Q: The movie starts off with archive black-and-white footage of the Nazi's atrocities on the Jews across Europe. The focus shifts to West Belarus, where Nazi SS soldiers, under the command of Bernicki, the Belarussian Police Captain, are busy "sanitizing" a village, killing half the people and abducting the rest. Zus Bielski (Liev Schreiber) and his brother, Asael (Jamie Bell), watch helplessly from the forest. Once the Germans have left, they run to the village and are devastated to find their father dead. They go to their house and find their youngest brother, Aron (George MacKay), cowering under the floorboards in the closet. They take him with them to the forest.In the Lipiczanska Forest, Zus tells a weeping Asael to get a hold of himself. As they sleep, their eldest brother, Tuvia Bielski (Daniel Craig), walks up to them and wakes them up. He first admonishes Asael for not being alert, then embraces him and Aron emotionally. Zus and Tuvia have a rather curt reunion. As they walk into the forest, Zus tells Tuvia that his wife and child are hiding in a village. At night, they discuss their options. The police are after them, however they are safe in the woods. They talk about Bernicki. A friend, Koscik has a gun which they can borrow. Next morning, Aron stumbles across some other Jewish refugees in the forest. He brings them back to his brothers. One of them is a young child, mortally wounded. Unfortunately, they can't save her. As her parents grieve, Zus tells Tuvia that they can't support these people. Tuvia says he'll ask Koscik for food and his pistol.In the nearby village, Konstanty 'Koscik' Kozlowski, their friend and a secret Jew-sympathizer, lets Tuvia inside and gives him food, drink and his pistol, with only 4 bullets. Seeing a police car coming towards the house, Koscik hides Tuvia in the barn, along with some other Jews. It's Bernicki and his sons, who Koscik welcomes warmly. Bernicki talks about his Jew-hunting exploits. Bernicki talks about having killed the Bielskis' father and is now after the sons. He tells Koscik to keep his eyes open and leaves. After they're gone, Koscik gives Tuvia food and drink and asks him to take the Jews from his barn. Tuvia confirms that Bernicki and his sons were responsible for his parent's deaths. He then takes the other Jews and goes into the forest.As they walk into the forest, one of the Jews, an elderly man named Shamon Haretz, Tuvia's old school-teacher, talks to him about his experiences. Tuvia brushes him off. At the campsite, the food is being passed around, with each person taking a small morsel so the others can have some. Zus is upset that Tuvia brought more mouths to feed. Tuvia tells him that it was Bernicki who killed their parents. That night, he goes to Bernicki's house, where he is having dinner with his wife and two sons. Tuvia bursts inside and holds them at gunpoint. He asks them if he knows who he is and why he's there. Terrified, Bernicki says he did as ordered. Tuvia orders him to his knees. Bernicki's sons jump up to their father's aid, but Tuvia shoots them dead. He then shoots Bernicki dead. Bernicki's hysterical wife pleads with Tuvia to kill her as well. Leaving her alive and grief-stricken, he leaves.The next morning, Tuvia tells Zus he killed Bernicki and his sons. They decide to move deeper into the woods. Tuvia brings over more Jews, much to Zus' displeasure. One of them is Isaac Malbin (Mark Feuerstein). The refugees start building makeshift houses in the woods. After almost hitting Zus with a log, Isaac confesses that he's an intellectual, not a carpenter. A refugee introduces Tuvia to his "forest wife". Tuvia congratulates them, a bit unsurely. Just then, two men burst into the scene, one of them holding a rifle, while
