Revered Lieutenant-Colonel Roberto Nascimento and his second in command Aspirante Matias are facing tough times within the corrupt political system of Rio de Janeiro. Following the bloody aftermath of a disastrously handled prison riot, Nascimento gets caught in a lethal political dispute that involves not only government officials, but also the deadly paramilitary militias. Combining some stunning action with intense drama Elite Squad: Enemy Within is a worthy sequel to the first film.
