The Adamant is a unique Day Center: it is a floating building. Built on the Seine, in the heart of Paris, it welcomes adults suffering from psychological disorders, offering them a framework of care that structures them in time and space, helping them to reconnect with the world, to regain a little momentum. The team that runs it is one of those who try to resist as much as they can the decay and dehumanization of psychiatry. This film invites us to climb aboard to meet the patients and caregivers who invent their daily lives.
