Sarah Williams is a young Welsh immigrant, coming to Utah to join her sister Mary Ann Perkins. When the Perkins are asked to join the San Juan mission to pioneer a trail through Southern Utah, they take Sarah along to help care for the children. But a six-week journey turns into six agonizing months of hard work and toil as the Saints blast their way through a cliff to bring their wagons through what would become the famous Utah landmark "Hole in the Rock."
Finally settled in the San Juan, Sarah's true hardship begins when Ben Perkins asks her to be his second wife. With their faith and testimonies challenged to the core, both Sarah and Mary Ann struggle to find the true meaning of Christ-like love and obedience. Will they make it through?
