On the run and hiding in the deep forests of the then German occupied Poland and Belorussia (World War II), the four Bielski brothers find the impossible task of foraging for food and weapons for their survival. They live, not only with the fear of discovery, contending with neighboring Soviet partisans and knowing whom to trust but also take the responsibility of looking after a large mass of fleeing Polish Jews from the German war machine. Women, men, children, the elderly and the young alike are all hiding in makeshift homes in the dark, cold and unforgiving forests in the darkest times of German occupied Eastern Europe.
