Dara and Marie Durant have been dancers since they can remember. Growing up, they were trained by their glamorous mother, founder of the Durant School of Dance. After their parents' death in a tragic accident nearly a dozen years ago, the sisters began running the school together, along with Charlie, Dara's husband and once their mother's prized student. But when a suspicious accident occurs, just at the onset of the school's annual performance of The Nutcracker-a season of competition, anxiety, and exhilaration-an interloper arrives and threatens their delicate balance.
