A passenger cruise line is lost at sea, and the only two survivors, Sam and Claire, wash up on a deserted island. The shock of the incident causes Sam to lose his memories. To survive, he and Claire must work together as they explore the island, forage for food, and sustain some kind of shelter until they can be rescued.
