A powerful U.S. Senator’s son is murdered in a particularly heinous way, strongly hinting at a revenge killing. Sheriff Zeb Hanks of the Graham County Sheriff’s Office and the San Carlos Apache Police have a long list of suspects who might have wanted to get even with the victim.

Zeb enlists the help of his long-time deputies, Kate Steele and Jake Dablo, to verify alibis on the numerous suspects. Newly hired deputy, Sawyer Black Bear, adds some additional manpower to the case.

High on the list of suspects is Echo Skysong, a recently returned war hero and expert marksman. Zeb can’t even rule out that the senator may have wanted his own son dead. The tangled web thickens as dark moments from Zeb’s past come back to haunt him in the form of FBI Agent Rodriguez who is intent on his own revenge against Zeb. Grappling with his past and the loss of his wife, Zeb and Echo are thrown together by Jimmy Song Bird, Apache medicine man, for an interference clearing. Song Bird hopes to cleanse the spirits of Zeb and Echo through the magic power of peyote.

As the list of suspects narrows, Zeb Hanks and his deputies learn what a powerful motivator revenge can be. The team is drawn to a remote location for a final showdown with the least likely of suspects.
