In Roubaix, Dr Lamarre still practises family medicine, the old-fashioned way. He is one of the last GPs who takes the time to get to know each of his patients, and to follow them throughout their lives. With a resolutely human view of medicine and the Hippocratic oath, he chose to practise here - one of the poorest towns in France - out of principal, and focuses his attention on the most vulnerable in society.

This film is an unprecedented glimpse behind the closed door of his consultation room - into the intimate confessions of those patients who are part of what is known as "La France Invisible", and who are rarely heard with such sincerity and realism.
