In the immediate aftermath of the Second World War, as the world grapples with the unveiled horrors of the Holocaust, U.S. Army psychiatrist Lt. Col. Douglas Kelley is assigned the extraordinary task of assessing the mental state of Hermann Göring, the notorious former Reichsmarschall and Hitler’s second in command, along with other high- ranking Nazi officials. As the Allies – led by the unyielding chief U.S. prosecutor, Supreme Court Justice Robert H. Jackson alongside Sgt. Howie Triest, David Maxwell-Fyfe, Gustave Gilbert, Col. John Amen, and Burton C. Andrus – navigate the monumental task of creating an unprecedented international tribunal to ensure the Nazi regime answers for its atrocities, Kelley gets to know his “patients.” But he soon finds himself locked in a psychological duel with Göring, whose charisma and cunning reveal a sobering truth: that ordinary men can commit extraordinary evil.
