The LKA investigator Felix Murot (Ulrich Tukur) lives alone, a forever bachelor who has neither sought nor found the woman who suits him. He dresses well, but only has one suit, which he always wears, and at most changes his shirts every once in a while. His gruff, sometimes cynical nature isn't for everyone, although he can be comical at times. He has a charming, bright side and a dark, unpleasant side. HisThe only confidante at the LKA is his secretary Magda Wächter (Barbara Philipp), who always has his back with her gruff charm. Murot has frequent headaches, and a routine check-up reveals a tumor in his brain. Doctors can't tell if it's dormant or developing. Murot refuses radiation and takes pills, he is afraid and represses.
