While scouting locations for a film documentary on Arizona's Apache Wars, private investigator Lena Jones and Oscar-winning director Warren Quinn discover the mutilated body of a young girl. The gruesome manner of the child's death evokes memories of Lena's own rough childhood.

Defying the local law, Lena investigates the child's death and uncovers a small town with a big secret. Founded by the descendants of pioneers who fought Geronimo, Los Perdidos now holds a significant population of documented and undocumented foreign-born residents who live and work at a modern plant. Lena senses a sinister force at work in the town - but where?

When two more girls disappear from Los Perdidos, Lena is tempted to implement some frontier justice of her own to battle a cruel and ancient practice.
