At the height of the Italian Renaissance, Filippo Lippi is a Carmelite monk at the Convent Santa Margherita, a man equally revered as a great painter and reviled as a rogue. Constantly divided between spiritual and earthly pursuits, it is there behind the cloister walls that he encounters the greatest temptation of his life. Lucrezia Buti is a penniless and beautiful young novitiate, in whose face Lippi finds the inspiration for countless Madonnas. A passionate love develops between the irascible artist and his young muse, resulting in a scandalous romance that threatens to destroy them even as it fuels some of Lippi's greatest work. It will take a miracle of undying faith, unsurpassed beauty, and unfathomable love to save all that Lippi and Lucrezia cherish.
