This documentary begins with the Nuremberg trials of the immediate postwar era and ends with the present-day dismantling of Nazi war crimes units throughout the world. Major cases and manhunts are reconstructed and analyzed. The narrative is supported with interviews, location sequences, newsreel footage and intelligence material, much of it never before seen, from the Central Intelligence Agency, the US Justice Department, the German War Crime Archive, and the Russian Interior Ministry. The principal subjects include professional and amateur investigators, assassins, ex-partisans, military officials, jurists, and politicians. The film also features interviews and confrontations with war criminals. In the interest of objectivity, the film does not shy away from disclosing the investigators' faults, miscalculations, and failures. It also includes personal notes with the investigators appraising their own legacies.
