Green Fingers (movie, 1947)

A fisherman begins studying to be an osteopath. Although he isn't finished with medical school, he begins treating his landlady's daughter who is believed to have a chronic illness. He seems to cure her, and the case draws a lot of attention, some of it negative because he was unlicensed when he treated her. He still does not have a degree when he marries the daughter and begins practising osteopathy.
