Jeanne (Emilie Dequenne, 'Rosetta') lives in a house in the suburbs with her mother Louise (Catherine Deneuve, 'A Christmas Tale'), and the two women get on well together. Louise earns her living by looking after children. Jeanne is halfheartedly looking for a job. Louise harbours the hope of getting her daughter a job with Samuel Bleistein, a famous lawyer whom she knew in her youth, but Jeanne and Bleistein's worlds are light years apart. Yet, they are set on a collision course because of an incredible lie that Jeanne invents; a lie that grows into the biggest news and political story of the day.
