The Mangrove Zone of Rio de Janeiro was a well-known area of prostitution that faced several persecutions throughout the 20th century. Between 1954 and 1974, the Mangue Republic was established in the region, a representative regime, which under medical control and police surveillance, women decided who should take over the administration of the houses of prostitution. Based on surviving images, the film proposes another look at this memory of dispute and resistance.
