Jewelry expert Harriet d'Estino's sister has set her up on a date with a rich Italian, Marco Calvani, the son of a good family friend. She agrees to meet him, so he arrives the next day to tests her abilities as an antiques dealer. He shows her an heirloom from his family, and she appraises the piece, but her critique isn't up to his expectations, so he dismisses her abilities. But everything is business with Marco, and he offers to pay her if she'll agrees to say she's engaged to him and spend time with his mother in Italy. Given the financial stresses her business is under, Harriet agrees and becomes friends with Marco's mom, Lucia. What sort of secrets will Lucia reveal to her about the Calvani family...and about Marco?
