Friendship is the true magic!
Morgana and the Warrior Fairies are not happy with the Winx's decision to protect the Wizards. To make their feelings clear, Morgana requests the assistance of Aurora, the North Fairy. Aurora uses her powers to summon the beginning of an ice age.
The Fairy of the North comes to Earth, and freezing it over, threatens to send the planet into another Ice Age.
Morgana is displeased that Diana, the Major Fairy of Nature, dropped out of the revenge campaign and for trying to convince her that humans are not entirely terrible beings. Aurora, Fairy of the North, comes to Earth on Morgana's orders, freezing it over and threatens to send the planet into another ice age; they speculate this threat will force the Winx to surrender the Wizards in exchange for the planet's safety. Aurora is then told that no harm can come to Roxy.
The Winx are in the park with the Specialists when the temperature starts to drop. Nebula makes an appearance, stating that if the Wizards of the Black Circle are not turned over to Morgana, then they will have to face Aurora. The glacier has already progressed into the Northern Sea and should the Winx fail to deliver the Wizards to the Earth Fairies, the planet will become another Snowball Earth. Once the message has been deliver, Nebula leaves.
In Sibylla's cave, the Rustic Fairies and Sibylla try their best to heal Duman but it is no use. The ill Duman nearly blows the Wizards' cover by murmuring about the Black Circle being the Earth Fairies doom. The fairies grow suspicious and Anagan plays it off as crazy-talk due to his ill stricken state. The fairies leave them to allow Duman to rest. Ogron is impatient, despising the idea of dancing around their protectors. Gantlos reminds him that being under Sibylla's protection is their best option as Fairy Law states it to be a safe haven. Ogron begrudgingly agrees and they continue to be patient.
In Gardenia, the Winx turn to their newest mission: stop the impending ice age. Sky is ready to go with them but Bloom convinces him that they are the only ones who can defeat Aurora. The guys leave albeit unwillingly to begin their shift at the Frutti Music Bar. Roxy has them take Artu with them due to the danger of this new mission.
The girls return home and informs Faragonda what had happened, in hindsight, hoping to get her orders on how to handle the situation. Faragonda sees right through them and encourages them to follow their heart, in which the Gift of Heart will guide them. Comforted by her words, the girls transforms and teleports to Northern Sea in search for Aurora's palace. Upon reach the Northern Seas, the Winx sees the current state of the open waters and it baffles them. As they continue flying, Roxy telepathically comes into contact with Morgana who ensures her safety and only her. Morgana hopes to sway Roxy to her side.
The Winx arrive at the Ice Tower, Aurora's home and proceed to enter when they encounter angry polar bears and ice creatures guarding the entrance. Roxy uses her powers to change the polar bears allegiance who attack the ice creatures. But those that were not taken down by the bears shoot ice shards at the Winx. The Winx then transform into Lovix form and finish them off; they enter the tower.
Upon entry they being their search but have gotten lost in the ice maze. To make matters worse, more ice creatures and now, the Arctic Fairies attack them. They force the Winx into the center of the ice maze where there is no escape. They are cornered and at this time, Roxy receives another message from Morgana who beckons her to join her, reminding her that she will guarantee her safety and to betray her friends. Roxy realizes something: Morgana deeply cares for her. And so, she uses this to her advantage and warns the Arctic Fairies that if they continue shooting at them she will be harmed. The Arctic Fairies and ice creatures stop. And with that, the Winx use their Lovix together to deal with their opponents and create an opening above them.
Flying through the opening they confront Aurora. Aurora greets them and explains the powerful object she possesses, The Blizzard. It is her power source and according to legend, its power is so great a single drop of its magic can freeze the entire universe. The girls edge closer and Aurora takes a step back, refusing to start a fire-ice battle. She requests that they allow her to leave with the Blizzard and in return she will spare the Planet. Hearing this, the Winx are uncertain what she means until Roxy notices the Arctic Fairies making their escape. Aurora was merely distracting them and she traps them in a room constructed out of ice and snow, and worst of all, Roxy's body temperature slowly starts dropping.
Nebula emerges, laughing as she tells the Winx they will have to consider Morgana's proposition now since their friend is freezing to death.
