Kelly, a young teacher, starts working at a public school on the outskirts of Contagem. Idealistic, she tries to push for a change, but ends up going too far. During a lesson, she gets into an argument with Nicolas, a young student. The quarrel brings some learning: Kelly learns that, on the outskirts of Brazil, the exception is the rule; and Nicolas learns that only by tearing down the present can the future be seen.
