Chen Yuan, a young folklorist, returns to his hometown after many years of absence due to the mysterious disappearance of his sister - "Huangliang Township", a village hidden in the mountains that follows ancient customs. In order to find the truth, he was forced to join forces with Uncle Shitou, a village guard who abides by tradition, to investigate a series of real-life mysteries entangled with local legends. Inspired by strange events such as "living corpse marriage", "immortal in the well", and "ghost crying forest", Chen Yuan gradually uncovered the biggest secret of Huangliang Township - an ancient contract about reincarnation, oaths and the balance of nature. In the end, he must make a difficult choice between saving his loved ones and protecting the survival of the entire village.
Chen Yuan (28 years old): A rational and tenacious folklorist. The superficial motivation is to find his missing sister; the deep motivation is to try to understand and heal the spiritual rift between himself, his hometown, and his father by studying strange rumors in the countryside.
Uncle Shitou (65 years old): The village guard of Huangliang Township, mysterious and taciturn. He is a living dictionary of ancient knowledge, and he adheres to the heavy oath to protect the village in his heart, but he is also full of struggles due to the tragedy of the past.
Lin Xiao (26 years old): An urban female painter who followed Chen Yuan to collect works. She symbolizes an outside, purely modern perspective, and her artistry of sensitivity makes her a key figure in unraveling certain visual mysteries.
Chen Xing (20 years old): Chen Yuan's sister, smart and rebellious. Her disappearance was not an accident, but because of her special "birthday and horoscope", she became a key "sacrifice" in an ancient ritual.
