The Zo'é live deep in the Brazilian Amazon, one of the last isolated peoples on the continent, and this episode of the series Amazonia: Last Call follows the crew documenting one of the first recorded points of contact with them. The footage pushes into stretches of rainforest that had not been filmed before, tracking the Zo'é alongside evidence of the illegal wildlife trade working its way through the same territory. The film sets these scenes against the larger conflict running through the series: logging, poaching, and settlement pressing into forest that still functions as an intact ecosystem, and what happens to a people and a place that have stayed outside that system until now. There is no narration-heavy framing here, mostly observed footage of the tribe and the land they occupy, left to make the case for what is at stake as the Amazon's edges keep moving inward.
