Rio de Janeiro, Brazil, is known as the most dangerous city in the world. Gunfights between police and gangsters often occur. Gangsters are rampant, death is commonplace, and even police and gangsters are in collusion, endangering the city. But in this chaotic place, a righteous and strict force emerged. The Special Police Operation Battalion has made gangsters terrified by its bold and fierce handling style. It was 1997, and the Pope was about to come here for inspection. The top leaders asked this elite force led by Nassimon (Wagner Moura) to eliminate the drug chain in the slums in the shortest time. Nassimon, who was tired of the blood and blood, put his mind on his wife and unborn baby. He handed the task to two passionate and idealistic young people-Neto (Caio Junqueira) and Matias (André Ramiro). Both of them are dissatisfied with the corruption in the police force and are determined to make their mark in the elite force... This film won the Golden Bear Award at the 2008 Berlin International Film Festival.
