Gallego, castella 1909. Miguel, a young teacher, is assigned to a small mountain town on the border between Spain and Portugal: Lobosandaus, an inhospitable village with ancient traditions. He is a man of reason, but he cannot control his desires and, as winter approaches, he feels the darkness take over everything around him while his fascination with the enigmatic Dorinda grows. The strange death of a neighbor of the town frees a free spirit in search of a body that allows him to continue with his existence, which will lead Miguel to question the limits between the world of the living and the dead.
