In the film a popular myth about the Third Reich is presented as fact: The claim that the body fat of prisoners in extermination camps was used to produce soap.
Though evidence does exist of small-scale soap production, possibly experimental, in the camp at Stutthof concentration camp near Danzig/Gdansk, mainstream scholars of the Holocaust consider the idea that the Nazis manufactured soap on an industrial scale to be part of World War II folklore.
A few shots of the concentration camps are combinations of different concentration camps and sometimes do not show the locations suggested.
