Paul Szczurek served as an SS guard and block leader at Auschwitz, where survivors testified that he became notorious for his extreme brutality. Witnesses described how he beat men, women, and children without provocation, abused prisoners during roll calls, participated in selections for the gas chambers, and took part in executions at Auschwitz. This documentary follows his transformation from a steelworker in Silesia to one of the camp's most feared guards, examines the atrocities committed at Auschwitz, and recounts how survivor testimony at the 1947 Auschwitz Trial led to his conviction and execution for crimes against humanity.
