Years ago, Amos Warren, a prospector, was gunned down out in the desert and Detective Brandon Walker made the arrest in the case. Now, the retired Walker is called in when the alleged killer, John Lassiter, refuses to accept a plea deal that would release him from prison. Lassiter's daughter, Amanda, wants Brandon to find Amos's real killer and clear her father's name.
In Seattle, meanwhile, J. P. Beaumont is at loose ends after the Special Homicide Investigation Team has been unexpectedly and completely disbanded. When Brandon discovers that there are links between Lassiter's case and an unsolved case in Seattle, he comes to Beau for help.
Those two cases suddenly become hot when two young boys from the reservation, one of them with close ties to the Walker family, go missing. Can two seasoned cops, working together, decipher the missing pieces in time to keep them alive?
