Arthur is your stereotypical college nerd. He lives with his parents while studying for his MBA and playing Dungeons and Dragons on the weekends with his friends. Everything changes when he helps his longtime friend, Wendy shop for second-hand furniture. Arthur picks up what he thinks would make a good prop spell book, but soon enough learns it's not a prop at all. It's a good thing Arthur doesn't believe in religion, because what he does plans to do to Wendy's sexy roommate, Susan, with his new book of spells would definitely earn him a spot in Hell. Susan is studying to be a nun and has led an extremely sheltered life. Arthur has wanted to bang her for as long as he's known her, and now that he has the power to turn her into his own personal slut, he plans to do just that.
