Steadfast Genesis and defiant Isaiah are content on their famed grandfather's ranch nestled against the Rocky Mountains. When a mysterious new preacher arrives, called Leader by his congregation, the foundation of their legacy is shaken. Their pious mother, wooed by Leader's commanding presence becomes a devout member of his fold, pulling the sisters into Leader's reach. While the Depression puts pressure on the ranch, Leader's prosperity only grows. But his "church" is more than it appears. Once Genesis discovers his true intentions, she must fight to keep her ranch, and her sister, out of Leader's grasp.
