In the spring of 1874 missionary Ann Wallace felt called by God to embark on a journey that would take her north along the Natchez Trace traveling among the highwaymen who wait to rob, rape and murder passing travelers. Along the way she becomes stranded in the small town of Trace, Mississippi where she meets the ones who are destined to travel with her. She meets Adam Tara and his two younger brothers and becomes confused about her calling when she falls in love with Adam. She questions her dedication and feels torn between her duty as a missionary and her emotions as a woman.
