All the kids are invited in Werner Elsässer's grand villa for the lavish birthday party he throws for his spoiled daughter. The fashionable shiatsu she gets as gift but can't appreciate is rapidly handed to a younger girl, nobody notices it's utterly neglected. When it's found missing, baseless accusations follow quickly, yet Pawel, Nelly and Cookie spare no effort to search for the truth, even if that means betraying their secret tree house, which the land owner fortunately commends them for fixing on their own. The truth prevails.
