Bibi (13) scores a once-in-a-lifetime chance to attend the International Witches‘ Gathering. But instead of learning secret spells and celebrating with her friends, they‘re assigned to kitchen duty by the joylessly strict headmistress Servera, who has darker plans in mind. When the young witches sneak into the grand hall, they witness Servera‘s power grab: she demands all young witches be silenced, stripped of their powers until age 21, and sent to mandatory boarding schools. Caught spying, Bibi becomes the perfect example of everything Servera claims is wrong with young witches. But the real chaos begins when Bibi is forced to cook the traditional witch soup as punishment. The enchanted recipe transforms all the senior witches into wild, unpredictable teenagers who unleash havoc across their hometown. Now Bibi must reverse the spell and restore order before Servera seizes control and silences young witches forever.
