Four years after the traumatic episodes at Amity Island that was terrorized by a 25-foot-long great white shark devouring beachgoers until it was destroyed, Amity Island is at peace and opened a hotel at the Holiday Inn. Days after the opening, beachgoers start to disappear, along with a beached, half-eaten killer whale. Brody becomes concerned about these incidents and fears that another Great White Shark is on the loose.
