The Guardians must save Meridian from the evil sorcerer Phobos and Cedric who are searching for Phobos' sister, the long lost princess of Meridian and true heir to the throne. They later find her and the Guardians then set about saving her from Phobos. When Meridian is freed from evil and true heir takes the throne, a new mysterious sorceress named Nerissa frees Phobos' top henchmen and reforms them as the Knights of Vengeance. Once the Guardians learn more about the sorceress and her evil plan of reuniting former Guardians, they are able to defeat the Knights only to have more powerful Knights, in addition to the former Guardians attack them.
In Meridian, Elyon is at the apogee of her powers and excitedly prepares for tomorrowâ€™s Coronation. But Phobos and Cedric talk out of her earshot: thereâ€™s something afoot that Phobos isnâ€™t telling his sister. Meanwhile in Heatherfield, Caleb has finally figured out with the Guardiansâ€™ help a way to get his men across the Meridian Plains unseen. The final battle is about to begin.
Elyon seems to have adjusted to her new life as the Princess of Meridian, living in Phobos' castle, although she is still under the illusion that Phobos has created. Meanwhile, Cornelia gets so upset about losing Elyon to Cedric and Phobos that she quits being the Earth Guardian. Phobos uses this to his advantage and changes the image in the sand to make it look as if Cornelia is getting along just fine with the others and not missing Elyon at all. Phobos sends Meridian Mudslugs after the remaining Guardians and without the Earth Guardian. When they realize that Cornelia is the only one who can defeat them, Will uses the Heart of Kandrakhar to tap into the broadcast frequencies to reach her. Cornelia saves the day by telekinetically levitating the huge mudslug near the portal. She is now officially back in the W.I.T.C.H. group.
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 Phobosâ€™ 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?
In Meridian, the Infinite City occupied by Phobos' guards leaves a thousand rebels with nowhere to hide while Elyon, though shaken by the sight of monstrous Lurdens working in her castle, is still blissfully unaware of whatâ€™s being planned for her Coronation. Caleb and the Guardians have to get close enough to warn her, but how can they without the Heart of Kandrakhar which has been stolen by Jeek the evil Passling?
Will and the rest of the girls try to tell Elyon the truth about Phobos and Meridian, but that becomes very hard when Phobos teaches his sister to make ghostly images of herself to confuse her former friends and the rebels. The real Elyon is upset that she didnâ€™t bring her sketchbook from Earth so Phobos sends Lurdens through a portal to her old bedroom to fetch it. But the creatures also trash a stash of chocolate, the scent from which Blunk is able to follow to Phobosâ€™s and Elyonâ€™s secret Meridian mountain hideout. The Guardians and Caleb search for Elyon under the mountain but are ambushed by Lurdens. Forced into the open, they battle Cedric on the mountainside before returning to Earth, no closer to warning Elyon of the terrible danger sheâ€™s in.

The W.I.T.C.H. girls go on a school skiing trip to show up Swiss exchange-student vamp Sondra, who seems to have mesmerized all the boys at Sheffield. Little do they know that Phobos wants to take advantage of this trip to divide them and separate the other four Guardians from Will and the Heart of Kandrakhar, the only thing that can activate their full powers.
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.
Cornelia’s narcissistic behavior is getting on the other four Guardians’ nerves, especially when she signs them up to help her out at a school carwash so she won’t have to do any actual work.
Elyon is Phobos's sister and the true heir to the throne of Meridian, she just doesn't know it yet. Vathek overhears Phobos and Cedric's plans for capturing her and hurries to tell Caleb only to end up running for his life when Cedric comes to stop him. Vathek and Blunk escape to Earth with Cedric and a worm-looking monster hot on their heels. Vathek relates the news to Caleb who relates the news to the Guardians and they go after Elyon to keep her safe from Cedric's clutches, however, they have to hold off the Larvek from eating Vathek and Elyon slips off in a bad mood after her new beau gives her the heave-ho. She heads back to her place of comfort: Cedric's bookshop.
Phobos uses the knowledge of Caleb's father's being alive to lure him and the Guardians to the Underwater Mines for an ambush. Fortunately, Hay Lin hears the guards whisperings, which allows the group's unimpeded access to the mines. However, the element of surprise is soon lost and the group is on the move. Cedric floods the mine and sends the group plus Caleb's dad on an Indiana Jones-type mine cart ride to the main shaft. Once there, they use the guardroom to float to the surface and come face-to-lizard face with Cedric and a platoon of guards. Cedric tries to go after Caleb and the miners stranded in the remains of the guardroom, but Irma and Hay Lin cool Cedric out with a flash-frozen bubble. Phobos is sitting pretty in his castle, thinking that he has taken care of the major thorns in his side until the girls show up with the last laugh in his looking-glass floor.
Caleb finally attempts to win Cornelia back, but his efforts are complicated by her secret relationship with Peter Cook and the facade she’s maintaining that she is really her own older sister, “Lilian.”
