The first showing on network television of this action adventure starring Michael Caine, Lorraine Gary

Years have passed since the tranquillity of the tiny seaport of Amity was shattered by a giant shark with a taste for human flesh. Ellen Brody has rebuilt her life, and is proud of her son Sean, who is now Amity's deputy sheriff - the job held by his late father. But out in the dark waters something big is lurking, out for revenge.
