Sir Charles Bryant sends his daughter Ann to Europe in order to break up her romance with Larry Granger, a singer of ill repute. At the London airport Ann becomes acquainted with Billy Universe and the Satellites, a rock and roll group who are en route to Brussels. Fog grounds the plane, and Billy and the boys take Ann on a nightclub tour of London in hopes of finding her lover. They find Larry romancing one of the club's dancers. Ann realizes that Larry is not for her; she is reconciled with her father; and the boys depart for Brussels.
