In April 1942, a Slovakian Jew named Lale Sokolov was forced into the concentration camps at Auschwitz-Birkenau. When the Nazis learned that he speaks several languages, Lale was put to work as a tattooist where he permanently marked his fellow prisoners. In the next two years, Lale witnesses barbaric  atrocities — but also demonstrated incredible acts of bravery and compassion. Risking his own life, he uses his privileged position to exchange jewels and money stolen by the Nazis to help those who were in prison.
