Official summary
On this particular evening, it’s all too much for Ulrich to bear. He can no more stand living with Odd’s untidyness than he can hearing the song blaring on the radio while he is trying to finish his homework. Ulrich decides to spend the night at Jeremy’s. But Odd, left all by himself, goes into a strange trance-like state and stops moving… The next day, Odd, whose pulse is slowing down more and more, is admitted to hospital… and shortly afterwards, Sissi suffers the same fate. Afraid that this may be a X.A.N.A attack, Jeremy and Ulrich rush to Lyokô, while Yumi, elsewhere, comes to realise that XANA is getting people with the song ! The killer song is being played everywhere and the population is lapsing into a coma. Other cities are starting to be affected, too. Ulrich, Yumi and Jeremy will have to act fast if they want to save Odd, and the greater part of the population from certain demise…

Detailed summary
Odd and Ulrich are in their room: Ulrich in the middle of studying while Odd dances around the place, headphones over his ears, yelling the tune of a new song: “Glad When You’re Bad”. Annoyed by the invasive noise, the working teen goes to Jeremy’s room to study in quiet with help from his friend. Odd continues to dance to the music in the background but he suddenly falls unconscious, eyes wide open...
Ulrich doesn’t return to his room until the next morning and is stunned at Odd’s condition. Panicked, he and Jeremy take him to the infirmary; Yolanda doesn’t beat around the bush: Odd must be taken to the hospital urgently...

Once there, the doctors find that his blood pressure is dropping rapidly... Ulrich feels guilty... Jeremy contacts Aelita and explains their situation. He’s still not certain XANA has anything to do with it: it can’t attack humans directly. But Aelita warns him that there are pulsations in the Mountain Sector... XANA has woken up. Jeremy and Ulrich head for the factory.
At the hospital, more and more people arrive in the same state of unconsciousness as Odd, close to paraplegia. The attack is a violent one...

At the school, Yumi sees Sissi fall unconscious... She is listening to the same music as Odd: “Glad When You’re Bad” and the sound makes the Japanese girl feel dizzy... She’s certain: XANA has created a new song and attacked human beings through their auditory nerves, relaying it to the brain... Fleeing the music XANA is broadcasting on the radio, Yumi joins Jeremy at the factory and explains to him how she discovered the killer music.

Ulrich is already on Lyoko in combat with Bloks. One of the four freezes the teen completely with its special eye. Aelita finds herself alone and flees while waiting for Yumi to arrive...the Japanese girl lands in the middle of the catastrophe in the Mountains and places herself between Aelita and the Bloks. When Ulrich escapes the ice, they defeat the monsters with their combined efforts...

On Earth, XANA infects all the electrical equipment to broadcast its infected sounds. Millions of people are already lying unconscious everywhere...
In the lab, the music begins to play. Caught off-guard, Jeremy tries to disconnect the cables to stop the killer music, but it does nothing, the music keeps playing... In a final effort, the boy enters the codes and parameters for the return to the past, before falling unmoving on the keyboard.
At the hospital, Odd, the first victim, falls further towards cardiac arrest with the goofy smile still on his lips... His electrocardiogram sounds a critical and fatal beep...

The last obstacle on Lyoko, in order to get to the tower, they need to get past a large number of moving rocks. But Aelita, protected by Yumi, manages to get across. She types in the Code at the moment when Odd’s life begins to slip away.
The Return to the Past engulfs a quiet city, an inanimate school, a hospital where many bodies lie numb...

Back to the previous evening, Odd helps Ulrich with his study, abandoning his music player on which he was listening to a song as terrible as “Glad When You’re Bad”: “Under my Cover” by RU Flicknight.

- Attack: Create a popular song and implant soundwaves in it that are harmful to humans: prolonged exposure provokes a drop in heart rate. XANA does everything it can to spread the soundwaves everywhere.
- Virtualisations: Ulrich; Yumi
- Visited Sectors: Forest; Mountain
- Enemies met: Bloks (5)

- Return to the past to save the world from XANA’s deadly music.

- Three Kadic students and Ms Hertz are standing in the hospital when Jeremy goes to talk to Aelita on his laptop, and again when the music takes effect on the whole town. Mr Delmas stated earlier that he can’t allow students to go off the grounds during the day, so they shouldn’t have been there.

Odd: Oh, oh, oh, oh! Oh, I’m glad when you’re so bad! Uh, uh, OH, OHH!
Ulrich: Hey, Odd! If you don’t mind, I’m…trying to study!
Odd: Mm mm mmm mm…YEEEEEEEEEAHHHH!
Ulrich: Cut that out! Maybe you forgot, but we’ve got a test tomorrow! …SO STOP!
Odd: Huh? What’d you say? I can’t hear a thing!
Ulrich: I said I want to study, ODD!
Odd: What’s the sense of you studying? Whatever you do, you’re still going to get a zero in physics! So why not listen to what I downloaded from the web? Go on, listen to it! It sure beats studying! It’s like pure music! And nobody knows who wrote it either! It’s an MP3 file, and it’s free! It’s a pop rock revolution!
Ulrich: You want a revolution? Ok, I’ll give you one!

Odd: Hey, where you goin’?
Ulrich: To Jeremy’s room! At least he knows you need peace and quiet when you’re studying! He’s not like you, selfish!
Odd: Don’t worry, Kiwi, he’ll get over it!

Ulrich: Odd and his music are driving me nuts!
Jeremy: You’re not into heavy metal, pop, funk?
Ulrich: Not when I have to study for an exam!

Ulrich: I didn’t get a lot of sleep.
Jeremy: Really? How come?
Ulrich: Hmph…well I’ll tell you how come! (lovey-dovey voice) Oh, Aelita! Oh, Aelita you’re in my dreams! I can’t wait until-
Jeremy: Shhhh! She’ll hear you!
Ulrich: Between you and Odd, I can’t study or sleep!
Jeremy: Hey, you’re not gonna tell anybody, huh?
Ulrich: Promise, Romeo!

Sissi: I honestly can’t believe how unhip you guys are! You’re a couple of real losers! You ought to go out once in a while!
Nicolas: Well then fill us in, Sissi! What kind of music is it? Is it R&B?
Sissi: R&B?! While not waltz music while you’re at it?!

Jeremy: We can’t let him miss his exam!
Ulrich: Yes we can!

Ulrich: He sang that same song over and over! And look, now he’s fast asleep!
Jeremy: Hey Odd, get up, will you?
Ulrich: If this is a joke, it’s a bad one!

Ulrich (to the ambulance driver): I’m staying with him!
Principal: I’m sorry, Ulrich, but I can’t permit you to leave the school grounds.
Ulrich: I’m staying with Odd!
Principal: Ulrich, get away from that ambulance! That is not the right way to help him!
Ulrich: I don’t care. I can’t let him be taken away like this.

Ulrich (talking to Odd who’s in a coma): Well get you out of this. I swear we will.

Yumi: You’ll never make it all alone!
Ulrich: Who said I would be alone?

Odd: What’s the sense of studying? You’re gonna get a zero!
Ulrich: Ugh, I’ve heard that twice already, that’s enough.
Odd: Hey, listen to what I downloaded from the Web! It’s out of sight! “Under my Cover”! By RU Flicknight! It’s incredible!

Ulrich: And as for you, I wouldn’t say no to your helping me a little. You’re so good in physics!
Odd: That’s right! And if you want help, the reincarnation of Einstein is willing to give a lesson to a sawdust-filled head!

Odd: Actually, it’s pretty mainstream. It’s something that…what I mean is…
Ulrich: It’s the kind of song a machine might’ve written?
Odd: Yeah, that’s right. See, you know a lot about music!
