Ich liebe dich - April! April!.

The law student Caroline and the assistant professor Tom are husband and wife, but they keep their marriage a secret. While Caroline is afraid of annoying her mother Hella who ever since her divorce twenty years ago distrusts men in general, Tom dreads the criticism of his professor, a family law specialist who objects to the concept of marriage. By chance, Caroline gets hold of some juicy information: Her mother and the professor used to be a couple and she is their child. With almost missionary zeal she addresses herself to the task of convincing the two grown-ups to get back together. In the process, however, she steers both her academic studies and her own marriage into a crisis.
