While the Guardians are going through some changes, Nerissa sends Miranda and Sandpit to Heatherfield to make W.I.T.C.H. miserable.

W.I.T.C.H. gains new knowledge of their sorceress foe Nerissa, a former Guardian and one-time holder of the Heart of Kandrakhar.

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.

It’s Halloween and Irma endures a night of trick-or-treating with Blunk, Lilian and Chris while Will, Taranee, Cornelia and Hay Lin lay a trap for the witch Nerissa.

Will’s fixation on winning at any cost forces her into a devil’s bargain to achieve victory against Nerissa.
