Plot:
A female student named Xiaoman went home to visit her family and never returned. She was found dead after she was found missing. Qianqian, a classmate and best friend, led her teacher and three classmates to travel thousands of miles to Yuanyao Village to collect folk songs and stay overnight. In fact, they were looking for the cause of death of the mute girl Xiaoman and seeking revenge for the truth. Why did Xiaoman, the daughter of the troupe owner, die in the wilderness with a puppet in her arms? And how did her soul get sealed in the puppet after death and make trouble at midnight? Was it suicide or conspiracy? Who will punish the real murderer? Qianqian explored the mystery alone and bravely broke into the haunted house, just to give justice to her best friend.
