When Daniel MacLean pins the lone star of a Texas Ranger on his chest, he's looking to avenge the woman he'd planned a life and family with. His pursuit takes him to the border town of Uvalde where he finds a power hungry man hellbent on overrunning the entire territory. As he works to keep the peace along the border, he continues to cross paths with a Mexican woman, Lucia Tarrango, who is trapped in the middle of it all. Will hard riding and straight shooting be enough to settle the score or is he charging headlong into an all out war?

Noah MacLean, one of Mosby's Raiders during the war, has been hired as a Pinkerton detective to track down Emilia Ashley, the daughter of a renowned madam in Philadelphia. Though Noah believes there is something sinister about his client, he does his duty, but can he turn his back on Emily once his job is done?
