The next morning Chief Martin Brody and his wife, Ellen, wake up in their charming oceanfront house. They banter playfully about doing the chores. Totes adorbs.
He gets a phone call and has to go check something out. Ellen says to be careful, but he's like, "In this town? Gimme a break."
He drives his cool Amity Police Department truck to the beach and meets his deputy and the boy who was too drunk to go skinny-dipping. His hair still looks ridiculous.
They discover what's left of Chrissie's body getting eaten by crabs, which grosses everybody out.
Brody returns to the police station to type up a report on Chrissie's death. He types in SHARK ATTACK as the probable cause of death.
Everybody keeps bugging him with trivial problems—illegal parking, kids karate-chopping fences, etc. Fill out the form, folks! Sheesh! He's trying to get everyone out of the water and close the beaches so nobody else gets eaten.
Mayor Larry Vaughn hears that Brody's trying to close the beaches and chases him down with a group of his cronies.
Vaughn tells Brody that it couldn't have been a shark that killed Chrissie, so he shouldn't close the beaches or say anything about a shark.
The town's livelihood depends on Amity's ability to attract summer vacationers, after all. Wouldn't want to have a panic on our hands on the 4th of July, would we?
