Devil's Canyon

Abby (Virginia Mayo) runs with a brutal group of robbers in the Arizona Territory, but when she learns that members of her gang are targeting Billy (Dale Robertson), an old acquaintance, she tips him off. Billy kills the would-be assailants and is sent to prison, where he is incarcerated with Jessie (Stephen McNally), who is both the brother of the men Billy killed and Abby's lover. When Abby also gets locked up, her allegiance to the two rivals makes for an explosive situation.
