The first season of the show has very little plot development. The only major plot developments are made in the two-part finale. The rest of the episodes are mostly filler. Until the finale, each episode consists of the group discovering an attack, stopping the attack, and resetting time to cover it up. Other subplots are included, such as their relationships with one another and other students and teachers at the school. Usually the interaction with their classmates and teachers early in each episode contributes to Xana's attack. Throughout these events, Jeremy works on a program to materialize Aelita in order to shut down the supercomputer safely. He eventually completes the program in the two-part finale, but Xana takes measures to keep Aelita linked to the supercomputer, preventing the group from shutting it down without killing her in the process, leaving a cliffhanger opening for the second season.
