Empty Boxcars tells the amazing story of the survival of over 50000 Jews in World War II and the mass murder of 11393 Jews from territories under Bulgarian control in Greece and Macedonia. The plot to murder all European Jews was marked 'top secret' but was brazenly public. Footage of the trains renders the crime visible. When the plot is exposed, Bulgarians from many walks of life, church leaders and labor leaders, lawyers and doctors, rose up in protest. Would we risk our lives to save someone in deep trouble? These courageous Bulgarians encourages us to think we must, and so we can.
