Theodore, the CEO of Cross Enterprises, is a business prodigy at the helm of one of the world's top family-run corporations. After a car accident leaves him unconscious, his family arranges a marriage for him. Cecilia, a country girl raised in poverty, is forced by her stepmother and stepsister to step in as the substitute bride. Theodore and Cecilia strike a deal to be a "marriage of convenience," both using each other to meet their own needs. Everyone expects to see a pathetic joke—a "substitute" wife married to an heir in a wheelchair. But Cecilia not only helps Theodore heal and regain control of Cross Enterprises, she also ensures that her evil stepmother and stepsister lose everything. Just when Theodore's first love reappears, wanting to reclaim him, Cecilia walks away without a second thought. Left heartbroken, Theodore spirals into nightly drunken binges, determined to win her back.
