a group of boarding school students who discover a supercomputer housing a virtual world called Lyoko, which they must defend against a rogue AI named X.A.N.A. ​To save both the real world and Lyoko, the group must "virtualize" themselves into the digital realm to fight X.A.N.A.'s monsters and help their virtual friend, Aelita, deactivate towers that X.A.N.A. uses to launch attacks on Earth.
