Gerhart Ramm is a simple minded farmer's son with much an interest what life means downtown. When he tries to spend the night in Hamburg, he gets no attention at first. But there is Chantalle who is kind of amused by Gerhart's behaviour.

After his training as a policeman, the young, shy Köppe is transferred to a northern German town. Unfortunately, in an area where fox and rabbit say goodnight, there is little for a lawman to do. So Köppe kills time with the search for mysterious cow murderers, flirting with two attractive women and befriending a likeable petty crook.
