Lucy finally finds what she believes to be the perfect solution for getting into show business. After Ethel gives her a book about psychological diseases, Lucy pretends to suffer from numerous ailments so that Ricky will feel sorry for her.
When Ricky refuses to appear in Lucy's play "A Tree Grows in Havana," she rewrites it as "The Perils of Pamela." Ricky learns that a Hollywood producer will see the show, so he appears onstage dressed for the original version of Lucy's play.
The two couples have a fun evening singing until the Mertzes go home and hear the Ricardos still singing in the apartment above. Arguments occur between the friends and, to break out of their lease, the Ricardos invite Ricky's band over to play.
When Lucy learns that there is an opening in one of Ricky's acts for a ballet dancer, as well as a burlesque comedienne, Lucy decides to take a ballet class, which leads to disastrous results.
