Irma, Taranee, Cornelia and Hay Lin must travel to Meridian after Will is captured by Cedric and Vathek. They cannot transform without Will, who dropped the Heart of Kandrakar in the struggle. The Heart leads them to find its keeper. The girls make their way through Meridian, finding Will's pit-like prison, where she is kept with Caleb and a smelly creature named Blunk. They throw the Heart down to Will and transform to escape the castle. A one-eyed Gargoyle ambushes them at the portal, pulling Irma back, but Will closes the portal on his hand. In the end, Hay Lin names the girls W.I.T.C.H.
