The Portuguese coast west of Lisbon: A man's body is washed ashore. Detective Pinto finds a video camera in a nearby parked car, and the tape inside shows a young woman who is apparently unaware of being filmed. Pinto later finds the woman and an interrogation begins, but her explanations only give rise to more confusion. What did Hans, the dead archeologist, have planned for her? What role did the Portuguese man play before he died in an accident?
