When a large tiger shark is caught, Hooper disputes it being the same predator, confirming this after finding no human remains inside its stomach. While Hooper and Brody search the local waters at night, they discover local fisherman Ben Gardner's half-sunken boat. Hooper examines the vessel underwater and retrieves a sizable great white shark's tooth embedded in the hull. Startled by finding Gardner's partial remains, Hooper drops the tooth. Brody and Hooper inform Vaughn that a great white shark is responsible, but he discounts their claims and refuses to close the beaches, allowing only added safety precautions. On the Fourth of July weekend, the beaches are packed with tourists. Following a false alarm, the shark enters a nearby estuary and kills a boater. Brody coerces a devastated Vaughn to hire Quint.
