By chance, Max learns that his father's taxi is repeatedly in Leon's parents' garage because of a defect. Max persuades his parents to apply with him as candidates for a family quiz to win money for a holiday or even a new car. But when the station accepts the application, the work really begins, because all the quiz questions will revolve around gardening and botany. Through hard cramming, the three try to acquire as much knowledge as possible in their own way before the broadcast date. Emilia's method of visual learning does not work for Max. But Barenboim discovers that Max has a very good acoustic memory and suggests that he cram the material musically.
