Axe Killian was a Knuckle Dragger, ex-military, now undercover FBI with a Harley, an attitude, and a secret. After an undercover assignment in Montana's vast Yaak wilderness, Axe and his superior, Special Agent in Charge Manny Costa stumble upon a five-year old cold case abduction. Axe is coaxed to accept the assignment with the cooperative assistance of Sheriff Jim Buchanan. However, when Axe closes in on the missing, mixed-blood Blackfeet teenage girl by the name of Peta Ross, his past challenges him to do the right thing. In spite of Axe's extensive training, sense of honor, and call to duty, Peta would not only change who he was but who he would become.
