Two hundred years after Cinderella found her prince, the fairy tale is over. Teen girls are now required to appear at the Annual Ball, where the men of the kingdom select wives based on a girl's display of finery. If a suitable match is not found, the girls not chosen are never heard from again. Sophia would much rather marry Erin, her childhood best friend, than parade in front of suitors. Sophia tries to flee the ball, and finds herself hiding in Cinderella's mausoleum. Together with Constance, the last known descendant of Cinderella and her step sisters, Sophia vows to bring down the king once and for all.
