Edmond Vidal (Gérard Lanvin), a former car thief, aspires to live peacefully as a happy grandfather. When he hears a member of his former gang has been imprisoned (Tchéky Karyo), he feels a strong sense of duty and decides to go to his aid, even though he's putting his new life at risk. Reminiscing about their youth spent as legendary armed robbers, the Lyonnais Gang goes back to work. Their methods haven't changed since the 1970's, but the code of honor is still the same: it is better to die than to betray the gang.

Former cop turned director Olivier Marchal returns to the subject of the great gang, after the movie 36, Quai des Orfèvres and the series «Braquo», but where he usually tells his stories from the side of the police, this time he focuses on the other side. Well put together, but full of stereotypical portrayals of gypsies strung with gold chains and hairy chests peeping out from open-necked black shirts. The film was inspired by a real gang that held sway for 40 years in Lyon, offering a very noble portrait of an old school thief that one hopes will get away in the end. A shame that the flash-backs are always drenched in violins that seem to make up the entire string section of the Vienna Philharmonic.
