Hilfe, ich hab meine Lehrerin geschrumpft

Eleven-year-old Felix Vorndran (Oskar Keymer) has a new school and a new life, but things take a strange turn when he accidentally shrinks his strict principal, Dr. Adelheid Schmitt-Gössenwein (Anja Kling), to just 15 centimeters in height. With the principal now tiny and frantic, Felix and his best friends Ella (Lina Hüesker) and Mario team up to find a way to reverse the spell before the school's vice principal discovers what's happened.
