The long-suffering wife (Lorraine Gary) of Chief Brody decides she's had enough of Amity Island and hikes it to the Caribbean to join her son Michael (Lance Guest), her daughter-in-law and her grandchild. But that pesky shark (or is it the shark's mate?) follows her south and begins to wreak havoc in the azure seas of the Gulf Stream. Michael Caine co-stars in a role that owes something to the Quint character of the Spielberg original.
