A man wakes naked and cold on a deserted beach. The only sign of life for miles is an empty BMW. Inside it he finds clothes that fit perfectly, shoes for his tattered feet, a Rolex and a driving licence in the name of Daniel Hayes, resident of Malibu, California. None of them is familiar. When the cops kick in the door of his dingy motel room with guns drawn, the man flees into the night. All he remembers is a woman's face, so he sets off for the only place where he might find her. Might that be the way back to himself? But that raises the most chilling question of all: what will he find when he gets there?
