Visiting her two sisters and brother, singer Petey Brown lands a job at small-time-hood Nicky Toresca’s nightclub. While evading the sleazy Toresca’s heavy-handed passes at her, she falls in love with down-and-out ex-jazz pianist Sand Thomas, who has never quite recovered from an old divorce. While solving the problems of her sisters, brother and their next-door neighbor, the no-nonsense Petey must wait as Sand decides whether to start a new life with her or sign on with a merchant steamer.
