The great magician brings three of his young sorcerer's apprentices to his annual visit. And from the first moment on, one question dominates the daily life at the academy. Which is better: witches or wizards, boys or girls, women or men? To prove what is supposedly already clear, Egbert Hellibore, the great magician, suggests a contest in which two sorcerer's apprentices compete against two young witches. Mildred, who has long since become the victim of events again and is actually grounded, witnesses a diabolical plan of the young wizards.
