We are in a small Heurigen-Café in Vienna. The young singer Fritz Hertzgruber meets a young Danish writer, Jesper Ellekilde, and the two young people become friends immediately. Fritz has been to Denmark as a "Viennese child" and is now an enthusiastic member of the Viennese children's own club. The following evening, the club's annual draw for a trip to Denmark takes place, and Fritz is the lucky one - albeit by detours. Fritz and Jesper are accompanied to Denmark, where Fritz is very much looking forward to the reunion with his foster parents, the composer Emilius Andersen and his wife. They were the sweetest people to their Viennese child, and their home stands in Fritz's memory as the epitome of idyll and harmony.
