Polizeiruf 110 is a long-running German language detective television series. The first episode was broadcast 27 June 1971 in the German Democratic Republic, and after the dissolution of Fernsehen der DDR the series was picked up by ARD. It was originally created as a counterpart to the West German series Tatort, and quickly became a public favorite.

Kerstin floats stoically across the Mecklenburg Lake District in her red GDR kayak. Aimlessly, between tourism and dreariness, she glides over the water for days, striving to remain alone. The many rivers and lakes are familiar to her. But where does Kerstin come from? What is she fleeing from? Who is pursuing her? The evenness of this journey breaks when Alima appears, finally asking the paddling loner the right questions.
