The Corsican Line - Season 1 (2025)

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.

Reda reconnects with his childhood sweetheart, Alexandra. Now married to Jean-Do Guerrieri, she is still in love with him. Reda's father is forced to partner with Carlotti. Undercover in Lupino, Ines gathers valuable information while protecting Reda. The latter decides to set up his own business without informing the Plaine gang.

The anti-Mafia unit continues its investigation into Lupino's deal. Ines finally receives congratulations from Judge Maertens. Reda continues his parallel deal and arouses the suspicions of the anti-Mafia unit, which begins to investigate him. Eva Maertens does not understand why he does not appear in any of Ines' reports.

Ines is forced to confess her secret to Albertini. Eva Maertens meets Reda and tells him that she suspects Jean-Do Guerrieri deliberately caused the accident in which Reda's father was injured. When questioned by the police, Alexandra will do everything she can to protect her daughter's father.

After clearing his name with the police, Alexandra asks Jean-Do to leave their home. Rachida, the mother of Ines and Reda, returns to Bastia following a tragedy. Having been estranged from her son Reda for many years, she demands that Ines let her speak to him. Meanwhile, Reda seeks to meet César Carlotti...

Reda is arrested by Judge Maertens as part of the investigation into the ambush on Jean-Do Guerrieri. The net is closing in on the brother and sister. Carlotti discovers that Ines Amrani, the judge investigating him, is Reda's half-sister.
