According to Brazilian law, only a few select government workers are allowed to trespass on the land of the Kawahira. They are a tiny community of nomads that live in the Amazon, and they remain uncontacted to the rest of society. They pretty much live in isolation from the rest of the modern world.

The footage was shot by an employee of the Brazilian National Foundation of the Indian (FUNAI), the governmental body charged with preserving the lands and rights of the country's indigenous peoples.

As of 2007, FUNAI reported 67 uncontacted tribes like the Kawahira in the country, 27 of which were discovered between 2005 and 2007.
