WaPo Duisburg

Fresh in the harbor, and already the next corpse is floating by—typical WaPo. Chief of Police Heinrich appears like a shark smelling blood and snatches up the case.

But anyone who knows the WaPo knows that they will investigate anyway. Secretly, unconventionally, with style. No sooner has the WaPo arrived at the port of Duisburg than the next corpse is found floating in the water. But Carsten Heinrich is quicker off the mark and seizes the case. That doesn't stop the WaPo team: they secretly start their own investigation. The dead woman was a crane operator – but who wanted her dead?

Thanks to the support of her father Gerhard Jäger, Nadine has finally found a new apartment. But while they are renovating it together, someone breaks into the empty apartment.

What could the perpetrator have been looking for there? The apartment clearly has a secret, which Gerhard is reluctant to reveal to his colleagues. Nadine's previous tenant is his old acquaintance Wolfgang Brink: a drug smuggler who had to vacate the apartment for a long prison sentence.

Chief Inspector Carsten Heinrich from the Criminal Investigation Department has a date that unfortunately goes badly wrong. After finishing the champagne on his boat all by himself and drunkenly falling asleep, things take an even darker turn. He is awakened in the middle of the night by a scream and witnesses a woman being strangled on a yacht!

While Arda and WaPo boss Kruppka are off to a police conference, Jäger is supposed to be calmly preparing for his exam in maritime English. But there's no peace and quiet to be had.

Shortly afterwards, a currywurst stand on the Rhine is robbed. The perpetrator speeds away with the loot on a jet ski.

A fisherman is reported missing by his wife and shortly afterwards found dead in the Rhine by the WaPo.

The couple had been camping in the nature reserve with a friend. A crime of passion has not been ruled out, especially since the wife insists that her husband had been involved in a heated argument with another fisherman, a sinister-looking man, about the remote fishing spot shortly before his disappearance.

While Arda Turan is training at her old club once again, a young swimmer collapses. Arda saves her, but the young swimmer falls into a coma.

The accident affects Arda deeply. It turns out that the young talent had been pumped full of contaminated steroids. When her alleged dealer is found dead shortly afterwards, suspicion falls on Arda's old coach.

A young couple wanted to spend a romantic night under the stars. But they were robbed...

And then seriously injured while chasing the perpetrator! WaPo chief Kruppka asks her team to take on this case outside of their usual duties.

The supposed flotsam recovered by the WaPo turns out to be a body.

Wrapped in a plastic sheet and tied tightly, the dead man was weighted down and secured to the bottom of the Rhine. The DNA sample taken for identification reveals a surprise: the DNA of the deceased had been secured a few weeks earlier in connection with the murder of a student.
