Lino Alban Lenoir, a skilled mechanic, dreams up a bold plan: build an armored Renault Clio that can plow through a jewelry store to rob it and help his foster brother Quentin pay a debt. The stunt goes further than anyone anticipates, blasting through walls and leaving chaos in its wake. Quentin escapes the immediate danger, but Lino is captured and ends up behind bars. On the outside, a determined Charas Ramzy Bedia a sharp, unyielding police detective, puts Lino on day release and enlists him to join a covert drug squad that hacks the system from the inside—retooling police cars to chase drug runners by ramming them at high speed. The arrangement is uneasy but efficient, and before long Charas manages to secure a pardon for Lino and a modest garage where he can work and stay useful.
As the pair digs into Quentin’s potential ties to the ruthless go-fast operation, they confront a dangerous echo of their own past. Two corrupt members of Charas’ squad—Areski Nicolas Duvauchelle and Marco Sébastien Lalanne—ambush Charas and kill him, forcing Lino to improvise a perilous escape. The shell of an investigation grows darker as the drug runners seem to have sabotaged Charas’ Renault 21, leaving no clear link to the crime. Lino is soon cornered again by the police, where Areski tries to pressure him into lying, and when Lino refuses, the frame-up tightens its grip, accusing him of a murder he didn’t commit. He fights his way out of a brutal interrogation and barrels through a gauntlet of officers, driven by a stubborn need to clear his name and uncover the truth.
Desperation drives Lino toward Julia Stéfi Celma, his lover and a tenacious member of the same law-enforcement circle. She confronts him in a tense confrontation, and their relationship becomes a complicated thread through the maelstrom of corruption. As Lino pieces together the puzzle, he realizes that the burnt car recovered by the police isn’t Charas’ Renault at all, a clue that reframes the entire investigation. With the help of Julia’s own courage, he and Quentin assault the drug runners’ turf, taking down armed opponents and reclaiming time and space to plan their next move.
The trio—Lino, Quentin, and Marco—pursues a hidden Renault, which Quentin identifies as the key to the case. Quentin’s testimony and other gathered evidence push Julia to trust Lino, and she helps him slip away from a pursuing, compromised unit. The Renault’s location is finally revealed at a farm hideout, setting the stage for a dramatic confrontation. But the moment of truth comes at a cost: Marco fatally shoots Quentin before Lino can intervene, and the dying revelation of the Renault’s hiding place comes from Quentin himself, threading the last bit of truth into the danger still chasing them.
Areski intensifies his pursuit, rallying the corrupt brigade to strike at Lino before he can reach the headquarters with the crucial evidence. Undeterred, Lino mounts a daring last stand with the red Renault turbo, outfitted with bullbars, and uses it to smash through barricades and collide with the corrupt forces in pursuit. A cat-and-mouse chase culminates in a brutal crash where Areski himself is pressed to the edge as the car catches fire. Lino manages to steer the burning machine to the garage where technicians extract the fatal bullet and secure the evidence that could topple the corrupt operation. With the danger finally receding, Areski goes on the run, and Lino is joyfully reunited with Julia, rejoining his team with a renewed sense of purpose and justice.
