Brazil's toughest cop is out to stop some bad men in blue uniforms in this sequel to Jose Padilha's international hit Tropa de Elite (aka Elite Squad). Capt. Nascimento (Wagner Moura) is the leader of Rio de Janeiro's BOPA Squad, a special police battalion designed to deal with critical situations. When a riot in a prison turns into a standoff between Nascimento and Fraga (Irandhir Santos), a left-wing activist married to Nascimento's ex-wife, things take a turn for the worse and Nascimento's superiors re-evaluate his position with the BOPA. Rather than fire him, Nascimento is transferred to an intelligence gathering team, and he begins compiling evidence against Brazil's top drug lords. However, it turns out that criminals aren't Nascimento's only enemies; Col. Fabio (Milhem Cortaz), a high-ranking member of the military, is also running a drug-trafficking ring on the side, and Nascimento quickly learns just how corrupt Brazil's military and government officials really are. Soon Nascimento and his crew set out to eliminate the bad apples in power with the same ruthlessness they showed the criminals in the private sector. Tropa de Elite: O Inimigo Agora e Outro (aka Elite Squad: The Enemy Within and Elite Squad 2) was an official selection at the 2011 Sundance Film Festival.
