Charlie Bumpers has his heart set on playing the role of the evil Sorcerer in the fourth grade play. He's even got the laugh down pat: Mwa-ha-ha-ha! But his dreams of villainous stardom go up in smoke when he finds out that Mrs. Burke has cast him as the Nice Gnome! Determined to rectify this terrible injustice, Charlie concocts one plan after another, but nothing seems to work.
