How Long Is “Narradores de Javé”?

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.
