The Uru-Eu-Wau-Wau people have, for centuries, lived deep in the Amazon rainforest of Brazil.

First contact with the Brazilian state came in 1981, and it came with a great cost: disease and illness killed off half the tribe.

Their territory is meant to be protected, but instead they’re facing invasion, with settlers moving into the forest and claiming the land as their own, with chainsaws and with fire.

A new documentary, The Territory, filmed in part by the Uru-Eu-Wau-Wau themselves, captures the struggle between the two groups.
