Ten years ago Vernon Oxford turned his back on the bright lights of Nashville and a life as a popular country singer, and gave himself to the Lord. Today, he is a gospel preacher in Franklin, Tennessee, but his congregation extends beyond his own community in the southern states of America. He takes his mission to his spiritual cousins in Northern Ireland, who share the same fundamentalist Protestant beliefs. Tonight's film follows Oxford from Nashville to Belfast as he pursues his healing mission through the houses of God and of the Devil.
