K.O.

In Marseille, a former mixed martial artist named Bastien tries to live a quiet, edged life after years of headlining brawls. His peace is shattered when the man he once killed in the ring is connected to a brutal criminal past that refuses to stay buried. When that man's son vanishes, Bastien is drawn into a high risk pursuit alongside a tense coalition of rivals and allies who know they can't trust anyone. He confronts the city's shadowy streets where informal gyms double as fronts for violent gangs and every lead carries danger. The city itself becomes a character reflecting Bastien's inner conflict and the price of returning to a life he hoped to leave behind.

Directed by Antoine Blossier, K.O. brings together creators Louis Aubert, Guillaume Lemans and Clément Marchand to adapt their concept for a Marseille set action drama that pairs hard edged fight scenes with a noir mood, set against the city's underbelly.

Box office data for K.O. has not been publicly released, so worldwide grosses and overseas performance remain unreported at this time for now.

As of now there are no announced major awards for K.O., and the film appears positioned as a punchy genre piece rather than a prestige project. It has drawn attention for Ciryl Gane's performance, Blossier's brisk direction, and the practical fight choreography that keeps action grounded.

Critics note a taut pace and a stark take on guilt and redemption as Bastien wrestles with the consequences of his past while trying to keep another family safe. The story threads loyalty, resilience, and the cost of violence through Marseille's gritty streets. Thematically it probes how guilt can fuel determination without absolution, and how loyalty can blur lines between protector and aggressor, a tension that mirrors Marseille's own dual nature as harbor and battleground.
