The Adamant is a unique psychiatric care centre, remarkable for its floating structure. Located on the Seine in the heart of Paris, it welcomes adults suffering from mental health disorders, offering them care that orients them in time and space, helping them to recover or just keep up their spirits. The team running the centre tries to resist the deterioration and dehumanization of psychiatry as best it can.

Nicolas Philibert's verité-style documentary (a style he has perfected over his 50-year career) invites us to board this unique facility and meet the patients and caregivers who bring it to life every day.
