Story :The film accompanies the investigation of the historian Sidney Aguilar after the discovery of bricks marked with Nazi swastikas in the interior of São Paulo. They then discover a horrifying fact that during the 1930s, fifty black and mullato boys were taken from an orphanage in Rio de Janeiro to the farm where the bricks were found. There they were identified by numbers and were submitted to slave labour by a family that was part of the political and economic elite of the country and who did not hide their Nazi sympathizing ideals.
