Police novel centered around the buried body of a child found in the steppe by Mongolian nomads. Police chief Geroulndelger awakens the nightmare of the murder of his own child, which was never solved.

Gradually, the connection between the two murders and their correspondence with other equally brutal cases will force him to confront the terrible truth. In Mongolia, graves are not only horrific. For some, the precious smuggling of "rare earths" is worth more than the lives of many people, both innocent and not.
