Kapfenberg in the Austrian Steiermark region, 1957: In the course of a custody battle, Anna Koinegg reports her child’s father, a former member of the Waffen-SS, for having participated in the execution of Jews. The accusation relates to the shooting of 29 Hungarian Jewish forced labourers in Jennersdorf in the early days of 1945, in which he was supposedly involved. But the political mood favours suppression and the charges are brushed under the carpet – until in 1966 the German authorities become involved and the case lands on the desk of former Spanish Civil War activist and detective Hans Landauer. Together the Mannheim lawyers and the disagreeable inspector from Vienna travel to Jennersdorf, to brake the wall of silence and uncover the traces of a massacre that nobody wants to remember...

In late April 1945 hundreds of Jewish forced laborers from Hungary on the death trail heading to Mauthausen end up in a refugee camp in Persenbeug on the Danube. The frontlines both east and west are as close as the end of the war. The Second Republic has already been proclaimed in nearby Vienna and Adolf Hitler is already dead when a motorized SS taskforce covertly attacks the camp and massacres 223 people in a bloodbath. Hardly anybody admits to having seen or heard anything, but inspector Franz Winkler, a Deputy Commander left to his own devices in this remote town, begins to investigate. He risks his head to save his skin. Will he manage to save the nine survivors of the massacre? Manfred Wieninger documents one of the most extraordinary criminal cases in Austrian history while maintaining a fine balance between historical report and fictitious elements. He turns history into a story, in which the victims are no longer nameless.
