Hjalmar Schacht stabilized Germany's currency after the hyperinflation of the 1920s, then, as Hitler's economics minister and Reichsbank president, engineered the MEFO bills, a secret financing device that let Germany rearm massively while dodging the Treaty of Versailles on paper. The film traces how a man credited with rescuing the German economy became indispensable to the Nazi war machine, using archival photographs, period footage, and historian interviews to lay out the mechanics of his financial schemes alongside his growing unease with the regime he had helped fund. It follows his break with Hitler, his arrest and imprisonment after the July 20, 1944 plot against Hitler's life, and his survival of the war in a concentration camp. The final section covers his trial at Nuremberg, where prosecutors and judges disagreed sharply over whether financing rearmament made him a war criminal, and his controversial acquittal. The result is a portrait of expertise placed in service of atrocity, and of how postwar justice struggled to categorize a man who built the tools without pulling the trigger.
