This is the true story of an unsung hero of World War II, Witold Pilecki. A brave officer of the Polish army and member of the Warsaw resistance, who in the fall of 1940, while the Nazis had occupied Poland, voluntarily infiltrated Auschwitz, formed a resistance cell, and drafted reports on Nazi atrocities. For about three years, he endured the nightmare and witnessed the concentration camp turning into a death factory. Yet, when the war ended and the Soviets became the new rulers of his beloved homeland, he was condemned for high treason and executed after a mock trial.
His heroic efforts to inform the Allied forces about the hell of Auschwitz and to pressure them to react were revealed decades later, after the fall of the Soviet Union and the opening of Polish state archives. Witold Pilecki left this world believing he had failed. His voice, clear and optimistic at first, became a whisper in the end, fading away exhausted and disheartened. Yet, his contribution to revealing the truth about the monstrosity of Nazism is now considered invaluable.
