Every student in Sheffield Institute is getting his midterms back and everybody is just about happy with his grades, except Taranee. Cedric's disguise as a bookseller seems to have attracted Cornelia, Elyon, Irma, Taranee, and Hay Lin to the store to look for history books (and to ogle at Cedric). While in the bookstore, the W.I.T.C.H. girls inadvertently touch an inversion point and find themselves in the middle of a Labyrinth inside Phobos’ castle. Will they be able to find their way back without powers and without help from their leader Will who is at home buried in school work?

Elyon misses her parents and Phobos agrees to let them visit Elyon. However, when the guardians find out that Elyon's parents are held captive in the Cavigor prison, they go in and try to bust them out. But the task is easier said than done when Elyon's parents have been hypnotized, with the addition of hundreds of guard led by Cedric chasing them and the task of freeing hundred of prisoners. In the end, they free everybody including Elyon's parents, which makes Elyon worry about what the rebels will do to them.
