On an abandoned industrial site on the outskirts of Berlin, a homeless man is found dead with bite marks. He may have been attacked by a wolf. Bonard and Karow use this information to scare off a wilderness enthusiast. This is Bonard's last case before her retirement, and on a whim, she joins wilderness instructor Professor Dara Kimmerer, leaving the case to Karow. While Bonard undergoes survival training in the forest, Karow discovers that the victim was murdered and encounters the mysterious man from the woods again. The investigative team delves into the world of survivalists and preppers, as everyone prepares for the end in their own way.
