The old town of Tiwanaku lays a few kilometres south from lake Titicaca: nearby Rufino P"axi Limachi, Waraya-Tiwanaku's priest is talking about his people, the Qullana-Aymara, descendants of the mysterious builders of Tiwanaku. Guardian of an ancient oral tradition aware of the need to preserve and pass on his knowledge, Rufino goes from language to nourishment, from natural medicine to philosophical, religious and scientific issues trying to convince his people to become aware of a cultural heritage based on a community model of life. A model respectful of nature and which has resisted to over five centuries of colonisation and which is jeopardised by the liberal-capitalistic model imposed by a "brain-washed government".
