Rae Ingram (Nicole Kidman) is involved in a car crash which results in the death of her son. Her older husband, Royal Australian Navy officer John Ingram (Sam Neill), suggests that they help deal with their grief by heading out for a vacation alone on their yacht. In the middle of the Pacific, they encounter a drifting boat that seems to be taking on water. A man, Hughie Warriner (Billy Zane), rows over to the Ingrams' boat for help. He claims that his boat is sinking and that his companions have all died of food poisoning.
