This film tells the story of the heroism of Soviet officer Alexander Pechersky. Sobibor was one of four concentration camps in occupied Poland. Prisoners were not separated into two groups like many of the other camps - fit or unfit for work. Those who arrived in Sobibor were doomed for death. With the greatest odds against him, our hero managed to do the impossible - in only three weeks he organised a daring revolt, which aided the mass escape of Sobibor’s condemned prisoners.
