WaPo Duisburg S04E02 - Die Postkarte

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.
