Miss Lewis, the Ricardos' elderly neighbor, requests Lucy's assistance in getting the attention of Mr. Ritter, the elderly grocery man whom she is sweet on. Lucy readily agrees to give Mr. Ritter a dinner invitation for Miss Lewis. The first complication arises when Lucy shares the news with Ricky, who spanks Lucy for interfering and makes her promise to give the note back to Miss Lewis. But, when Lucy proceeds to give Mr. Ritter the note anyway, he misunderstands and thinks the invitation is from Lucy herself. This leads to an unsuccessful plan by Lucy to discourage Mr. Ritter and Ricky's telling Mr. Ritter that he can have her. In spite of all these unintended mishaps, Mr. Ritter and Miss Lewis do in fact wind up together, never to be seen on any future episode.

Lucy is busily writing the script for the play that her women's club is going to put on, a little something called "A Tree Grows in Havana," and she needs Ricky to appear in it. When Ricky sees the script, he immediately declines. So Lucy is then left with no alternative but to get Fred to agree to do the role. Deciding that Fred wouldn't be very good for portraying a Cuban character, Lucy decides to rewrite the play so that it is set in England. Later, however, Ricky decides that he wants to be in the play when he hears that some very important sponsors are going to be at the women's show. So he manages to trick Fred into giving him back the role. But Ricky doesn't know that Lucy has rewritten the play. This leads to some pretty disastrous results.
