In April 1944 a teenager named Rudolf Vrba was planning a daring and unprecedented escape from Auschwitz. After hiding in a pile of timber planks for three days while 3,000 SS men and their bloodhounds searched for him, Vrba and his fellow escapee Fred Wetzler would eventually cross Nazi-occupied Poland on foot, as penniless fugitives. Their mission: to tell the world the truth of the Final Solution.
