Siegfried Graetschus was an SS officer who served in some of Nazi Germany's deadliest killing centers. After taking part in the T4 Euthanasia Program, he was deployed to Belzec, Treblinka, and finally Sobibor, where he became commander of the Trawniki guards. He helped oversee the systematic murder of hundreds of thousands of Jewish victims during Operation Reinhard, one of the largest extermination campaigns of the Holocaust.

On 14 October 1943, Jewish prisoners led by Alexander Pechersky launched the famous Sobibor uprising. As part of the carefully planned revolt, Graetschus was lured into a tailor's workshop and killed with an axe by resistance fighters Arkady Wajspapir and Yehuda Lerner. His death became one of the key moments of the only successful large-scale prisoner revolt at a Nazi extermination camp.

This documentary explores Graetschus's role in the Nazi extermination system, the operation of Belzec, Treblinka, and Sobibor, and the extraordinary courage of the prisoners who fought back against impossible odds.
