In August 1942, 270 people of Jewish nationality went on a mortal campaign. Only at night they walked through the territory occupied by the Nazis. In two months they covered 1,500 kilometers. 218 reached their cherished goal. They followed one man: partisan Nikolai Kiselev, a native of Bashkortostan. Survivors in this campaign settled mainly in Israel and in America. Their descendants, which number about 2,000 people, are scattered around the world. We managed to talk with several participants in the campaign and make the film "Never Again."
