The failure of the refrigeration unit of a container in Vienna's Danube port puts Moritz Eisner (Harald Krassnitzer) and his partner Bibi Fellner (Adele Neuhauser) on a hot track. In addition to a lot of chicken feet, three male corpses, still semi-frozen and wrapped in plastic foil, are washed out when the container is opened with the masses of water. They are obviously Asians.
After a walker's dog found a severed hand in a park the next morning, more body parts were soon discovered in garbage cans. The dead man is the Chinese Tsao Kang (Johannes Ahn), who had drunkenly rioted in a Chinese restaurant the night before. With the intercession of Dr. Oskar Welt (Erwin Steinhauer), the chief of the immigration police, he was released shortly after his arrest.
At first glance there seems to be no connection between the bodies found. But in both cases the investigations lead to the meat wholesaler Klaus Müller (Martin Brambach). Suddenly Bibi Fellner's friend gets caught in the crosshairs, the petty crook and brothel owner Inkasso-Heinzi (Simon Schwarz). Because in the Tsao Kang murder case, his fingerprints are found on the murder weapon, a samurai sword. Moritz Eisner is horrified and yells at his partner: "You are friends with a murderer..." It makes him even angrier that the wanted person can free himself with a lightning-fast headbutt and Eisner breaks his nose in the process.
There is additional, massive trouble for Moritz Eisnerhis colleague and supervisor Dr. Oskar Welt, whom he accuses, among other things, of having prevented Tsao Kang from testifying to the police. When the accused made massive threats to him, Moritz Eisner had him arrested.
The chief inspector is worried about Bibi, who has had an alcohol relapse and calls him in desperation. When he brings her home, he finds the fugitive debt collector Heinzi in her apartment, who had hidden here without her knowledge. Without hesitating for a second, Eisner hits - his revenge for the painful headbutt. But a little later, Bibi's friend gives the police an important tip. It is about a company in which, among other things, inferior food is repackaged and renamed and declared as high-quality organic food by predominantly Chinese illegal workers. It is mainly intended for restaurants and generates a high profit. There are many indications of a mysterious connection to the Chinese mafia in this dirty and extremely ruthless business.
When the meat wholesaler found Müller frozen stiff in his company's refrigerated chamber and shortly thereafter Dr. Oskar Welt is murdered, this case threatens to get out of control. Also puzzling is the role of Ms. Gú Bao (Nahoko Fort-Nishigami), who used to be married to the police chief and is the boss of the bar where Tsao Kang smashed a large window pane with an iron bar and attacked guests. With Ms. Gú Bao, many threads seem to come together. But what does she have such an overshadowing fear for?
