Regardless of where you look, there is only chaos: Bibi (Lina Larissa Strale) and Tina (Liza-Marie King) embrace a pretty naughty rogue, who soon turns out to be a girl, followed by her own family. His father is so unlimited and stubborn that even Bibi does not object to her witchcraft. Meanwhile, Schloss Falkenstein is under reconstruction, so the count (Michael Mayerts) is completely overloaded, and Alex (Louis Held) wants to organize a music festival on the territory and, consequently, resist his father. And then, to the beginning, Tina is kidnapped. With all the confusion, friends should work together to make a difference, because only together do you move something, and not with witchcraft.
