Renaissance Italy is a world of riches open to any man who dares to conquer it. In the life of young Lisa the doors to this world remain closed. Promised in her youth to a widower as a loving wife and mother, she is resigned to an unremarkable existence clinging only to the memory of being "Lovely Lisa" to the now great Leonardo Da Vinci. But when their paths cross again her portrait will become his masterpiece and her smile will capture the imagination of the world.
