In the fourth part of the story about Dr. Sophie Schöner and Dr. Wu, the two work together again in their old clinic after their "joint practice" project ended sooner than expected. Dr. Wu is standing in for the seriously ill clinic director Professor Fritz, which opens up unimagined career opportunities for him, but he is now also under constant pressure and extreme tension. On top of this, Sophie is pregnant, which further exacerbates the strained relationship between the two. In order to provide a little compensation for the completely overworked staff, Hans feverishly tries to make financial savings that he could credit to his employees as a pay rise. But then everything turns out quite differently.
