In 2019, the Brazilian government coordinates the largest and riskiest expedition of the last decades into the Amazon rainforest to search for a group of isolated indigenous people in vulnerability and promote their first contact with non-indigenous. Bruno Pereira, who would later be murdered in the same region and turned into an international symbol in favor of the indigenous and the forest, leads the expedition.

The last two surviving members of the Piripkura people, a nomadic tribe in the Mato Grosso region of Brazil, struggle to maintain their indigenous way of life amidst the region's massive deforestation. Living deep in the rainforest, Pakyî and Tamandua live off the land relying on a machete, an ax, and a torch lit in 1998.
