Quem Matou Pacífico? (1977)

Based on the homonymous novel by Maria Alice Barroso. Roberto, Pierre and Pedro are very different men, with very different life paths; but one thing unites them: the three are suspected of having murdered Colonel Pacífico, the rich and powerful owner of the city of Parada de Deus, in the interior of the state of Minas Gerais. However, jail may be the least of his problems, as the colonel's brother is a bloodthirsty gunslinger looking for revenge.
