During work on the orange subway line in the Bixiga neighborhood, in the city of São Paulo, archaeological sites were found with great potential to reveal more evidence about the black presence in this region. Mainly, due to the fact that this occupation is repeatedly erased to the detriment of the memories that emphasize the Italian community that also started to live in the neighborhood from the last years of the 19th century. The documentary seeks to understand what is at stake with the subway works and what challenges the neighborhood will face in the coming years.
