The small town of Florence, Arizona, is known for one thing - its prison. Gabrielle Hadley is in Florence of personal reasons, though; she's seeking the mother who abandoned her more that two decades ago. In order to support herself and her two-year-old daughter, Gabrielle is working as a prison guard - just about the only job available in this bleak desert town. Randall Tucker is a prisoner at Florence, convicted of murdering his wife. He has one goal: to survive until he can prove his innocence - and reclaim his seven-year-old son, Landon, now living in foster care.
