It's been a year since the group first discovered the supercomputer and Aelita, and they decide to throw a surprise party for Aelita. Sissi catches wind of the party and follows Ulrich and Yumi to the factory. On the way there, X.A.N.A. possesses the factory as a whole. Jeremie and Odd are the first to arrive at the factory, finding the elevator to be inoperable. They head off to find the fuse box. Once Ulrich and Yumi arrive there, Sissi confronts them about it. They tell her to leave, but X.A.N.A.'s earlier possession allows him to trap all three in the elevator and drop them to the bottom of the shaft. Sissi and Yumi come out okay, but Ulrich's arm is broken in the fall. Meanwhile, Jeremie and Odd have to deal with the possessed factory equipment. Odd, Yumi, and Jeremie are safe and are at the supercomputer room. While Yumi and Odd are getting virtualized, water from the pipelines inside the walls is falling on the elevator, causing it to overflow. While the elevator is halfway filled, Ulrich promises to Sissi that if they make it out alive, he would be nicer to her. When Ulrich and Sissi are about to drown, Aelita deactivates the tower just in time and the return to the past saves them both. Just like Ulrich promised, he is nicer to Sissi at the end.
