Samy (Nicolas Cazalé), a young Franco-Algerian, hits a policeman at a roadblock and must flee France. He takes refuge with his grandfather (Mohamed Majd) in Algeria. But he does not speak the local language, and everything is strange to him, even members of his family: Nadia (Amira Casar) his cousin, a pregnant widow; and Qu'Issam (Kheireddine Defdaf) another cousin, who was expelled from France, and hates everything French.

Samy will never give the reason for his presence, but the chaotic climate of the country will revive the chaos that is in him.
