Help! The local high school drama teacher wrote his own version of Cinderella by combining the Princess's tale with the story of Frankenstein, but the production is bombing: The Fairy Godmother wants to be called the Fairy Goshmother, three new stepsisters must be added to the cast, several actors quit, and the extras are fed up with being extras. Then, after being forced to play a girl, one of the boys worries that if his father, an avid sports fanatic, sees him his acting career will be over. Despite the director's explicit instructions that the Prince's Ball scene must be slow and elegant, the cast speeds it up to super-speed so that the boy won't be seen, but the actress playing the Queen is incapable of improvisation and can't keep up. When Dr. Frankenstein drops Cinderella's brain and replaces it with a cat's brain instead, this insane production changes beyond even the director's recognition.
