Gitta and her friend Pompom are into a new adventure. The violinist, Herr Kadinsky, has become a good friend and invites the two girls and Gitta's mother on a concert tour to the Czech Republic. They meet a glamorous lady who makes Pompom's clever detective nose itch. Why does Pompom dislike this lady? Attaching herself to the small group of travelers is no reason for suspicion. Or is it? Why, for instance, does her husband never speak? And what is her reason for meeting a dangerous looking man in secret? And how come precious objects vanish where she appears? These are the questions Pompom wishes to investigate. But her curiosity is not welcome and puts her and Gitta in danger of being kidnapped. Will Pompom solve the puzzles and extricate herself and Gitta before they are shipped off to a Czech orphanage?
