God Plays Sax, the Devil Violin (2004)

They are patients in a psychiatric hospital in Romania and marginalized persons whose social status has been removed. You think they will only say crazy things, but you don't want them to be like ordinary people, be good, love, and even create often... It's just that all this is confined to the hospital wall. The title is a gimmick, just one sentence from a song sung by the patient in the film.
