The story begins on September 17, 1999, with heavy rain. An abandoned pavilion located in the back hill of Mushui Town. Fourteen-year-old Hu Jiaojiao was bullied by four men. She saw four pairs of eyes - Wang Jun behind her, Liu Yang watching the wind, classmate Cheng Man hiding in the bushes, and a figure under a red umbrella on the mountain path.
Twenty years later, on the night of the Golden Sunflower Awards ceremony, photos of best-selling author Cheng Man having a fight in a dance hall made headlines. What follows is the truth about the unsolved case twenty years ago - the witness Cheng Man, the instigator Wang Haiping, and the silent accomplice Li Xiangdong. Each person's testimony points to a different "truth."
However, just as the public opinion storm swept across the country, two more shocking cases surfaced: a dismembered female body was found in the back mountain, and the identity of the deceased was unknown; Cheng Man's villa was reduced to ashes in the fire, and the whereabouts of the arsonist were unknown.
Interpol captain He Lan was ordered to do so in danger. What she faced were four narrators with different agendas, four conflicting confessions, and a victim who had disappeared for twenty years. Is he a human or a ghost?
When all the lies were peeled away layer by layer, the final truth made everyone shudder.
