Director Antoine Blossier orchestrates this adrenaline symphony while Foued Nabba and company infuse the narrative with Marseille's gritty heartbeat.

While the cast sets the stage with raw talent and grit, the story plunges us headfirst into a world where danger and redemption collide.

K.O. delivers a narrative uppercut following Bastien, an MMA gladiator haunted by ring tragedy who is dragged from retirement when his deceased opponent's widow desperately seeks help. Her son Léo has vanished into Marseille's criminal labyrinth, trapped in shadows of menace. Teaming with Kenza, a fiercely determined police officer with justice pulsing through her veins, Bastien plunges into the city's underbelly.
