Lilly can hardly believe that she has been asked to play the part of Gretel in the school play. But there are problems. Kendall, who plays the part of Hansel, thinks Lilly is too tall to play his little sister. And Lilly's best friend Minna can sing beautifully, but can't cackle well enough to be the evil witch. They need someone to play the witch who can sing, act and cackle - Lilly! Lilly wants to help Minna, but she is not so sure she wants to give up being Gretel.
