In Villa Nueva, sad stories seem to be all too common. But Monday is the most anticipated day: Nelson and Gerson arrive with their mobile library, and their stories manage to send the children home happier. The mobile library is a vehicle equipped with books, tables, tents, chairs... but it's much more than that. It's a gateway to the world of storytelling, to fun, to an infinite world full of possibilities. This is the story of Nelson, of the mobile library, and, above all, of all the children who stop to listen to his stories wherever he goes.
