It all started the previous summer. Marc, his wife, and their two beautiful teenage daughters agreed to spend a week at the Meier's extravagant summer home on the Mediterranean. Joined by Ralph and his striking wife Judith, her mother, and film director Stanley Forbes and his much younger girlfriend, the large group settles in for days of sunshine, wine tasting, and trips to the beach. But when a violent incident disrupts the idyll, darker motivations are revealed, and suddenly no one can be trusted. As the ultimate holiday soon turns into a nightmare, the circumstances surrounding Ralph's later death begin to reveal the disturbing reality behind that summer's tragedy.
