Layla leads Bloom and Stella back to Lord Darkar's castle with the help of the Specialists. Lord Darkar has captured Layla's friends, the sprightly Pixies, and the Fairies are determined to help them before it's too late. But the underground path is treacherous and filled with monsters.
Faragonda has Tecna stay behind to help monitor the mission at Alfea. Flora and Musa ask why they couldn't come along, and Faragonda shows them by giving the girls a magical simulation of the Under Realm environment.
Flora couldn't use her powers due to lack of living plants, and Musa's powers proved to be too dangerous to use in an enclosed cavern. Before Musa could get crushed by a falling boulder, Faragonda dispels the illusion, then reassures Musa that her powers will be needed in other missions, just not now.
The five are then dropped off at the Under Realm where they try to make their way to Darkar's fortress. Things don't go smoothly as they soon run into some monsters, which they managed to fight off.
Unfortunately, the fight had also caused the girls to lose a huge portion of their magical energies, leaving them drained and vulnerable.
The five come across more monsters, and Brandon falls down a chasm after killing a monster. In desperation, Stella jumps down after him, despite the fact she couldn't transform. Bloom screams in horror as two of their group had fallen into the chasm.

- In the Cinélume version:
- Aisha runs into Knut in the hallway while trying to find Piff. She freaks out at the sight of an ogre in the school.
- Faragonda did not test the girls, as she had already decided to have Bloom, Stella, and Aisha go on the mission for good reason:
- Aisha - She knows the area.
- Stella - She has light magic, which is effective against shadow monsters.
- Bloom - She possesses the Dragon's Flame, which makes her the powerhouse.
- Instead of testing the girls, Faragonda shows Flora and Musa why they cannot go through a realistic, magical representation of the caves. There would be no living plants for Flora to use, making her powers useless. Musa had sound but in the cave her powers could resonate; these vibrations could prove fatal to the group and cause a collapse. Tecna's was not shown or mentioned however.
- Aisha was actually flattered by Brandon after calling her a cutie and asking if she was new to the group.
- In the 4Kids version, Faragonda tested all the girls to see who could go on the mission. Bloom, Stella and Aisha passed, while Flora, Musa and Tecna did not.
- The fairies cannot stay too long in their fairy forms or they transform back, unlike in the previous season where that was not a problem. For example, Stella was is fairy mode the whole trip to Cloud Tower without losing her magic. This is due to Darkar's negative energy which is present in Darkar's Fortress and which absorbs the power of magical creatures and weakens them greatly, preventing them from remaining in the their fairy form for too long since fairies need to use their own magical energy to be able to remain in the fairy form.
- Scenes from this episode, episode 27, 28, 31, 33, 34, 35, 36, 37, 45, 46, 49, 50, 51 and 52 were used for the final Winx club special scene "The Shadow of Phoenix".
- This episode marks the first time that Aisha transforms.
- This is also the first time Bloom's transformation was shown since before she lost her powers in "The Font of Dragon Fire".
- This episode marks the first hearing of the shortened Magic Winx/We Girls are the Winx song.
- In one scene, Aisha's Winx shoes are orange instead of green.
- When Aisha was transforming back to her explorer outfit, her shoes were merged with her Winx outfit even before she changed.
“Now I'd like to point out that some of you will not be taking part in this rescue mission.”
“But we do everything together.”
“Are you okay? Was that something important?”
“Yes! My MAKE-UP KIT!”
“Forget it, just slide down the rope!”
“I have to admit, for once, I miss school!”
“Forget about the clunky flashlights, my scepter is the only way to light up a room.”
“You may be the light of my life, but a good flashlight has saved me more than once.”
