Daily, thousands of passengers including Bronka and Tchechia arrive at a destination they believe is a resettlement work camp, only to be immediately separated from their families and told to remove their clothing.
Within moments, the masses disappear into a long, fenced passageway down the center of the camp called the tube, except for those indiscriminately chosen out of the lines by the SS.
While ordered to carefully organize the discarded valuables of the passenge.
