The film narrates in first person the biography of a street called Aurora. Like any street in the old center of São Paulo, Aurora is a concrete witness of the growing city. Her understanding of the time and life is different from ours, and her ideas and feelings about people change as time goes by. If in his “youth” all she wanted was to become an elegant avenue for the cars to pass, now she misses being a river and feeling infinite. From the ramblings of the street on a rainy day, we are taken to meet a character visiting her history and the history of the city.
