With the Storybook of Legends still in Wonderland, Raven attempts to teleport her friends there despite still getting the hand of her powers. Apple, Raven, Briar, Lizzie, Kitty and Maddie end up in Wonderland in just days away from the Queen of Hearts' birthday, but they end up at Wonderland High where they meet the charming Red and White Knights. However the school is ruled by Courtly Jester who attempts to keep the girls from graduating Wonderland High for her devious plans against the Queen of Hearts.

Years ago, Wonderland was cursed by the Evil Queen (from Snow White's tale) and sealed from the outside world. Lizzie Hearts, the heiress to Wonderland's throne, lives in exile as a student of Ever After High. She is surprised to receive an invitation to her mother's birthday, since she can not actually access Wonderland. Madeline Hatter is informed that someone is plotting a coup d'état against the Queen of Hearts, but is unaware of the conspirator's identity. Raven Queen, the daughter of the Evil Queen, is convinced to attempt a teleportation spell, since she is the only one who can safely use her mother's spells. Due to her spell, Lizzie, Raven, and other five female students of Ever After High are transported to Wonderland. But the girls soon realize that they may be trapped in this cursed land.—Dimadick
