Träum' nicht, Annette

French teacher Annette Müller has two ardent admirers who are constantly urging her to marry: diplomat Klaus and engineer Theo. But she can't make up her mind. Then a third one joins them, the pianist Hans. Sometimes she dreams of Klaus, sometimes of Theo. And although she is angry that Hans has taken up residence in her boarding house, she can't stop herself from dreaming about him too. When she asks him, of all people, which of the other two she should marry, there is a big row between them - and she realizes who the right man is.
