The powerful testimony of Davi Kopenawa, shaman and leader of the Amazonian Yanomami people as he performs the reahu ritual, a shamanistic ceremony mobilizing the community in a collective effort to hold up the sky and prevent it from falling. Through the reahu, the film addresses the destruction of the Yanomami’s way of life caused by the intrusions of the napë, the white prospectors and the so-called civilized world into the Yanomami territory.
