The murder of her colleague Yela Antic does not leave Ellie alone: she wants to call Gedeon to account for the theft of the murder weapon. Meanwhile, Gedeon delves more and more into his past.

A burned woman's body is found in Austria. Instead of Ellie, her new colleague becomes a liaison officer in the German-Austrian Soko. Gedeon distrusts his colleague Rafael Lutz.

Ellie and Gedeon are working together again, but in secret Gedeon is looking for the artist Oskar Koschlick. After another murder, Ellie receives an important clue from journalist Charles Turek.

Another murder points to a pattern - the perpetrator profile fits the main suspect. At the Gössen construction site, activists and police fight each other. Gedeon comes across a legendary figure.

A supposed motorcycle accident on the pass road leads Ellie and Gedeon to a ritual spot in the forest. They learn more about the legend of the Schinder Jackl. Turek makes a confession to Ellie.

During an operation in the forest, the police are confronted by a mysterious man who does not reveal his name. What does he have to do with the murders? Gedeon gathers his last strength to find Koschlick.

A house search ends disastrously and still the officers do not know how the suspects and the murders are connected. To solve the case, Ellie and Gedeon go beyond their limits.
