Washington, D.C. Premiere In Chile, astronomers from all over the world gather in the desert of Atacama at an altitude of 3,000 meters to observe the stars. The desert sky, without a trace of humidity, is so translucent that it allows them to see right to the boundaries of the universe. This peculiar arid terrain is so rich in salt that it mummifies bodies, pre-Columbian Indians as well as victims of Augusto Pinochet’s repressive 17-year rule. While the astronomers examine the most distant galaxies in search of possible extraterrestrial life, at the foot of the observatories, a group of women are digging through the desert soil in search of their missing relatives.
