A murder case occurred in the patrol room of the provincial capital. Lu Xingzhou took the blame for someone else and was sent to "Chenghe", a small county in the south of the Yangtze River, where he became an unpopular criminal assistant in the county department.
He doesn't believe in ghosts and gods, he only believes in the flaws in the medical records, time, footprints and confessions.
But Chenghe loves "hauntings" the most: Lantern lamps on the river asking for life, paper man substitutes coming to the door, drawing evil lots in the ancestral hall will lead to death, white shadows on the stage strangling the throat, children screaming for injustice under the well... The more people spread the truth, the more reliable the murderer becomes.
Lu Xingzhou peeled back each "ghost case" into a human case - institutions, drugs, illusions, greed, and old grudges, layer by layer. The case was solved and hatred was forged.
