The W.I.T.C.H. girls and Elyon go on a school skiing trip to show up Sondra, a Swiss exchange student who seems to have mesmerized all the boys at Sheffield. 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). Hay Lin flies above her and uses her powers to keep Will steady. Unknown to them, 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 girls defeat the plan and find out that Sondra is not a Swiss exchange student at all, but an ordinary girl who tries to steal all the boys. The girls (and Elyon) are pleased when Sondra sprains her ankle. In the B-story, Caleb is trying to show the girls that he can have fun.

Phobos and Cedric start a rumour about the Seal of Phobos to trap Caleb with a sand monster called Sandpit. He tries to find out whether or not there is a spy in the castle. In the B-story, the W.I.T.C.H do a performance at the school, but after discovering Caleb is in danger, they create Astral Drops. After the real girls leave, the Astral Drops ruin the performance.

Prince Phobos sends the Tracker after Caleb in an effort to recapture the rebel leader. Meanwhile, the girls try to go see a movie starring their favorite actor. They struggle to save Caleb and still get to the show on time. In the B-story, Will and Hay Lin's parents won't let them go to the cinema; Will is grounded and Hay Lin's parents are overprotective.
