On October 25, 1946, fifty years ago, the so-called Doctors' trial began in Nuremberg. Ernst Klee has compiled extensive material for this film about concentration camp doctors, for example, who nevertheless lectured at universities again after the war or found a place in the executive chairs of pharmaceutical companies. He documents the role of world-famous companies in human experimentation. He was also able to work through the investigation files against Josef Mengele in their entirety for the first time and view unknown material from Auschwitz.

Ethnologist and adventurer, Count Eric von Rosen was a man of contradictions: interested in the natives of Africa and colonial racism. Nestler embarks on a journey in search of his grandfather.
