The Hansens get a prestigious, wealthy client: Waldau's major estate owner, Frau von Werther, brings I her beloved cat Nefertiti, after having poor Pawel fired as paperboy because the latest edition landed on the pillow-kept feline, waving Nelly's plea to reconsider. Shortly after, a masked intruder kidnaps the cat and demands 30.000 Euros ransom. Just then cousin Ariadne arrives, who advises to disregard the kids as suspect and simply pay up, but the ransom pickup is messed-up as they wrongly suspect the driver, who only came to keep an eye after he and the gardener caught Pawel and klutzy Gustav sneaking on the estate.
