The series is an adaptation of the film Romanzo Criminale (2005) directed by Michele Placido. The first series quickly achieved cult status in Italy.
This is the second fiction series after Quo Vadis, Baby? that was produced by Sky and broadcast on Fox Crime, Sky One and on Sky Arts with English subtitles in 2012.
The series is partially based on Banda della Magliana, a 1970s criminal organization active in Rome led by three friends, Libanese, Freddo and Dandi, who attempted to merge local gangs in a mafia feud like sicilian and neapolitan organisations. Their history matched with right-wing terrorism groups, deviated secret service, masonic lodges and financial affairs.
