A remarkable documentary from Chile which juxtaposes three different threads of the country’s history - pre-Columbian shepherds, the struggle of people exposing the brutality of the Pinochet regime, and astronomy in the Atacama desert. Each of the stories has a haunting tone and each presented with the kind of passion for the material and search for truth you’ll find in a Herzog or Errol Morris documentary. In addition, the interwoven stories are beautifully shot by Patricio Guzmán, who also also directed the excellent Allende documentary from 2004.
