“Here is greatness... wonder... and majesty... no human words can describe!”

In 1858 Lourdes, France, adolescent peasant Bernadette has a vision of "a beautiful lady" in the Massabielle grotto - the townspeople assume this lady to be the Virgin Mary. Pompous government officials think the girl is insane, doing their best to suppress her and her followers, while the church wants nothing to do with the matter. But as Bernadette attracts wider and wider attention, the phenomenon overtakes everyone in the town, ultimately transforming their lives.
