The film starts in the 1940s, during another drought in the sertão, when ranch hand Manuel (Geraldo Del Rey) is fed up with his situation. His boss tries to cheat him of his earnings and Manuel kills him, fleeing with his wife, Rosa (Yoná Magalhães). Now an outlaw, Manuel joins up with a self-proclaimed saint who condones violence (at one point slaughtering a baby) and preaches disturbing doctrines. It is now Rosa who turns to killing and the two are on the move once again. And so it goes, the two running from one allegiance to another, following the words of others as they attempt to find a place in their ruthless land. Blending mysticism, religion, and popular culture in this symbolic and realistic drama, Rocha insists that rather than follow the external and obscure dogmas of culture and religion, man must determine his path by his own voice.
