Anna and her two children flee and roam through the woods. At one point, they reach a shelter, filled with hay. They decide to spend the night there. Ben, the youngest child, still seems in shock, and he no longer speaks. At night, he disappears, and in a panick, Anne ventures out to find him. His sister lights handfuls of hay with a lighter, hoping the light will attract her brother. Unfortunately, sparks set the shelter on fire, and the building completely burns down. Ben re-appears the next day. They move on and reach a railroad with some kind of farm building next to it. Although they aren't really welcomed by the occupants, they are tolerated and allowed to stay. A boy tells them that a train sometimes passes there, and they hope to stop that train in order to travel on it to a better place. In the mean while, one man, Koslowski, at leasts tries to uphold some laws and rules there, but people are desperated, cold and impolite. Anne's daughter, Arina, makes friends with a young runaway.
