In the past ten years, forty-seven people have disappeared mysteriously in this small county.
There was no body, no murder, and there were only two words written on the county office record book - not returned.
When the new county magistrate Chen Jingzhi was looking through old papers, he discovered that these missing people seemed to have no connection: some went into the mountains to collect medicine, some went out of the city to do business, and some left home in the middle of the night and were never heard from again.
As old cases were uncovered one by one, more and more people were missing, and bones began to appear. After Xu Xingzhou examined the bones, he said: "This is not an accident." Chen Jingzhi soon discovered the real murderer.
