In this film, an Italian industrialist who has made his fortune using some shady tactics, unwittingly becomes the victim and entertainment for four retired jurists. These four men, though retired, make it a practice to keep their legal skills sharp. Whenever a suitable villain stumbles across their path, they conduct a trial with all the trimmings. It is a form of play, but these virtuoso lawyers are quite serious about it.
Vaguely inspired to the real story of boss of the Camorra’s bosses Raffaele Cutolo, this is the story of the criminal career of “Il professore” (the professor). He is in prison, and by there he is able to build, step by step, an empire founded on murders and drugs.
