A Walker origin story prequel with a modern sensibility that follows Abby Walker, an affluent Bostonian whose young husband is murdered before her eyes on their journey out West. Forced to pick up the pieces of her life in what feels like a foreign land - Independence, Texas, 150 years ago - what begins as a lonely quest for vengeance evolves as Abby befriends the diverse, eclectic residents who make up her new hometown. Whether running from their pasts or chasing their dreams, Abby and her new-found family will occasionally struggle with the changing world around them, but more often we’ll find they’re the agents of change. But it’s Abby who’ll reinvent herself the most, as a first-generation Texan in 1870 – though she’ll never forget the face of the outlaw who killed her husband and destroyed her old life.
