Mimouna lives with her younger sister, Salima, and older brother, Hamid, at her parents' home, Algerian immigrants, in the Parisian suburbs of the 1990s. The father works on construction sites, the mother stays at home. Exiled, far from their close family, time is spent waiting for the vacation, the return home for a few weeks. A sister has disappeared from the house. She ran away. Salima, cheerful, dynamic and rebellious, is already dreaming of leaving with someone. Hamid, of a rather sweet and dreamy nature, is in conflict with his father who expects him to react more violently and authoritatively towards his sisters. To escape this heavy atmosphere, Mimouna does not run away, but she lies. She makes her parents believe that she works in a hospital and that she often has guards to look after her.
