Susan Adams, who is employed as a pianist in a Broadway music shop, entertains ambitions for a stage career. Arthur Bennett, famous theatrical producer and successful star-maker, summons her to his office to complain about her noisy piano below him, and she haughtily responds that she will stop if he gives her a chance on the stage. Susan mistakes Eddie Murphy, recently arrived in town, for a flirtatious masher, until she finds him living in her boardinghouse; and their friendship grows when she learns he is a friend of Joe Horn, a saxophonist. Eddie, who plays drums in a cabaret, is disillusioned at seeing Susan with Bennett. When Bennett seeks to ensnare Susan's sister, Marge, Susan proves her acting abilities at his apartment; but learning that Eddie has left for Europe, she confesses her love for him, and they are happily united.
