S1, E4: Right from the morning, Inspector Korbinian is in a bad mood. A stranger has parked their car in the middle of his yard. The car wouldn't prevent Korbinian from driving the tractor; he is just jealous that his colleague Ulrich is constantly picking up women. But on that day, of all days, Korbinian falls in love with a woman named Elfie. Unfortunately, Elfie is the girlfriend of a suspect in a new murder case. The cook of the Dudelberger, a bistro in Rosenheim, was shot dead at night. The main suspect turns out to be the owner, Kilian Gollinger. He owed the murdered man a fair amount of money. The fact that Elfie gives her friend Gollinger an alibi for the time of the crime is particularly bitter for Korbinian. He suspects that Elfie is not giving him the alibi voluntarily, but out of fear of Gollinger. Besides, Korbinian has really fallen for the attractive, fitness-conscious Elfie. As a result, Korbinian even starts to go for evening runs in the woods, which earns him sneering comments from Ulrich. In this case, however, his search for the truth and his wishes for love end up forming a happy symbiosis, because Korbinian succeeds in persuading Elfie to retract her alibi. Ulrich follows his own trail, because at the time of the murder, an old mill near Rosenheim burned down. Ulrich has a strong suspicion that the two events are connected, especially since the owner and Gollinger are old friends. A gasoline can, a gas station video, and ultimately Korbinian's ill-fated love finally help solve the case.
