In the poverty-stricken favelas of Rio de Janeiro in the 1970s, two young men choose different paths. Rocket is a budding photographer who documents the increasing drug-related violence of his neighborhood, while José “Zé” Pequeno is an ambitious drug dealer diving into a dangerous life of crime.

In 1997, before the visit of the pope to Rio de Janeiro, Captain Nascimento from BOPE (Special Police Operations Battalion) is assigned to eliminate the risks of the drug dealers in a dangerous slum nearby where the pope intends to be lodged.
