Scott Durham, a suave promoter, has made a racket out of producing charity benefits with his wife Evelyn, and then deducting so much money from the gross that very little is left for the charitable organization sponsoring the shows. Johnny Cassidy, Durham's assistant and a song and dance man, works unaware of his employer's unscrupulous methods. When Durham leases new offices in the Marlowe Building, Agatha Marlowe, the straight-laced head of the blue-blooded family that owns the building, threatens to throw the scandalous theater people out. However, those theater people become a blessing to the Marlowe family when the Marlowe Orphanage faces financial reversals and the family decides to hire Durham to stage a benefit show. Agatha relents and allows the troupe to rehearse in the mansion, where her sister Susan becomes smitten by Hector Bates, a middle-aged gentleman who has paid Durham a thousand dollars for theatrical training.
