Deputy Sheriff Carl Houseman returns for the latest instalment in the fast-paced crime series. In a rural part of Nation County, the body of a dead male is discovered in a ditch with one gunshot wound to the head. What appears to be a routine investigation for Carl Houseman and his team turns into a mysterious case, as they learn that there is no way of identifying the dead man: no fingerprint records, no dental records, nothing. This is the cue for an FBI investigator to enter the scene; a new face from the bureau, who suspects it is the body of a Columbian terrorist. Meanwhile, a local meat-packing plant has been accused of passing off contaminated produce. In a town straining under the pressure of mass immigration, the Jewish plant owners suspect foul play. Can there be a connection with the Columbian corpse? Houseman and FBI agent Hester Gorse chase the leads once again in another nail-biting race to discover the truth.
