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.

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.

Two small-time criminals, Libano and Freddo, team up to kidnap a wealthy baron. With the ransom money, the leaders of the two gangs plan a partnership that will conquer Rome: the Gang is born.

The drug trade is the starting point for their rise in the criminal world. But the Lebanese struggles to manage his undisciplined men, first and foremost: Dandi.

Thanks to drug dealing, Libano and his associates patrol neighborhoods and make enemies. Scialoja realizes that Patrizia is the key to tracking down the criminals, but the attraction between them complicates the investigation.

Money in spades and unfinished business for the Gang. An old boss, the Terrible, wants to nip it in the bud: a brutal war for power is about to hit Rome. Scialoja is the first to sense it, but he has no proof.

Mysterious emissaries contact Lebanon to find Aldo Moro; Freddo, opposed to political interference, distances himself. Meanwhile, Terrible provides Scialoja with evidence to frame the Gang.

Libano and the others, all in prison, wonder who could have betrayed them. The answer is simple: there can only be one man behind the unscrupulous Scialoja's move. But their hegemony continues even from behind bars.

The Gang celebrates their return to freedom at Scrocchiazeppi's wedding, but there are problems to sort out: Dandi has dangerously lost his head over Patrizia; Freddo settles scores with Terribile.

The Gang is the absolute master of the underworld, and even the Mafia seeks complicity by arranging a meeting between one of its emissaries and Lebanon. But the reinforcements don't end there: a neo-fascist, Nero, and a businessman, Secco, also ally themselves.

Despite being at the height of its power, the Gang seems to be losing its team spirit, so the Lebanese organizes a coup to pull off together.

The Lebanese and Dandi end up in jail again and it's up to Freddo to take command of the Gang, which has more and more enemies.

The nephew of a former boss is killed, and "the Puma" becomes convinced that Lebanon is the culprit, risking his life despite the Gang having nothing to do with it this time. Meanwhile, the Cold One considers leaving for good.

Lebanon, burdened by debt and addicted to cocaine, breaks off relations with Cold, who decides to leave the country. The Gang seems to have reached the end of the line, but unexpected news changes the game.

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.

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.
