Just before reaching the final stop in the West, Rudolf opens up about the past he has tried to forget. Sabine, the gymnast, makes a brave decision, and Sascha remains on the train without his friends.

Elling is having major financial problems, and Simon Jäger makes it clear to Peters that Elling, Lona, and Jaspers need to be kept away from Marnow at all costs. At the end of this clip, there is a preview of what's to come in the next episodes.

The impending farewells now become an unchangeable reality at Ludwigsstadt train station, the last stop before the border.

Sascha confronts Rudolf, but he gets no certainty regarding his suspicions. Just before crossing the border into the east, one more person decides to leave the train.

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.
