WaPo Duisburg - Season 4

Several containers are broken into, and the WaPo is called to the terminal. Carsten Heinrich and police cadet Klara Proske are also on site. During the investigation, the WaPo encounters the burglar. They find a fortune cookie in his jacket, which provides a clue, but he himself escapes. When Klara is kidnapped, Heinrich asks the WaPo for help in finding her discreetly and clarifying the background to the break-ins.

Chief Kruppka asks the team to stay out of criminal investigations during an internal audit. But when a body is found in the water during a traffic lane check, the WaPo secretly continues its investigation.

Carsten Heinrich dismisses the case as suicide. When the auditor uncovers the investigation, the future of the station and the solution to the case are at stake.

Mark and Klara move into their new shared apartment. While Klara repairs the washing machine, the WaPo team is busy with their next case. Expensive yachts are being stolen around Duisburg. Jäger and Mark lie in wait at the marina to catch the perpetrators in the act. Mark is kidnapped in the process. The team does everything it can to solve the case and rescue Mark—even if it means relying on Carsten Heinrich's help. 

The WaPo investigates the murder of Rasmus Lorenzen, whose body is found on the banks of the Rhine. He was apparently killed in his villa and then disposed of in the Rhine. Nadine finds a threatening letter that leads the WaPo to the victim's housekeeper, Isabel Martinez. Rasmus apparently also exploited his position of power in relation to his service providers and made Isabel work for him for free under a pretext. Did she finally make good on her threat and kill Rasmus in a fit of rage?

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.
