The Wizard of Heaven tells the compelling and remarkable story of St. John Marie Baptist Vianney, the humble pastor of Ars, France, who battled with the devil himself, not only for the faith of his parish, but even for that of his country. Starting with the Saint's arrival at Ars, this film brings to life the hardships, indifference, ridicule and opposition he encountered, as well as the zeal with which he strove to overcome them.
