As produced for The History Channel, this courageous documentary takes an unflinching look at the inner schematics of Adolf Hitler's Third Reich. As the program reminds viewers, the Reich was not only one of the most reviled governments in history, but one of the most dizzyingly complex, with a diabolical totalitarian structure that did much to account for its temporary success. The program travels beyond public comprehension of the Reich, to examine the individuals who comprised it and the secrets that belied it. In the process, it draws heavily from the trove of materials left behind by the Nazis, German newsreel footage, and much more.
