A new girl teams up with the Lyoko Warriors in the fight against Xana.

It's been some time since X.A.N.A.'s defeat. Now, a new student called Alex Starsky, enrolls at Kadic to get help from the secret protectors of the Earth: the Lyoko Warriors. So little does the group of teen warriors know how hard a war they are about to get into, when they heed to call for help and return to Lyoko to fight a new evil in the form of a human of their age...

Group lived peaceful lives for nearly 3 years but when old friend comes back so does old enemy. But group also gains new unexpected ally which will prove old saying "your biggest enemy is you and you alone" right. But is that new ally will be enough to help Warriors to get rid of XANA for good?

X.A.N.A. nearly destroyed the Core of Lyoko once again. This strains the already strained terms between Odd and Mary even further. Aware of the animosities, X.A.N.A. tightens its pace, causes Mary to get amnesia and increases the stakes again. Can the Lyoko Warriors survive this conflict both against X.A.N.A. and each other as it gets more difficult?
