An Italian high school student becomes infatuated with a woman he sees outside his class window. Her fiancée is in jail for being involved in a radical movement, and she spends much time in court providing moral support. At first she resists the student's advances, but eventually begins an affair with him. Their situation is condemned by her family and his father, who is the woman's psychologist.

Molinat is assigned to the case of a man found with a bullet in his ear on the shore of a little Atlantic coast resort he knows well. Indeed, he used to live there before his wife disappeared at sea, never to be found again. As the ocean rejects a new corpse everyday, the mystery thickens and the list of potential suspects grows longer. This slows Molinat's progress as much as the cumbersome Leroyer, sent in to spy on him and hopefully impede his progress. The tension mounts and the ring involving the three young ladies in the grey mansion, the village idiot and the real estate agent starts spinning out of control.
