Over a tense day in the emergency hospital, we follow the surgeon's work Evandro and staff in three cases that require risk surgery: a drug dealer, a military police officer and a rich family child, all injured during a shootout in a slum next to the hospital.
Nina is an elderly woman who lives alone and feels distressed by the increasing violence in her neighborhood. Amidst conflicts with her neighbors, she decides to film the movement of drug traffickers from her window, hoping to assist the police. After months of recording suspicious activities, her initiative attracts the attention of a journalist, who approaches Nina and offers to support her in her mission.
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.
