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.

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.
