The president of a rugby club, Eugenio Sartor, is killed in his home shortly after watching a team training session. Sartor, the owner of the Eagles, had been forced to seek help from his brother-in-law Mazzilli to put the club's finances in order. Mazzilli had thus become the victim's business partner, relinquishing his ownership of a second division football club. Terzani and Rex are initially suspicious of one of the players, Michele Caccia, and then of a criminal implicated in a football match-fixing scandal, Merlo. The latter, however, is shot dead by Mazzilli while trying to kidnap Sartor's daughter. Terzani and Rex have a lot to untangle, between family conflicts, match-fixing and money laundering.

Terzani and Rex investigate when the wealthy owner of a construction company is killed by a rifle shot during a hunting party.
