John Peterson tries to follow the Spirit, but it tells him to preach, and preaching only seems to get him into trouble. His strident defense of the Mormon Church has gotten him fired again, forcing his family to move for the third time in as many years. Looking for a fresh start in Mayfield, John agrees to keep his head down. But when the owner of the local mega church loses his pastor, he invites John to preach without asking the name of his church. After a spiritual prompting, John decides to preach, but as his following explodes, his new-found fame threatens to expose his religion and shatter his family's hopes for a new life.

The town of Mayfield is growing impatient with high school football coach Paul Connelly. The former pastor was hired to help save the football program after the greatest scandal in school history, but after four straight losing seasons, his time is running out. With John Peterson's meteoric rise, the town appears to have found a new moral authority, and an excuse to find a new coach. When Paul discovers that John is a Mormon, he finds the key to restoring his moral standing—all he has to do is expose and destroy John Peterson.
