Ricky (Desi Arnaz) develops laryngitis just when he is slated to stage an elaborate floor show for the reopening of the Trocadero Club. Unable to reach club owner Mr. Chambers (Arthur Q. Bryan) in time to deliver the bad news, Lucy takes the bull by the horns and vows to stage the show herself. To help Lucy out, Fred Mertz (William Frawley) calls in some favors from several of his former vaudeville cronies -- and the result is an "up-to-date" musical review, "Flapper Follies of 1927," featuring the world's oldest chorus line! ~ Rovi
