Marcia wins the lead female role of Juliet Capulet in the school production of Romeo and Juliet opposite Harold Axelrod as Romeo Montague. Peter and Jan are given parts as palace guards, and rehearse their brief roles repeatedly. Marcia had auditioned for the part of the nurse and feels she isn't good enough for the lead female role. The family makes an effort to encourage Marcia, but her ego grows and she becomes unmanageable. Marcia is heartbroken when her diva-like behaviour results in her dismissal from the play. At the last minute, when the girl cast as Juliet's mother Lady Capulet gets the mumps, a contrite Marcia asks to be given the role and promises she will act in a professional and courteous manner.
