A gifted surgeon, Galen Hall, walked away from the horrors of the Civil War when an orphanage was shelled three days after Lee surrendered to Grant. Ten years later, a young boy is kidnapped from St. Louis and held for ransom. Wade Phelps, a Pinkerton agent, discovers that the child has been brought to Texas and Phelps seeks out Galen to ask for his help recovering the child.

Dutiful daughter Eleanor Trent lives in St. Louis with her father, and she is appalled when he arranges a marriage for Nora to a man she hardly knows. Although she objects, Nora doesn't think it's her place to go against her father wishes. However, after being abandoned by her husband the day after the marriage, Nora discovers that her new husband and her father have used her for reasons that are a complete mystery to her.

Rebelling against her father, Nora travels to Texas to find her missing husband. Once she is in Texas, she meets Galen Hall when she's forcibly taken from her stagecoach. Suspecting that Nora is somehow involved in the child's kidnapping in St. Louis, Galen rescues Nora from the outlaws. Despite their animosity toward one another, they form an uneasy alliance and together they set out to find and save the missing boy before he is sold to the dreaded Comancheros and disappears forever.
