A portrait of Sabine Bonnaire, a 38-year-old autistic woman, filmed by her sister, the French actress Sandrine Bonnaire. Through personal footage filmed over a period of 25 years, it is revealed that Sabine's growth and many talents were crushed by an inadequate care structure. After a tragic five-year stay in a psychiatric hospital, Sabine found a new lease on life in a home in the Charente region.
