Operation Valkyrie tells the astonishing true story of a bold German plot to assassinate Adolf Hitler - and the man who risked everything to make it happen. Sebastian Kock (The Lives of Others) stars as Claus von Stauddenberg, a once-idealistic German army colonel whose exposure to wartime atrocities and personal battle injuries move him to conspire to eliminate the power-crazed. The heroic tale remains a fascinating, must-see example of the German resistance to Hitler’s oppression.
