Rebuilding the Circle R abruptly stops when Sherriff Campbell and Addie ride in with the news that Thomas and Anne Marie have been kidnapped by an old enemy, Cain. Shocked and enraged, Rowdy and Roberson set off to find their trail, tracking Cain and the children through the wilderness towards Mexico. With an early winter storm threatening their pursuit, every moment is precious as they race to save the children's lives, but Cain has other plans in mind for Thomas and Anne Marie. Gold and revenge are the only two things that matter, and once he reaches the border there will be little to stop Cain from having both. Forced to ignore pleas for help by a group of stranded settlers, Rowdy must remember that he has only one mission, save the children.
