After another successful battle against X. A. N. A. and another return trip, Ulrich, Odd, and Yumi are nowhere to be found. They, however, do not see anything wrong with where they are. X. A. N. A. has trapped them in a world of its own design, which is fashioned after the school to ease their suspicions. Meanwhile, in the real world, Jeremie is being questioned on the group's disappearance. However, the world that Ulrich, Odd, and Yumi are in appears to have some glitches in it. Jeremie finds that this world can be accessed through the scanners, and after a near-death with X. A. N. A.'s virtual zombies, Aelita manages to save them.
