Faca de Dois Gumes

The Brazilian Faca de Dois Gumes stars Paulo Jose as a cuckolded husband. When he can stand no more humiliation, Jose kills both his wife and her lover. It is to be expected that Jose would run afoul of the law for this act of violence. But what Jose never suspected was that the man he killed had criminal connections, meaning that now he's been targeted by the crooks as well. (All Movie Guide)
