A record on Brazilian samba school Estação Primeira de Mangueira's victory on the 2016 carnaval parade. Mangueira's parade that year was a homage to singer Maria Bethânia. The documentary also follows Bethânia on the celebrations of Our Lady of Purification, in Bahia, northeast of Brazil.

From the preparation for Carnival 2020 until the resumption in 2022, including the suspension of parades during the pandemic, the documentary makes a historical inventory from the emergence of samba schools to the present day, showing the cultural strength and its political and social significance.
