Psychotherapist Ulf Weiß and his girlfriend Sarah Gievenbeck want to get married. They go to Sarah's parents' house for a weekend. Sarah's father, Heinrich Gievenbeck, a judge at Münster District Court, is extremely pedantic and keeps a close eye on his daughter's well-being. So this weekend he wants to test whether Ulf really is the right man for Sarah. At first Ulf and Sarah have to sleep in separate rooms, and the next morning Heinrich asks Ulf to come hunting with him at the crack of dawn. Ulf does Heinrich the favor. But he accidentally shoots Heinrich's beloved dog instead of the stag.
