Nympha (2007)

NyMpha is the story of Sarah (Tiffany Shepis), a young American girl, who goes to Italy to take vows needed to become a cloister nun of the "New Order" Convent. The rules of the convent are very strict, so strict that they are often considered a form of torture. Sarah's path is divided into four steps, "hear" the Lord, "see" the Lord, "touch" the Lord and "talk" with the Lord... Each step will be painful for both Sarah's physical and mental self. Moreover, during Sarah's journey, she often has visions of the Convents past, visions that it was the house of a young girl named Ninfa... Ninfa's life was ruined by the religious fanaticism of her violent grandfather Geremia, who believes that he can talk directly with God. In reality, he is utterly mad, and this madness seems to be present today (within the walls of the convent) where young Sarah lives...
