In this musical comedy of errors, David Brassard, Sr. (William Collier, Sr.) has his heart stolen from him by a conniving, gold-digging nightclub singer named Josette (Tala Birell). Brassard's two sons, Pierre (Robert Young) and David Junior (Don Ameche) are both horrified and vow to lure the temptress away from their dad. However, they somehow become convinced that the woman in question is Renee LaBlanc (Simone Simon), who is merely posing as a chanteuse in order to help out her friend Barney Barnaby (Bert Lahr), whose nightspot is in trouble. In time, Pierre and David Junior both realize that they've been chasing the wrong woman -- but they also realize that they've both fallen in love with her. The supporting cast includes William Demarest and Lon Chaney, Jr., the latter only a year before One Million B.C. would reshape his career and make him a star of horror and science fiction films.
