Watch on HDtoday. Every winter, a small town in Castilla-La Mancha called Luzón transforms into a little hell. Its inhabitants, dressed as devils, venture into the darkness and roam its streets with horns, bells, and smeared with soot. Una dança non sancta could have been just an anthropological documentary. Instead, it delves into the inferno with the town’s residents to participate in and immortalize this unholy ritual.
