Brazilian cinema's most popular character since Brazil's Cinematic Revival, returns, now more mature, strategic and isolated, Lieutenant Colonel Nascimento (Wagner Moura) gives Rio de Janeiro's BOPE (Special Police Operations Battalion) both structure and strength. He crushes drug trafficking which had run unchecked in Rio's favelas and stops dirty cops getting payoffs from dealers, only to discover that in Rio de Janeiro's Public Security Office, nothing is as it seems, and that the problem to be faced isn't restricted to drug trafficking. The issues there run much deeper.

Both the city and Nascimento's destinies cross paths in ELITE SQUAD 2 – The Enemy Within. Stemming from intense research, director José Padilha and scriptwriter Bráulio Mantovani put together a current, modern-day story, based on real events that blend in with the fictional story of Nascimento, his family and his friends to talk about the reality of Brazil through cinema.

To meet the challenge and provide the public with a story as engaging as ELITE SQUAD Padilha and producer Marcos Prado put together practically the same crew and cast from the first film, an integrated team that, with great tenacity and dedication, resumed the challenge of continuing a saga and characters that have marked Brazilian cinema forever.

In ELITE SQUAD 2, the system reinvents itself and discovers how to profit without drug trafficking. In pursuit of the route taken by the system, the audience accompanies Nascimento as he goes beyond the boundaries of the barracks, revealing the connections between the militias and the State. And the price of this discovery is high. No one knows where the shots will come from.
