It consists of twenty-six episodes. Unlike the original series, it consists of live-action for scenes on Earth as opposed to 2D hand-drawn animation, but still contains 3D computer animation for Lyoko.

This reboot is also considered the fifth season of the Code Lyoko franchise.

Plot
One year after the events of the fourth season, Jeremie Belpois, Odd Della Robbia, Ulrich Stern, Yumi Ishiyama and Aelita Schaeffer return to their daily lives and routines at Kadic Academy. However, they soon find out that their old virtual archenemy has been successfully reborn with even more strength and power than ever before. The Lyoko Warriors resume their former double lives in order to protect humanity from X.A.N.A.'s evil schemes once again. Joined by William Dunbar, who has finally been accepted as the sixth Lyoko Warrior, and an unreliable girl-genius named Laura Gauthier, the seven heroes are bent on unraveling the reasons for such a return and to exterminate the evil artificial intelligence that is threatening both worlds once and for all.

In addition to X.A.N.A., the Lyoko Warriors discover that they have another dangerous enemy, a mad scientist named Professor Tyron, who seems to be the one responsible for inadvertently returning X.A.N.A. to life. He commands the Ninjas, a group of several virtual human avatars in black and green striped costumes to counter the Lyoko Warriors. In Tyron's lab the group also discovers Aelita's long-lost mother and seek to discover why she is with their newest enemy and how to reunite mother and daughter.

In the cliffhanger it is revealed that Tyron has been married to Anthea for four years, and is now Aelita's legal guardian and stepfather. His only purpose of marrying Anthea was not out of love, but to get his greedy hands on her late husband's archives so that he could effectively create the Cortex region, which then the further evolved X.A.N.A. secretly inhabited to carry out its plans for world domination and destruction once again.

How to Fool X.A.N.A. (Season 1, Episode 9)
Jeremie has an idea: since X.A.N.A. sends spectres to collect Source Codes from inside the Lyoko Warriors, Jeremie plans to dupe X.A.N.A. by injecting one of his friends with false codes which, instead of giving X.A.N.A. strength, weakens it. Only one problem: the procedure is experimental and therefore dangerous. After a small debate about who’s going to get the codes, Ulrich volunteers so that Yumi won’t have to. She is touched by his gesture.

She and Ulrich virtualize on Lyoko. They stop in front of a tower. Ulrich enters and is injected with the fake codes. After a small, strange reaction from the tower and computer terminal, Ulrich springs out of the tower and plays a little joke on Yumi, pretending to be possessed by X.A.N.A.. After devirtualization, the Lyoko Warriors return to Kadic, finally ready to welcome their first spectre.

This part of the plan goes well: a tower is activated. The spectre walks around Kadic. It runs into Sissi, who begins to complain, until the spectre hypnotizes her to remain silent. Sissi then begins to wander around the grounds looking sleepy. Ulrich and Yumi, warned about the spectre by Jeremie, begin to search for it. Seeing Sissi desensitized, Ulrich believes her to be the spectre and approaches her. He realizes his mistake when he discovers Yumi being hypnotized by the spectre. He saves her. Yumi flees, but the spectre doesn't attack Ulrich. It hypnotizes him and sets off after Yumi.

Ulrich calls Jeremie. Jeremie realizes his mistake: X.A.N.A. was spying on them when they injected Ulrich with the codes, so X.A.N.A. knows about the trap.

William and Aelita, who were at the factory, go to Lyoko first. During this time, Odd tries to reconcile with Samantha. After a short time hiding from some monsters, Aelita and William are forced to make a confrontation. Aelita, cornered by three Bloks, eliminates one but is devirtualized by a second. William fights against Bloks and Krabs combined. He performs some great feats and destroys most of them.

He’s then joined by Odd who had to give Samantha a new excuse so he could come to the factory. X.A.N.A.’s guard is ferocious. After a brief exchange about their respective hopeless love lives, William charges and is devirtualized. Odd is the only one who can enter the tower, which is well-guarded. After some great manoeuvers on the Overboard, Odd manages to break past the wall of monsters and enter the tower. But he doesn’t deactivate it because…

On Earth, Yumi finds it difficult to escape the spectre while Ulrich can’t seem to find them. The little game of hide and seek finishes in the gym. Yumi is hypnotized but Ulrich manages to seize the spectre. It absorbs his fake codes and disintegrates.

The fake codes mission is a success but Jeremie decides not to try it again because it's too much for his friends, especially since X.A.N.A. became wary of the tactic. The day is concluded on a positive note while Odd tries once again to patch things up with Samantha.
