Just as Amity Island begins to rebound from a spate of deadly shark attacks, a pair of missing divers and a boating accident lead police chief Martin Brody (Roy Scheider) to suspect the worst, but his warnings go ignored by the mayor (Murray Hamilton). Sure enough, another great white lurks in the local waters, this time with its sights set on a group of sailing teens -- including Brody's two sons. Jeannot Szwarc directs this blockbuster sequel.
