A continuation of the film "Familie Buchholz": To Wilhelmine Buchholz, the concept of a marriage based on love is somewhat scary, although she hears again and again that this is the "modern" method to a happy marriage. Her daughter Betti seems to agree, as she shows no interest in her middle class companions; she only loves the painter Holle. To once again restore family harmony, Mr. Buchholz sends his wife and daughters to Helgoland. But Wilhelmine has to return early to Berlin to look after things while Betti and Holle continue onward. On Helgoland, they secretly marry.
