Jeremy Belpois, an 8th grade prodigy attending boarding school at Kadic Academy, discovers a quantum supercomputer in an abandoned factory near his school. Upon activating it, he discovers a virtual world called Lyoko with an artificially intelligent girl named Aelita trapped inside it. Jeremy learns of X.A.N.A., a fully autonomous, malevolent, and highly intelligent multi-agent system, that also dwells within the Supercomputer. Using Lyoko's powers, X.A.N.A can possess electronics and objects in the real world like a virus to wreak havoc. X.A.N.A.'s primary objective is to eliminate anyone aware of the Supercomputer's existence so that it will be free to conquer the real world and destroy all humanity.
