In an ancient town in southern Hunan, a filial doctor who had never visited his father's grave went home to do so, and met a girl who died unjustly. He asked Tang Yangjun to avenge his grievances, and gave him a magical package. In the end, he was chased by evil spirits who wanted to take back the package, which triggered a series of supernatural stories. In order to protect the evidence, Tang Yangjun was chased by these evil spirits with no way out, so he had to take his wife and son with him overnight. He ran away without any purpose and fled to a mysterious ancient town, where he practiced medicine and finally met a master in a deep mountain. Looking for an opportunity, he returned to modern times and struggled with the evil spirit. The evil spirit was cruel, cold and ruthless by nature, committed great crimes and committed evil, and released countless evil spirits to harm the world. One after another, magical and supernatural tragedies occurred in the ancient town of southern Hunan.
