At the end of the 19th century, a poor family comes to the rural Canudos, a community led by Antônio Conselheiro, seen by many as a holy prophet. Their ways bother the powerful people of the region, and the newly founded Republic sends their army to destroy the settlement, which culminates in one of the bloodiest wars in the history of Brazil.

Three stories of infidelity unfold: a man falls for a married woman, a young girl draws the gaze of her sister’s fiancé, and a husband takes his unfaithful wife hostage after discovering her affair with his best friend.

After a restless night he is awoken by his doorbell insistently ringing. Through the peephole, he sees a stranger. He doesn't know why that man is there but is immediately certain of one thing: he represents a terrible threat. He quickly dresses and manages to sneak away, no doubt in his mind that the stranger is pursuing him, and that the nightmare has only just begun.
