Berlin-Schoeneberg: Doctor Peter Brockmann (Günter Pfitzmann) has his practice for general medicine in the middle of the neighbourhood in Zietenstraße. He and his doctor’s assistant Gabi Koehler (Anita Kupsch) lovingly take care of the small and big needs of their patients. But medical concerns are not the only issue. Even with private problems, the doctor is always on the spot. But the people in his neighborhood love and worship him for it. Because it makes no difference between private patients and statutory health insurance patients. Unfortunately, he sometimes overshoots the mark a bit, so that his doctor’s assistant sometimes has to slow him down. Because also privately and in his love life things sometimes get quite turbulent.
