With the intention of finding the purest light and capturing one of the most extraordinary phenomena: the aurora borealis, José Emilio Ramos sets out into the unknown and discovers the most remote places in Alaska, where the nights seem to last forever and the weather conditions for life are extreme. Through the skies of the North Pole, which remain untouched by the light pollution of human civilizations, the Mexican filmmaker and photographer reflects on his role in this universe, in which we are tiny and fleeting, and raises awareness of the natural beauty that surrounds us and that we must preserve at all costs to continue to exist.
