JAWS 2:The small island resort town of Amity is trying to bounce back from the financial problems it had after becoming known as the site of shark attacks four years ago. Mayor Larry Vaughn is welcoming developer Len Peterson and his new resort to Amity. Two scuba divers are exploring the area where the Orca sank after police chief Martin Brody killed a huge shark four years ago. A shark shows up and kills the two divers, but not before one of the divers takes a close-up picture of the shark's eye, and sometime later, while a mother is driving a boat that's pulling her water-skiing teenage daughter, the shark kills the daughter and causes the mother to accidentally blow up the boat, then a killer whale is found on the shore with a huge bite on it. After Brody sees this, he knows there's another huge great white shark in Amity's waters, but Vaughn and Peterson explain these attacks away as non-shark accidents...JAWS 3:Michael Brody and Sean Brody, the sons of former Amity police chief Martin Brody, work at Florida's Sea World, a seaside park run by Calvin Bouchard. Sean befriends Kelly Ann Bukowski, and Michael's girlfriend Kathryn Morgan is Sea World's head scientist who always works with Sea World's dolphins Cindy and Sandy. In its man-made lagoon, about 40 feet under the water, Sea World opens the Undersea Kingdom, a new set of underwater glass tunnels that have their own control room, and Calvin's friend Philip FitzRoyce is there to do some filming. When Sea World diver Shelby Overman vanishes, everyone is worried. Michael and Kathryn head into the water, where they find a baby great white shark and decide to bring it to Sea World to put it on display, but at Sea World, the baby shark dies. When Overman's body is found, Michael vomits when he sees it. Kathryn looks at the body and knows that the baby shark could not have been the shark that killed Overman... JAWS REVENGE:Ellen Brody still lives in the island resort town of Amity, and her sons Sean and Michael don't work at Sea World anymore, and some time ago, Ellen's husband Martin Brody died of a heart attack that happened because he was afraid of sharks. Sean is now a deputy in Amity. One night, during the Christmas season, Sean is called to untangle a log from a buoy, and when Sean goes to the buoy, he's killed by a great white shark. After hearing about this, Michael, who is studying to be a marine biologist, visits Amity with his wife Carla and his 5-year-old daughter Thea. Wanting to get away from Amity and spend Christmas with Michael, Carla, and Thea, Ellen goes with them to their house in the Bahamas on an airplane whose pilot is Hoagie Newcombe, and Hoagie starts falling for Ellen. Michael's friend Jake, who is also studying to be a marine biologist, lives next door to Michael. Sometime later...
