Set in the late 1800s, the series follows Abby Walker, an affluent and tough-minded Bostonian whose husband is murdered before her eyes while on their journey out West. After crossing paths with Calian, a curious Apache tracker, Abby arrives in the town of Independence, Texas, where she encounters diverse and eclectic residents running from their pasts, chasing their dreams, and keeping their own secrets, including Kate Carver, an idiosyncratic burlesque dancer with perhaps too keen an interest in Abby's origins, and Kai, a soulful Chinese immigrant who runs a local restaurant/laundry and offers Abby friendship without agenda. Abby also literally runs into Hoyt Rawlins, a slippery rogue, thief, and con artist with a dented heart of gold who quickly eyes Abby as a mark, until she turns the tables on him. In seeking justice for her husband, Abby encounters Independence's noble deputy sheriff, Augustus, and his new boss, Sheriff Tom Davidson, who she has reason to believe is a very bad man indeed. Abby and Hoyt soon find themselves precariously aligned, both seeking to uncover the truth about the identity of Abby's husband's killer, and vow to save Independence – a frontier boomtown where nothing is what it seems.
