I Killed Lucio Flavio.

In the early seventies in Rio de Janeiro, detective Mariel Moryscötte de Mattos belonged to a special police force called "The Golden Men". This powerful group of the elite of the police was created with the intention of eliminate crime from Rio de Janeiro, and they had privileges above law to expedite their action against the outlaws. However, absolute power in wrong hands corrupts, and this group formed the "Death Squad", executing criminals without the conventional trial from the justice.
