Josephine Danforth arrives at Miss Sally Pinkerton's Ladies Boarding House and Matchmaking Service in St. Louis with the hope of finding a job out west. When she learns that governesses aren't much in demand on the plains, the eponymous Miss Pinkerton suggests another option: marriage. Reassured by a potential suitor's letters, Josephine reluctantly accepts and heads west. Completely out of her element, Josephine struggles to find her place as the wife of Montana rancher Eb Higginbotham and mother to his orphaned nephew, Clem. With Eb's seeming indifference, Josephine worries she may have made the wrong choice. Is it too late for her to find love?
