Maior Que o Ódio (1951)

Two friends grow together in the same neighborhood but, as adults, take different paths in life. One becomes an honest worker, and the other gets strayed. But the good guy's sister has an affair with her brother's friend, and is much abused by him. Her brother wants revenge. But when he sees him in danger, some time later, he must decide which is the stronger feeling: the former friendship, or his wish for revenge.
