Plot

The film follows the plot of the 1974 book. The story centres around Mildred Hubble, who is invariably the "Worst Witch" at Miss Cackle's Academy for Witches. Mildred causes many mishaps, including being late for school, making all of her classmates fall down, Mildred and her friend unintentionally turning themselves invisible, and transforming the class bully Ethel into a pig. The climax surrounds Miss Cackle's notorious evil twin sister, Agatha, plotting to take over the Academy. Ultimately Agatha is foiled by Mildred, and Mildred establishes herself as the hero for the academy.
