Bloom becomes involved in a fight between a magical fairy Stella, and a gang of trolls headed by Knut the Ogre. Stella introduces Bloom to the world of Magix, where the College of Alfea for aspiring fairies is located.
Bloom and Stella arrive at Alfea and meet Flora, Musa and Tecna. They form a club named "Winx" and have their first encounter with the witches of Cloud Tower.
It's the beginning of the school year and Alfea and Red Fountain will be having a school dance, and all the girls are excited. Stella, Musa, Flora, and Tecna all have dresses to wear, but Bloom is desperate when Icy, Darcy, and Stormy come in to sabotage the Dance! What will Bloom do with her Winx?
The Winx girls and the Red Fountain guys have a cleaning party as a "punishment" for going to Cloud Tower. When the witches conjure up a minotaur to take them down, the party ends up being crashed.
The mysterious voice that saved Bloom at Cloud Tower continues to torment her in her dreams. Finally, the voice discloses its face - Daphne, one of the nine legendary nymphs of Magix.
Bloom, Stella, Sky and Brandon try to enter Cloud Tower in order to find Bloom's powers. Riven regrets his behavior and rejoins the fairies' group to help save Magix.
The Trix are all set for a final battle against Alfea as they rally their greatest army yet. Bloom has a heart to heart talk with Daphne. Will it help get her powers back?
