Shadows (1988)

During the Second World War, tens of thousands of blonde, blue-eyed Polish children were snatched from their parents and given to German families. Lebensborn was part of Hitler's plan to expand the Aryan master race within the Third Reich. Eight-year old Jerzy returns home at the end of the war to a joyful reunion with his long-lost mother and grandfather. But problems arise as he is taunted by his peers and, longing for his missing father, burns with resentment for his new communist stepfather.
