Once and for all, the friends want to stop the landowner who has escaped with the Amber Room's most precious object: the Fabergé egg. With Johannes behind the wheel of the old rat-catcher car, a wild car chase begins after the landowner and his sons, who have planned to escape in a plane. But an accident puts an end to the car chase, and Nanna must use other horsepower to stop the landowner from escaping.
