The episode begins with a pan-shot of the Desert Sector, including a stange noise and activated tower. In Odd and Ulrich's room, Kiwi in laying on Odd's bed. The lamp attached to one of the tables starts to shake and the light bulb comes out, followed by X.A.N.A. being careful not to break the bulb, it sets in on the table. Kiwi starts to growl and bark at ghost. The view changes to the hallway outside the room and you hear Kiwi bark a couple more times.
The bell rings and you see the group standing around, waiting for Yumi, who comes to them asking, "Hi, so how did the Italian test go?", to which Jeremie say he doesn't understand Italian, but Odd, being Italian, does, saying, "You're really lame in Italian, Jeremie, old buddy," in Italian. Sissi walks by them with Milly and Tamiya following her asking questions, which annoys her.
The show then goes into the Cafeteria where Odd, Jeremie, and Ulrich are waiting in line, with Aelita and Ulrich already sitting down at the table. Odd and Jeremie are fighting in the line about Kiwi, Jeremie saying how unintelligent Kiwi is, and Odd is sticking up for him.
The picture then changes to show a hallway, with Milly and Tamiya walking down it. They see Kiwi sitting in the hallway and they become worried that Odd will get in trouble with Jim. Tamiya then offers to take Kiwi back to Odd's room, and Milly goes into the Shower room. Tamiya then walks over to Kiwi, the picture shows the eye of X.A.N.A., and Kiwi starts growling and barking at her. While reaching down, Kiwi bites her rist. She gets dizzy and then becomes the first Zombie of the episode. She then attacks Milly in the shower, but Milly overpowers her and gets away.
Back in the cafeteria, the group is still eating their food, well, Odd still is. He says, "So are you going to eat you chocolate pudding?" to which Aelita resonds, "Isn't that your forth one?". Milly then comes running in screaming that Tamiya attacked her, to which Rosa Petitjean, the cook, tries to comfort her, while Jeremie ran a scan for activated Towers on his laptop. When Jeremie finds that a tower is activated, they decide to go to the Factory, and Ulrich calls Yumi and tells her to meet them there. Yumi is shown having dinner at her house with her family when Ulrich calls. Hiroki then bothers Yumi, giving Yumi an excuse to leave the table, saying that shes going to bed. Back at the cafeteria, Rosa starts thinking Milly's serious and tells Sissi to go get her father, to which Ulrich says they'll go with her, which brings a smile to Sissi's face. When they leave the cafeteria, they immidiately see Jim. Sissi tells him that there's a problem with Milly and they find out that he too is a Zombie. Sissi takes off running, away from Jim and the others. Ulrich tries to get Sissi to come back, but when it doesnt work he goes after her, telling the others to meet up at the Factory.

The Zombies walk away from the door and you see William talking on the phone, but whoever he was talking to didn't beleive him about the Zombies, while Jeremie, Odd and Aelita surround the laptop.

When William is completely destracted, they try to get out,but it doesnt work for Herb see them and tells William, who then pushes Jeremie down saying, "Sorry, but it's for your own good. You'll thank me for when we're safe and sound."
Back at the Factory,Yumi makes it down to the Lab, to which she finds no one. The picture then changes back to the school, but to the outside gates. A couple of police officers come. They get the attention of a worker, they ask him if he's seen anything out of the ussual, to which he says he hasn't and the police leave.

When Herb opens the door for Sissi, Jim pushes in and Nicholas tries to throw a chair at him and then William tries to fight him, but it doesn't work for him and he's is thrown outside to the other Zombies. While most of the Zombies are distracted feasting on William fleash and the others on Ulrich, Jeremie and Aelita escape to the Sewer in the Park. The picture then changes to to view them running away from the Zombies that weren't with Ulrich (William is now a Zombie due to being bitten by the rest of the zombie staff), and Yumi pops up and saves them. Back at the Ulrich manages to get in a close to the doors. In the Factory, Jeremie goes into the lab and tells Yumi and Aelita to go to the Scanners.

Another student is overpowerd by the zombified staff and turned into one along with Nicholas. Ulrich, Milly and Sissi are the only ones left. In Lyoko, the third Crab starts to chase them. Yumi then desides to stay behind and fight the Crab while Aelita goes to the tower. She then destroys the Crab by jumping on it back and uses her fan. She then ketches up to Aelita. When they get out of the maze, they run into another problem, the ground and the tower has dissappeared. Then Jeremie tells them that its still there and he can see it on the screen, and Aelita uses on of her powers and see the tower.

In the Factory, Jeremie hasn't realized yet that the Zombies are in the lab, he does though when Kiwi bites his ankle.
Back in the cafetiria,things aren't going good the students that were bitten by the zombies turned into one themselves and Ulrich is attacked by the zombified Odd while the zombies are now surrounding them and nearly turning Sissi and Milly into zombies. Aelita then deactivates the tower and the Zombie version of Jeremie uses the return to the past, and time goes back to when their standing waiting for Yumi to join them. When Sissi walks away, Ulrich and Aelita start to complement Sissi which confuses Milly.
And the episode ends with Jeremie saying, "Yeah, in fact you never can guess a persons true colors, can you?" with the others nodding.
- Chronologically, this episode takes place after Temptation and A Bad Turn, however it was aired weeks before either.
- The original French name for this episode is Contagion.
- When Milly makes the statement "Hey Sissi, what do you think of your father's idea to make a language exchange program with France?" it supports the idea that this show does not take place in France for the English version. This was a change to make sense to a USA/England audience, as there are few clues besides the opening & closing credits to elude to it being a French show when translated.
- In its original French, Milly says "Sisi, Que penses-tu de la décision de ton père d'organiser des échanges languistiques avec l'Angleterre?" , which basically translates to "Sissi, what do you think about your father's decision to organize a language exchange program with England?"
- The episode might be a homage to the 1981 horror film, The Evil Dead, and the Living Dead films, primarly the first film Night of the Living Dead.
- This episode marks the first appearance of the Grut Advertisement.
