In Rio de Janeiro, people from the Mangueira neighborhood follow the television broadcast on a big screen as the juries vote on each samba school. In 2019, Mangueira took to the Sambadrome a strong, bold samba dedicated to those excluded of the official history: poor people, natives, black persons and women. The Samba school honored Mareille Franco, a political activist of Rio de Janeiro as a symbol of the fight of Brazilian black women against racism and police violence, which was murdered in 2018. The film witnesses the tension while waiting for the final score, and the great joy of people from every generation when Mangueira wins and becomes champion of the Carnival.
