The Portuguese coast west of Lisbon: A man's body is washed ashore.

Police detective Pinto finds a video camera in a nearby parked car, on tape a young woman apparently unaware of being filmed. Pinto later finds the young woman and an interrogation begins, but her explanations only give rise to more confusion.

What did Hans, the dead archeologist, plan for her? What role did the young Portuguese man play before he died in an accident? And what happened to the other women Hans filmed as well?
Pinto thinks in the end that he has discovered the structure behind all this, but did everything really happen as he imagines it? Or does truth lie only in the eye of the beholder?
