Jess leaves Donger, Texas, and his good friend, John Bodine, to hunt for the ruthless and vicious killer, George Meyer, who was last seen in the town of Chastain.
While there, Jess sees a man bullying a young boy by the man of Johnny, but before Jess reaches them, the 150-pound timber wolf, Shadow, shows up out of nowhere to help.
When Jess continues the hunt for Meyer, Shadow joins in and accompanies him.
Jess wonders if Shadow is just along for the company…or if he knows something that Jess doesn’t.
He soon discovers that to be the case, when he is asked to hunt down three ruthless killers.
