Four national parks in Brazil, chosen deliberately for landscapes outside the Amazon rainforest itself, anchor this look at the country's protected areas. The film moves between these sanctuaries, showing plant and animal life particular to each one and asking how much tourism and public access a fragile habitat can absorb before conservation loses out. Brazil is presented as a country where biodiversity carries increasing weight in policy and identity, with these parks framed as a last refuge for species and habitats that have nowhere else to go outside their borders. The film stays close to the tension between enjoyment and protection rather than cataloging wildlife for its own sake, treating each park as a case study in that balance. Details on the parks themselves are sparse, so the strength here is the argument about scarcity and stewardship more than a guided tour of any single place.
