Kay Kyser (Kay Kyser) and his band return home to North Carolina after a long USO tour. Instead of taking a rest, the band plays at a nearby shipyard. There, Kay meets Julie Carver (Ann Miller), a fantastic singer whom Kay mistakes for the shipyard owner's daughter. Kay's regular singer, Georgia Carroll (Georgia Carroll), wants Julie to substitute for her so she can leave the band and get married. Kay agrees only after Julie is able to lure a wealthy relative to their show.
