mistake she made missing the life she had before marrying Brody. When Brody returns home a short time later, Ellen kisses him passionately. On the third day, Hooper wants to bring along a
shark-proof cage, in an attempt to kill the fish with a
bang stick. Initially, Quint refuses to bring the cage on board, considering it a suicidal idea, but he relents after Hooper pays him $100. Brody tells Quint he will not be paid if he brings the cage on board which angers Hooper and a heated argument between Brody and Hooper ensues. Unable to control his temper, Brody physically attacks Hooper and strangles him for several seconds. After several unsuccessful attempts by Quint to harpoon the shark, Hooper goes underwater in the shark cage. The shark attacks the cage, something Hooper did not expect. After destroying the cage, the shark kills and eats Hooper. Brody is horrified and is now convinced the shark can't be killed. He tells Quint that after Hooper's death the town may no longer pay him, but Quint is now determined to kill the shark regardless of the money. Quint and Brody return to sea the next day. After the shark attacks the
Orca and Quint harpoons it several more times, the fish leaps out of the water and onto the stern of the boat, smashing the transom.
Orca begins to sink and Quint plunges another harpoon into the shark's belly. As the fish settles back into the water, Quint's foot becomes entangled in the rope attached to the harpoon and he is pulled underwater and drowns. Brody, now staying afloat on a seat cushion, watches the shark slowly swim towards him; he closes his eyes and prepares for death. Just as the shark reaches Brody, it succumbs to its wounds and dies before it can attack. Slowly, the shark begins to sink. The lone survivor of the ordeal, Brody watches the dead shark spiral downward and disappear into the depths, dragging Quint's body, still entangled in the harpoon rope, with it; he then begins to paddle back to shore on his makeshift float. ==Development==
