WaPo Duisburg

During Arda's last days at work, Katja Schwarz's body is found on the banks of the Rhine. To the surprise of Arda and his boss Kruppka, Heinrich asks the WaPo for help this time. A message on the dead woman's cell phone leads Arda and Heinrich to Yilmaz, with whom the young woman had spent the last night. During a search of his apartment, the investigators find the crime scene and the case seems clear at first. But the lifeguard denies everything.

An argument between stand-up paddler Dietmar Knaus and scrap dealer Walther Bracht escalates. Jäger and Mark have to mediate. Everything seems to have been resolved, but then Knaus is suddenly found dead in the Rhine. Did Bracht shoot him? Carsten Heinrich has other concerns—a series of ATM explosions is causing unrest in Duisburg. While Heinrich is in the dark about his case, the WaPo is making progress in its investigation. Who is responsible for the paddler's death?

Carsten Heinrich is under pressure both professionally and privately. Klara testifies that she allegedly received a call from Heinrich, which leads to an ultimatum from his superior, Police Chief Jürgen Proske: Terwart must be found. At the same time, Heinrich's mother disappears from the retirement home. To solve the cases, he asks the WaPo for help.

Heinrich assumes it was an accident and quickly transfers the case to the WaPo. The victim happens to be the owner of another electric scooter rental company. For the WaPo, that's too many coincidences. Who had a motive to kill the businessman? His former business partner, with whom he was at loggerheads and whose girlfriend he had stolen, or the environmental activist Olaf Horst, who is already known for his questionable protests? Meanwhile, boss Kruppka has completely different problems.
