Personal desires and political reality are forcing all involved to make decisions now. Willi and Elke have found a solution for themselves, but the adults are having a harder time finding common ground.

The Alps are a vast mountain range spanning central Europe, from Slovenia to France. In the first part of this series, we meet photographer Matevž Lenarčič, who captures this region from the air.

In the first part of the season "Posthum" ("Posthumously"), we get a brief recap of what has happened so far. Then we follow Lona, Jasper, and Elling to the forensic institute, where the pathologist shares the results of his examination with the team, and the investigators speculate about the course of events.

Elling, Lona, and Jasper continue discussing the investigation results. Lona has discovered something that justifies a trip to Marnow, where Beck regularly stayed at a specific campsite once a year. Lona and Elling set off, leaving Jasper to conduct further investigations on site.

Elling seems to notice that something is going on between Lona and Sören Jasper. When Elling visits the forensic pathologist, he learns something there that changes everything.
