Amity has not suffered a shark attack in years, but the fears of widow Ellen Brody (Lorraine Gary) resurface when her younger son is suddenly killed.
Believing the entire family is somehow threatened, she flies to the Bahamas to warn her marine biologist son, Michael (Lance Guest), of the danger. Meanwhile, also heading for the warmer waters is something big, hungry and out for revenge . . .
As Roger Ebert observed, what shark wouldn’t want revenge on the humans who killed it? They were still flogging a dead carcharodon carcharias as late as 1987.
The big rubber shark gets to attack an aircraft, but that’s far from being the only silly thing about this preposterous fourth entry in the series.
Michael Caine makes the most of the summer weather in the Bahamas and delivers a cheerfully irrelevant cameo. But Lorraine Gary, the only link – apart from the shark – with the fine original, is annoyingly neurotic, while the plot – this time with the shark getting personal – is laughably inept.
Judith Barsi, who played Thea Brody, died in 1988 at the age of 10 in a murder-suicide carried out by her father.
