Juliane falls off a cliff and plummets to her death. Police officer Karl Albers doubts that it was an accident, so he marks the cause of death as “undetermined” in the report before sending it to the West. Investigator Nadja Paulitz from the State Office of Criminal Investigation is sent to the East to investigate with him. Karl and his commanding officer, Captain Wieditz, work with Nadja objectively, while district leader Egon Pölz does everything in his power to quickly close the case and be rid of the unwanted visitor from the West as fast as possible.
