Three astronomical observatories spread across the globe: Atacama desert (Chile), La Palma Island (Canaries), the Great Karoo (South Africa). In these remote places two kinds of human communities live: the scientists, busy watching and investigating the sky through their telescopes; and the natives whose families have always been there.
The film follows the days and nights both of the astronomers and of the common people. They seem so different but they are also so similar, asking themselves the same questions about life and their place in the universe.
