Rome, 1980. Having regained their former unity, the gang has only one goal: avenging the Lebanese. After a chaotic manhunt, the possible perpetrators are identified.

The gang has begun its revenge, but Commissioner Scialoja is pressing them. Freddo, Dandi, and Bufalo organize an ambush to track down one of the Lebanese's alleged killers.

The gang hatches a new plan to kill Maurizio Gemito after the first ambush fails. The task is assigned to Dandi, who must regain the trust of his companions.

The police raid Patrizia's brothel and arrest her. During the search, Scialoja uncovers a crucial clue to the possible collusion between the secret services and the gang. Meanwhile, Dandi is torn between remaining loyal to his comrades or forming an alliance with Sardo.

The gang is in dire straits: Commissioner Scialoja has seized their arsenal and is gathering crucial evidence. Meanwhile, Don Mimmo, the Camorra boss, is plotting revenge and trying to frame Freddo. To protect his friend, Dandi turns to Uncle Carlo.

Solidarity among the gang members falters: Bufalo, on trial, trusts only Freddo, who advises him to file for insanity. Dandi works covertly to uncover Patrizia's hideout. Scrocchiazeppi must find a solution to the family debts.

Hard times for the gang, which is losing power. The drug trade is no longer a reliable source of income because someone is running a parallel business. While the Cold One is desperate to uncover and punish the "betrayer," Patrizia wants to forge her own destiny.

The gang is torn apart by quarrels and betrayals. Freddo ends up in prison, Bufalo seeks revenge on the increasingly rich and powerful Dandi. Commissioner Scialoja tries to exploit the moment of confusion to launch a decisive attack with the help of an unexpected witness.

The gang ends up in court. Thanks to the key testimony of one of the criminals, Scialoja manages to arrest them. The network of agreements and friendships allows Dandi to be exonerated due to lack of evidence. But in the post-sentence confusion, two other gang members escape.

Several years after the trial, Freddo returns to Rome for personal revenge. While Scialoja continues to harass the gang's survivors, Rome prepares to witness an all-out war, with no holds barred.
