Jaws (1975)

It's a hot summer on Amity Island, a small community whose primary business is its beaches. When new Sheriff Martin Brody discovers the remains of a shark attack victim, his first inclination is to close the beaches to swimmers. It doesn't sit well with Mayor Larry Vaughn and several local business people. Brody backs down to his regret of that weekend. A predator kills a young boy. The dead boy's mother puts out a bounty on the shark, and Amity is soon swamped with amateur hunters and fishermen hoping to cash in on the reward. A local fisherman with much experience hunting sharks, Quint, offers to hunt down the creature for a hefty fee. Soon, Quint, Brody, and Matt Hooper from the Oceanographic Institute are hunting the Great White shark at sea. As Brody succinctly surmises after their first encounter with the creature, they will need a bigger boat.
