The story of one Polish man's efforts to destroy the Nazi camp from within and escape to warn the Allies of the Final Solution before it was too late.
To uncover the fate of the thousands being interned at a mysterious Nazi facility named Auschwitz, Polish resistance fighter Witold Pilecki volunteered for an audacious mission: intentionally get himself sent to the camp and report back his findings. Once inside Pilecki forged an underground army that sabotaged facilities, assassinated Nazis, and amassed evidence revealing the horrifying truth of Germany's plans to exterminate Europe's Jews. But to warn the West before all was lost, he would then have to attempt the impossible: escape from Auschwitz.
