Big city bull Killmer has proven himself professionally in a covert operation, but privately put angry. That is why he is transported away: to the country, to the Eifel, far away from his usual hunting ground. In the very clear town of Monreal, local police officer Kati Biver has just applied to the big city because there is too little going on. Kati is by no means happy that she suddenly has a boss in front of her nose and finds Killmer's casual city behavior extremely provocative on the one hand.
