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 died 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 decided to go to San Bernardino, California, with the saints who plan to settle there. Selena and Lon also leave with the company for California, but when a division of the company is made, Lon and Selena are separated. Alfred Quale, also on his way to California, begins his courtship of the lovely Selena.
