In this exciting blend of action, suspense, and romance set in the Old West, a girl known as Denim Ryder rides into the town of Prosperity with a dark purpose: to exact revenge on the man who years before had betrayed her parents to the Apaches. The man she seeks is Brock Donovan, a powerful and ruthless landowner who has built his empire with the blood of the victims of his ambition.

In the male-dominated town of Prosperity, the independent and free-spirited Denim meets with suspicion and hostility. While single-minded in the pursuit of her own brand of justice, Denim develops an unexpected interest in notorious gunman Ben Straker, whom Brock Donovan has secretly hired to kill the girl. As events turn treacherous, Denim finds support in George Merrell, a former gunslinger-turned-pacifist farmer, and Merrell's loyal friend Luther "Lucky" Grace. Merrell is determined to stay Denim from her deadly course of vengeance...while at the same time coming to realize the depth of his own affection for the girl.

But when Donovan's brutal ranch hands force a showdown, a final confrontation between Denim Ryder and her quarry becomes inevitable—with only one left to survive!
