In the small town of Hinterskreuth, Dr. Quirin Engel is starting a new life because his wife Angelika wants to divorce him. His two children are very excited about his new veterinary practice and regularly visit their father and his animals. They are being supported by their youthful grandmother Gerlinde who keeps being loyal to her son in law. And even Angelika is bothered by the fact that several single women are interested in Quirin. As the new veterinarian has got a different approach and supports ecological methods, the influential local farmers want to teach Quirin a lesson. But Quirin Engel is smart enough to know how to react.
