But when a woman named Victoria arrives claiming to be their "real" lost daughter, Emily is instantly cast aside. Her parents give Victoria her room, her clothes, and her life. To make matters worse, Emily’s fiancé, Louis, dumps her to be with the new heiress. After a near-fatal car accident, Emily waits in the hospital for her family but they never show up. They are too busy throwing a party for Victoria. In that moment, the "nice girl" Emily dies, and a stronger woman takes her place. When the cold and powerful billionaire Malcolm King offers her a contract marriage to help him clean up his image, Emily sees her chance. He gives her the power to get revenge, and she gives him the wife he needs for business. But as they work together to take down Victoria and Louis, their fake feelings start to become very real.
