Seville, the middle of 19th century. Josefina Perrier, a beautiful, intelligent young dreamer of 18, aspires to marry her cousin Maurice Girau, owner of a number of highly prestigious factories in France. Hoping to leave behind the rigid moral code of Seville, in which she feels trapped, Josefina awaits the moment she can leave and drive through the streets of Paris in a carriage or attend its glamorous, high-society parties. However, her life changes forever the evening when she meets Jacobo Fitz-James Stuart, the 15th Duke of Alba. Fifteen years older than her, married with two children, attractive and seductive, they begin one of the most scandalous romances of the era.
