A Spanish marquis and a British housecleaner may appear to have nothing in common, but when Sophie's sister passes away soon after her husband, she leaves her darling daughter, Lydia, to both Sophie and the uninterested Antonio. He has a business to run and estates to live on; what could he share with this "trailer trash"? Sophie loves Lydia like she's her own, but to what extent? Would she get married to Antonio just so she can stay with her niece? Will their love truly be nothing more than being married by arrangement?
