Once upon a time in Renaissance Italy, Bianca, a young lady from a good family, is of marriage age. Her parents find her a fiancé to their liking: Giovanni, a rich merchant, young and pleasant. The wedding looks set to go smoothly even though Bianca can't hide her disappointment at having to marry a man she knows nothing about. But before the marriage, she learns the secret held and bequeathed by the women of her family for generations: a "man's skin"! By donning it, Bianca becomes "Lorenzo" and enjoys all the attributes of a young man of stunning beauty. She can now visit the world of men incognito and get to know her fiancé in his natural environment. In her male skin, Bianca frees herself from the limits imposed on women. The morals of the Renaissance then act as a mirror to our present time and poses several questions: why should women be treated differently from men? Why should their freedom be the object of contempt and coercion?
