The Brody family, not led by the widow Ellen Brody (Lorraine Gary), continues to experience shark attacks, starting with when Ellen's younger son, Sean. While mourning the loss, Ellen visits her other son, Michael (Lance Guest), in the Bahamas, where she meets the rascally Hoagie Newcombe (Michael Caine). Meanwhile, the same shark that got her boy appears off the coast of the island, and Ellen has to take it down or never escape the shark's wrath. Mario Van Peebles also appears in this Joseph Sargent film so bad that it killed off the Jaws franchise once and for all.
