A sensitive documentary about Sabine, an autistic woman of 38. This film is the directorial debut of her sister, the well known French actress Sandrine Bonnaire. Over the course of 25 years Bonnaire has recorded the everyday life of her sister. That footage forms a moving portrait revealing her sister's talent, which has been repressed due to an incorrect diagnosis and inappropriate treatment. Sabine's condition deteriorates when she stops spending time with her siblings, who have moved away. As the disease progresses she becomes increasingly aggressive, eventually beginning to attack her mother. From the age of 28 to 33 she is locked up in a psychiatric institution, a move which led to tragic and irreparable results. Today she lives in a family–style therapeutic home where clients with different forms of handicap receive personal care. This intimate picture draws attention to the lack of specialised institutions and shows the harm that can be caused by unsuitable treatment.
