Princess Lily, the eldest of twelve sisters and heir to a large kingdom, is desperately trying to escape her mother's efforts to find her a mate. Tradition does not allow Lily to be with the one she loves, so she agrees to rule alone rather than marry someone who only wants a crown. Escaping from an obsessive boyfriend, Lily ends up in a secret underground kingdom, where she and her sisters encounter a mysterious prince - magician and falls under a curse that threatens the safety of her family and people. Lily can free them, but the price for freedom is more than she is willing to pay.
