My Bloody Wedding

Doug, a dorky young mamma's boy, who is about to get married to his beautiful bride, Callista, when he notices a change come over her. He catches her sneaking around at night and lying to him, and she's begun to display flu-like symptoms. So naturally Doug thinks she caught a disease while cheating on him. In reality she has become possessed via an ancient stone and she's been eating his friends and family without him knowing.
