In a forest near Stuttgart suburb Mühlenwinkel, Simon Waldeck's corpse is found, with post-mortem wolf bite marks. The locals are bitterly divided over wolves since one was spotted there. Biology and geography teacher Wendelin Sommer champions their return to a natural biotope, against Simon's party: Neighbour Gunnar Hauser, who runs a construction firm, legally disputed an alleged 'informally agreed' 30 000 Euro 'extra' to a cheap land deal, and Simon dumped mother and children's books author Britta Bautze as his mistress, while she also had an affair with Gunnar, who felt stifled by his wife. Meanwhile evidence officer Friedemann resigns for real, despairing captain Kaiser, but helps talking into Jo Stoll to reconsider his untimely resignation as a waste of talent and justice.
