Plaine orientale

A few days before his release from prison, Reda receives a visit from his half-sister Ines, whom he barely knows. She has just joined the anti-Mafia unit in Bastia as a judge. This department, headed by Judge Maertens, is investigating the murder of a mayor who is believed to have resisted the Mafia. Upon his release from prison, Reda approaches his former gangster friends, but he realizes that there is no longer a place for him and finds himself relegated to the drug dealing spot in the Lupino housing project.

After regaining his place in Lupino's deal, Reda realizes, along with Nacéra, that Taracci, one of Guerrieri's men, is swindling them. Ines and Judge Maertens continue their investigation separately, and both find evidence implicating the same company: Corsica Distribution.

Judge Maertens learns that Taracci is linked to Carlotti's gang but also to Lupino's trafficking operation. Ines is sent to stake out the location with Albertini. When Carlotti realizes that Reda is threatening his business, he decides to go after his father. This is too much for Reda, who makes a radical decision.
