Neige, a single mother of three, regularly visits her Algerian grandfather, Emile, who lives in a nursing home. Neige loves her grandfather, who raised her, and sees him as the pillar of the family that protects her from the toxicity of her parents. The relationships between family members are complicated and they have been holding grudges against each other for a long time. Fortunately, Neige's ex-husband François uses humor to support her. The death of her grandfather not only triggered a family crisis, but also caused Neige to have a profound self-identity crisis. Neige began to take a special interest in her own DNA.
