A small town is terrorized by an axe-wielding madman who attacks small business owners when the moon is full. The movie follows the town's three man law enforcement department, led by Sheriff Jake Genovise, in their attempt to catch the killer before he strikes again. The killer's dark past comes to light via flashbacks. He warns the town of his evil intent by sending letters to the Sheriff detailing his love of killing and his unwillingness to stop. Will the letters lead the Sheriff to the killer? Can the lawmen find him before he kills again or will this once peaceful town remain victimized by a force so evil it may be unstoppable?
