Inhabiting a shrinking pocket of rainforest in Paraguay’s Eastern Canindeyu Region, the Ache are one of South America’s last hunter-gatherer societies—and in imminent danger of cultural extinction. This program presents an intimate portrait of the Ache in their natural habitat, focusing on the Gatu tribal group. Sequences filmed during extensive stays with the tribe reveal their customs and technology, including hunting tools and methods, camp preparations, forays into agriculture and commerce, and a spiritual connection with jungle wildlife. Interviews with anthropologists and political advocates help illuminate the tribe’s struggle against rapid development and roving campesinos. (49 minutes)
