Selena and Belle Baldwin, sisters, travel across the plains with their own outfit, in the company of Lon Holiday, captain of fifty, and Josiah Blodgett, captain of ten. Selena's fiance dies at Winter Quarters, and still bitter and sorrowing, she refuses to take an interest in Lon, who has loved her since their first meeting. Belle and Josiah are married immediately after the arrival of the wagon train in the Valley of the Great Salt Lake, and, later, they decide to go to San Bernardino, California, with the saints who plan to settle there. Selena and Lon also are in the company, but are separated for most of the journey after the division of the company. Alfred Quale, who travels with the Blodgetts and Selena, continues an ardent courtship of Selena, who appears to enjoy Alfred.
