Some young ladies marry for money and social standing, a few lucky ones marry for love, but Tiffany Warren is marrying to end a feud.

Once the Warrens and the Callahans are united by marriage, both clans will stop squabbling over a disputed strip of land. In the chaos of a train robbery Tiffany seizes a golden opportunity: By assuming the identity of her father's new housekeeper she can live with the father she never knew and assess his true character, as well as that of the neighboring cowboy to whom she is betrothed. But, too late, Tiffany discovers that the rivalry between the Warrens and the Callahans has escalated when the Callahans steal the Warrens' housekeeper as soon as she steps off the train! Now, Tiffany, who is pretending to be Jennifer Fleming, finds herself living in the enemy camp, under the same roof as her fiance. All too soon she learns her intended is a handsome, sweet talking charmer whom she has to fight off because he can not keep his eyes, or his hands, off Jennifer. After Tiffany's charade is exposed she refuses to marry Hunter to end the feud. As Hunter goes about claiming his rightful bride-to-be, he knows that although he loves two women, proper, elegant Tiffany as well as spunky, passionate Jennifer, he has only one heart to win.
