After ten years apart, Boston schoolmarm Jenny McShanahan receives a letter from her beloved father that instructs her to join him in Texas. She has no idea that he's become Famous Sam McShan, the Robin Hood of the West. She arrives to find Sam already gone, but he left instructions for Jenny to hire a guide and rendezvous with him in Nevada.
Texas Ranger Noah Daniel Webster knows Sam personally because his father, Pistol Pete Webber, was Sam's longtime partner in crime. When Pete is killed during their last big score, Noah requests the assignment to bring Sam to justice. Going undercover, he volunteers to act as Jenny's escort across the dangerous prairie, using her to track her outlaw father's location.
As they journey through rough country, love blossoms-but Noah knows the second he arrests Sam, his betrayal will kill Jenny's love for him. Should the lawman do his duty as a Ranger, or should he let love rule? The choice Noah makes will change their lives forever.
