WaPo Duisburg S03E01 - Die letzte Reise

The WaPo investigates a case of domestic violence on a tanker ship. No sooner have Jäger and his team taken care of the frightened Anna Roth than the next emergency call comes in. A dead body has been found on the same tanker—suffocated by volatile gases in the cargo hold. The dead man is, of all people, the domestic tyrant himself, who worked there as the ship's captain. Carsten Heinrich is convinced that it was the wife, but the WaPo is skeptical and secretly investigates on its own. The dead man was involved in criminal activities. Was that why he had to die?
