Mafia activity in Naples is at the center of this series, which focuses on internal struggles that follow after the head of a family is imprisoned.
Gomorrah is the inside story of fierce Neapolitan crime organisation the Camorra, as seen through the eyes of Ciro, the obedient and self-confident right-hand man of the clan’s godfather, Pietro Savastano, whose loyalty is tested to its limits. Ciro knows better than anyone what it means to be a loyal clan member. But when Pietro decides to sacrifice many of his own only to make a blood-drenched statement to rival clan boss Salvatore Conte, something dies in Ciro – for one of the many victims of the bloodshed is his foster father Attilio, himself an ever-loyal clan member.
The era of the Savastano clan, who once undisputedly reigned over Naples, seems to be hopelessly over. What lies ahead now is the largest ever power vacuum in the history of the Camorra. The king, Don Pietro Savastano, abdicated, at least momentarily. All the forces involved will suddenly have the chance to have their say and will no longer have to submit to the orders of such a tyrannical boss as Don Pietro. But the latter, although physically and mentally tried by hard prison regime, does not seem willing to lose his empire. Many are now vying for what once was the Savastano kingdom. With Ciro l immortale in the forefront, who from the very beginning will be secretly plotting, testing new and old allies, to finally make the big leap he has always aimed for. A leap which now more than ever seems to be within his reach. Meanwhile Salvatore Conte is now waiting for an answer from the bosses of the clan once close to the Savastano's.
