Investigating the death of his cleaning lady's nephew, Coliandro uncovers an extreme fighting ring involving a series of wrestlers who are systematically drugged to relieve pain and fatigue. Helping him unravel the case is Veena, a beautiful and athletic fighter who escaped from this group of modern-day gladiators.

Coliandro believes that Gamberini has relapsed into the old habit of gambling and, trying to help his friend, infiltrates a clandestine gambling ring. In doing so, however, he blows up an investigation already underway promoted by Longhi and puts Giacomino, who he has hired as a consultant, Gamberini and himself in grave danger. Thanks to the help of Ambra, the girlfriend of one of the criminals, the inspector still manages to get away.

Chief Inspector Vittoria Martello asks Coliandro to join the "Team", a team of superpolicemen who are opposed by Gamberini and other colleagues for their brutal and unorthodox ways. And in fact, thanks to Coliandro's entry into the Team, it turns out that the group is nothing more than a new gang of drug dealers and exploiters inspired by the action of the Banda della Uno Bianca.

Coliandro is contacted by a girl who needs help: her boyfriend disappeared after stealing a smartphone and finding footage of a gang of Russian criminals inside. The young woman turns to the inspector because she often hears him mentioned by her aunt, the deputy prosecutor Longhi, who however believes that Coliandro is not a good policeman.

Coliandro witnesses a clandestine race between two motorcyclists but one of them loses control and causes the other to fall, who is killed. The inspector and Buffarini manage to save the motorcyclist responsible for the accident and find refuge in the police station but will have to deal with the bloodthirsty boss of the area, brother of the deceased pilot, who seeks revenge.
