The unlikely police pair Verena Berthold and Otto Garber are part of a special task force investigating organized crime in Berlin. He comes from the east, she from the west of Berlin. He's a redneck, she's from a better background. This causes conflict. Over time, things start to sizzle between the two. Their team includes the agile German-Turkish Yücsel and the sluggish Georg, who, like Verena and Otto, are constantly bickering. The department manager is Lothar Reddemann. Sputnik is a former colleague of Otto's from the People's Police and is constantly coming up with new business ideas for stores and pubs where the team meets.

The three friends Ertan, Kemal and Mehdi live in Kiel. They are foreigners, "Kanaks", as they proudly call themselves. For them, this term is an expression of their attitude to life. The trio keeps their heads above water with small-time crooks, but over time they are drawn deeper and deeper into a maelstrom of violence and crime. On a whim, Erkan acts as the protector of two prostitutes and makes enemies of two unscrupulous pimps. After a failed robbery, Ertan ends up in prison for a short time and Kemal is deported to Turkey. However, the two proud "Kanaks" don't let this get them down, on the contrary: together, the friends now want to build a drug air bridge between Istanbul and Germany. But the dream of quick money ends in death and grief for Kemal and Ertan.
