Jem Cohen raises his meditative gaze to the heavens and tries to show us people who are concerned about things beyond the Earth, in the cosmos, whether little or big, but always far away. We mainly follow an Austrian astronomer named Karl, the missives he shares with a colleague from the academic world, his connections with his wife and grandson, who are in the United States, and his own desire to continue worrying about looking at the stars, finding the darkest possible sky on this planet.
