Set against the backdrop of mid-20th century Algeria and France, the film follows three brothers - Saïd, Messaoud, and Abdelkader - who are forced to take separate paths after their family's land is seized in Algeria. Saïd relocates to Paris and becomes involved in the underworld, organizing boxing matches and managing a cabaret. Messaoud enlists in the French army, fighting in Indochina with the hopes of bettering his circumstances. Meanwhile, Abdelkader is drawn to the burgeoning independence movement, becoming a pivotal figure in the fight for Algerian liberation from colonial rule.

As the brothers' lives diverge, a fateful reunion in Paris brings them together, fueled by their shared desire to see an independent Algeria. Messaoud, now disillusioned with the French army, joins Abdelkader in the resistance, employing his combat skills in their insurrection efforts. Saïd, though initially reluctant to get involved in politics, finds himself inevitably entangled in the cause. The tension escalates as their acts of rebellion grow bolder, facing brutal retaliation from French authorities and leading them down a dangerous, irreversible path. The story chronicles their compounded struggles, aspirations, and sacrifices as they navigate the complexities of loyalty, brotherhood, and their relentless pursuit of freedom.
