Maynard Jacobs and his friends search for adventure leads them to a remote mountain cabin, where they spend the summer prospecting for gold in the historic Arizona gold fields. The events of the summer lead to conflict and treachery, and in the end, they go their separate ways. Years later his grandchildren experience tumultuous change and retreat to their grandfather's ranch. Here they explore the mountain where their Papa and his friends sought a fortune in gold, long before they were born. And here they learn of the faith that sustained their beloved Nana and Papa. When villains from the past reappear, the children are separated from their grandfather and forced to flee alone on horseback. In the harsh Arizona wilderness, the children must survive by their own courage and faith, and their eyes open to see the miraculous in the ordinary.
