Documentary filmmaker David Blaustein focuses on the legacy of Argentina's "dirty war" of 1976-83; during which thousands of citizens; were kidnapped; tortured; and killed by the military government. Their children were taken and scattered into right-wing foster homes. But the persevering grandmothers did not give up; instead marching fearlessly against the authorities in Buenos Aires' Plaza de Mayo. After democracy was restored; they established a comprehensive DNA bank to identify the children. Now; the grandchildren - these "spoils of war" - are being recovered.
