In this religious horror-story, Father Juan (Fernando Guillen Cuervo) is being interviewed by the Holy Office (Inquisition) in 16th century Spain. He tells a chilling tale of having been born to a woman who has conceived him through the intervention of the devil. However, until the woman was on his deathbed, he was a pretty good priest. It is only when she commends him to her husband, his father, the devil, that he (eventually) gives in to temptation and becomes the focal point for a series of unnatural manifestations (such as snow in the summer) which call attention to his peculiar birth.
