Dangerous Beauty

Dangerous Beauty is a movie starring Catherine McCormack, Rufus Sewell, and Oliver Platt. A Venetian courtesan becomes a hero to her city, but later becomes the target of an inquisition by the Church for witchcraft.
Veronica is brilliant, gifted and beautiful, but the handsome aristocrat she loves, Marco Venier, cannot marry her because she is penniless and of questionable family. So Veronica's mother, Paola, teaches her to become a courtesan, one of the exotic companions favored by the richest and most powerful Venetian men. Veronica courageously uses her charms to change destiny -- and to give herself a chance at true love.
