We last heard of Joseph chasing after a train in the dark, wet, Warsaw railway yard - did he get aboard safely?
The story then flashed back to the night Joseph's wife was taken by the Nazis. Edek, Joseph's son shot a German soldier in the arm and damaged the truck they were travelling in. In response, the soldiers returned and blew up the house. Ruth, Edek and Bronia escaped across the snow covered rooftops and are now sheltering in the cellar of a bombed building.
What do you think will happen next?
