When Brigham Young summons young Morgan Davis to his office and calls him to join other missionaries in settling the Muddy River Valley (what is now Nevada), Morgan can't imagine what lies in store. He has just two weeks to find a wife and gather enough belongings to help start a settlement.
As Morgan and his new bride, Angeline, travel the long trail south in a covered wagon, they fall in love and connect with the other Saints. But the desert location on the Muddy River soon becomes a physical and emotional test for all of them. Together they face difficult requests from Church leaders, multiple failed attempts to settle, deaths of loved ones, and then perhaps the ultimate challenge—polygamy.
What do stalwart members do when faced with conflicting feelings between what their hearts tell them and the hard instructions from Salt Lake City? Morgan and Angeline are about to find out.
