Sicilia, late '60s. Two men are killed during a hunting party. The hurried inquiry indicates that it was a killing made for 'honor' reasons. Paolo Laurana is a leftist professor not convinced of the official truth and starts investigating by himself. He finds some help from a solicitor, Mr. Rosello. While investigating, he is fascinated by Luisa, the widow of one of the victims. But the reality is too different from what Laurana could imagine. Reality includes not only the mafia and corrupt politicians, but also Church connections. The reality is that there could be only one end for Laurana.
