Lower Austria, in the late 1960s. A young man goes fishing at night on the Thaya, a river that bordered on what was then Czechoslovakia. Shots are fired, but the authorities of the socialist neighboring country deny an incident at the border. The man is not coming home. Decades later, his son Max (Harald Windisch), a journalist, revisits the story. At the same time, the body of a 45-year-old Czech named Radok is fished out of the Thaya. An accident? For Moritz Eisner (Harald Krassnitzer) and his colleague Bibi Fellner (Adele Neuhauser), the strange case that saves them from processing boring mountains of files comes at just the right time. While the chief inspector finds out that Radok was murdered, his colleague takes an involuntary bath in the river.
The reporter Max pulls her out of the ice-cold water and initiates the astonished detective into the research about his missing father: At the time of the Prague Spring, the Czechoslovakian secret service lured republic refugees into a trap with a fictitious border. The insidious plan only worked thanks to the cooperation of young Austrians, who played an inglorious role in it. Apparently Radok now wanted to hold the former collaborators accountable. Did he have to die because of that? The latest "Tatort" thriller with Harald Krassnitzer and Adele Neuhauser tells a true story. The incredible story is about perpetrators and victims on both sides of the Iron Curtain and about a family's fatal entanglement in the perfidious power politics of the Cold War.
While solving a complicated crime, Moritz Eisner and Bibi Fellner have to solve a borderline case that can be traced back to the late 1960s. Rupert Henning, known among other things as a screenwriter for the hit movie "Nordwand", makes his convincing "Tatort" debut with this psychologically sensitive crime thriller. It was shot in the beautiful landscape of the Lower Austrian Waldviertel. The ensemble includes Harald Windisch, Hubert Kramar, Thomas Stipsits, Charly Rabanser, Karoline Zeisler and Lukas Resetarits, known from "Kottan determined".
