A small poor community called Javé is under threat of being flooded by a new dam that is being built, and the only way to prevent this is to prove the town's historical value. As most of the inhabitants are illiterate, they have no choice but to ask for the help of Antônio Biá, a man who has been ostracized ever since it was discovered that he had sent out letters with lies about their reputations as a way to keep his job in Javé's seldom-used post office. He now has the task of documenting people's memories of how the city was founded, yet each inhabitant has his or her own version of what happened.

Dora, ex-institutrice, gagne sa vie en écrivant des lettres pour les migrants illettrés à la gare centrale de Rio. Ana et son jeune fils Josue font appel à ses services pour retrouver le père de Josue. Lorsque Dora rentre dans son petit appartement de banlieue, elle fait le tri des lettres de la journée, en envoie certaines, jette les autres et en garde une partie dans un tiroir. C'est ce qui arrive à la lettre de Josue. Quand sa mère meurt, renversée par un bus, Josue demande à Dora de l'aider à retrouver son père. D'abord insensible, Dora finit par accepter de l'aider.
