Samson Kolechko and his colleague have been dispatched to investigate the illegal sale of meat. How selling cuts of one’s own livestock qualifies as a crime eludes the young investigator, but an order is an order, and, at the insistence of the secret police officer assigned to ‘reinforce’ the Lybid police station, Samson vows to do his very best. But just as Samson is beginning to dig into the very meat of this case, his live-in fiancée Nadezhda is abducted by striking railway workers who object to the census she's carrying out. Complicating matters, the police station has been infiltrated by a mysterious thief, a deadly tram accident—which may have been premeditated—disrupts the city, and, to top it all, the culprit from Samson’s ‘silver bone’ investigation may have resurfaced.
