A fervent believer in Hitler’s theories on race and Aryan superiority, Franz Stangl is an Austrian career policeman who joins the Nazi party and works his way up the ranks. Proving to have a knack for mass murder, he eventually finds himself in charge of three Polish extermination camps where he is responsible for the genocide of 800,000 people. Following a well worn ‘ratline’, Stangl escapes to Brazil after the war where for nearly two decades he leads a comfortable existence in exile.
