In a magical realm, three teenage girls—Jade, Opal, and Amber—are chosen to fulfill an ancient prophecy. On the day of their fourteenth birthdays, they set out on a quest that will require them to leave their homes and families and face fierce enemies in a land called Fairytale, where magic reigns and evil is unknown.

Although they meet as strangers, they must learn to trust one another with their lives as they embark on this epic journey, armed only with magical stones.

At the same time, in a parallel world, a young girl named Joa fights for her life in a hospital in Paris. While she is dreaming, she is transported to the magical realm where the three young heroines fight a spectacular battle. Their success or failure will determine the fate of Fairytale and Joa's survival.
