In this misleadingly-titled 1932 medical (not musical) drama, the resolve of a young surgeon is severely tested. Dr. Felix Klauber (Ricardo Cortez), is a selfless Jewish physician who has grown up in the segregated slums of New York City. Through hard work, he becomes a wealthy Park Avenue doctor. He is called to operate on his father, Meyer Klauber (Gregory Ratoff), to remove a small tumor. But Dr. Klauber makes a fatal mistake, and his father dies on the operating table. Klauber now becomes plagued by guilt and self-doubt and is afraid to practice his profession. His girlfriend Jessica (Irene Dunne) urges him to continue. When it turns out that she, too, requires surgery, his love for her and her entreaties compel him to return to perform the delicate operation. This RKO Studios production was based on a novel by Fannie Hurst.
