Texas Ranger Samantha Payne takes up a missing person case that has been cold for fifteen years. A boy has been gone all that time, and the evidence she finds suggests he was murdered on a ranch owned by Scott Briggs, a wealthy family man. Scott's estranged son comes home while Payne is investigating, and she grows more certain that the Briggs family had a hand in the boy's death. She is determined to learn what happened to him and will stop at nothing to get the truth, even if the case puts her own life in danger.
