Knox Bolling has always resented her beautiful sister, Charlotte, and blames Charlotte for her situation. She's 34, living on her parents' Kentucky horse farm and unable to commit to her boyfriend's repeated marriage proposals. Charlotte, on the other hand, has moved to New York City, where she dabbles in acting and holds a series of dead-end jobs before meeting money manager Bruce Tavert, who, after a brief courtship, proposes. Their intention to start a family, however, proves deadly for Charlotte, who dies in childbirth, leaving Bruce with premature twin boys and providing Knox with an opportunity to explore life outside of Kentucky by coming to New York to help Bruce.
