Just west of the Rocky Mountains, a frightened horse with a bloody saddle is found running loose on the Yellowhead highway. Former RCMP investigator Hunter Rayne is on the road in his eighteen-wheeler when he’s flagged down to help calm the horse and find its missing rider.
The horse with the bloody saddle leads Hunter and a good-natured French Canadian cowboy into a complicated murder mystery. The police are none too happy with his interference, but Hunter strongly believes the RCMP has arrested the wrong man and sets out to uncover who stood to gain from the death of a wealthy ranch owner.
His belief in the suspect’s innocence is shared by a rookie female RCMP constable who joins him in the search for the truth. She befriends the dead man’s young fiancé in an effort to get answers, and discovers that the vulnerable Texas beauty is not who the victim’s family believes her to be.
