For this film master director Patricio Guzmán, famed for his political documentaries travels ten thousand feet above sea level to the driest place on earth, the Atacama Desert, where atop the mountains astronomers from all over the world gather to observe the stars. The sky is so translucent that it allows them to see right to the boundaries of the universe. The Atacama is also a place where the harsh heat of the sun keeps human remains intact: those of Pre-Columbian mummies; nineteenth century explorers and miners; and the remains of political prisoners, "disappeared" by the Chilean army after the military coup of September, 1973. So while astronomers examine the most distant and oldest galaxies, at the foot of the mountains, women, surviving relatives of the disappeared whose bodies were dumped here, search, even after twenty-five years, for the remains of their loved ones, to reclaim their families' histories. Melding the celestial quest of the astronomers and the earthly one of the women, 'Nostalgia For the Light' is a gorgeous, moving, and deeply personal odyssey.
