Supported by their mother's inheritance, Ysé, a young woman suffering from social anxiety, and Simon, her narcoleptic brother, are stuck in a relationship of interdependence and lead a life of idleness, devoid of meaning and bearings. On her 21st birthday, when she finally has access to her share of the inheritance, Ysé learns that an additional clause is in the will: to do forty hours of volunteer work at the Centre Béatrice-Caron, an eponymous organization founded by their mother. This ordeal will push the young woman to face her anxieties, her mourning and to question her way of life. Ultimately, she will have to choose between the toxicity of comfort or emancipation.
