The W.I.T.C.H. girls (and Elyon) go on a school skiing trip to show up Swiss exchange-student Sondra, who seems to have mesmerized all the boys at Sheffield. And things heat up when Sondra steals Matt from Will, and the two girls compete in a one on one skiing competition. Will tries to "cheat" by skiing in her guardian form (with a coat and hat to cover it up) and Hay Lin flying above her and using her powers to keep Will steady. Little do the young Guardians 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 Kandrakar, the only thing that can activate their full powers. The girls defeat the plan, and find out that Sondra is not a Swiss exchange-student at all, but an ordinary girl who tried to steal all the boys. Plus, the girls (and Elyon) are pleased that Sondra broke her leg. In the B-story, Caleb is trying to tell the girls he knows about fun.
