Cattani uncovers the truth of Marineo's murder, but the knowledge he gains comes at a perilous cost.

Cattani's inquiries center on wealthy industrialists, a pursuit that increasingly complicates his personal life.

Cattani orchestrated a snare for several prominent figures in the mafia, a maneuver that culminated in the abduction of his sole daughter.

Cattani concealed the truth of his daughters' disappearance from both his wife and his colleagues, all while navigating resistance within his own workplace.

Cattani seeks retribution against those who have wronged him.
