The series Gomorrah - The Origins explores Pietro Savastano's youth in the 1970s, in a Naples undergoing a transformation, poverty-stricken and plagued by cigarette smuggling. The story begins in 1977 with a very young Pietro, the son of no one, growing up as an adoptive brother in a family in the poorest part of Secondigliano. A street kid, he scrapes by as best he can, dreaming of a well-being that is still denied him. The story unfolds through Pietro's loss of innocence, along with his brothers and lifelong friends, their ambitions, and his first great love, which, like that of every teenager, will be wild and passionate. His encounter with Angelo, known as 'A Sirena,' the regent of Secondigliano, marks his entry into the world of crime. Through violence, alliances, and betrayals, Pietro discovers the price that life takes.
