Eddie and Albert enlist the aid of a friend, Elsie Hammerdingle (Marion Hutton), a taxi driver, to take them to the mansion. While they are upstairs attempting to fix the leak—but flooding the room instead—Peter Evans (Kirby Grant), a guest dressed as a cab driver, mistakes Elsie for another costumed guest, despite her insistence that she really is just a cab driver. He winds up inviting her to another gala event, Mrs. Winthrop's (Margaret Irving) estate Briarwood, where a valuable painting, "The Plunger" (a heavy gambler), is to be unveiled.
