Cynical adventurer Jim Owen will do anything to escape the dark secrets of his troubled past. Betrayed by the woman he loved and scorned by proper society, he agrees to carry out a danger-fraught task: escort Mildred Whimpelhall across a lawless desert to her intended. But Jim is about to learn that "Mildred" isn't exactly what she seems...and the dangers they face together are eclipsed by an even greater peril: falling in love, against all reason, with another guy's bride.
