Plot

It portrays a pioneering and risky work carried out in a small Xinane base, by FUNAI, near Parallel 10º South, west of Acre, on the border with Peru. In simple installations, in the middle of the jungle, the sertanista José Carlos Meirelles carries out the difficult mission of protecting the isolated Indians of the region, with the help of anthropologist Terri Aquino. With few resources, specialists perform their tasks tirelessly. In addition to carrying out a permanent negotiation with the riverside populations in the area, they also deal with the confrontation with traffickers and squatters who try to invade it.
