The story starts with Bastien, a former MMA champion who shuts himself away after accidentally killing his opponent, Enzo Prince, during a professional fight. Emma, Enzo's wife, and Leo, their son, were there to witness this tragedy. As he feels emotionally broken and guilty, Bastien quits being in the public eye and goes to work in a salt mine.

It has been 2 years since this tragic incident. Leo, who is now a troubled teen, goes missing after joining a local gang led by the dangerous Manchour brothers. When Emma calls Bastien, he feels responsible and agrees to help her find Leo.

Soon, Bastien meets police captain Kenza Alaoui, whose brother was killed by the same criminal gang. As they face constant danger, dishonest government officials, and emotional challenges, their personal goals align.

They track Leo through Marseille's criminal underworld, getting into a fight at a nightclub, and finally finding him hiding with his girlfriend, Inaya. The Manchour gang attacks just as they are about to run away, but the police stop them. Leo tells the police what he knows later at the station. However, the Manchours fight back by breaking into the building.

In the film’s intense finale, Bastien and Kenza each defeat one of the Manchour brothers. A police mole is exposed and shot. Leo survives, and the story ends with him reunited with Emma and Inaya. Bastien and Kenza, though wounded, walk away with peace and closure, ready for a new beginning.
