Samantha Suarez - Odd's former sweetheart and girlfriend - enrolls at Kadic, and the boy eagerly pursues her. At the same time, he is being pursued by a polymorphic specter, which XANA is able to create due to its new increase in strength and power. The others go to Lyoko to deactivate the tower but are all devirtualized by a giant wall of Bloks. Odd destroys the wall using a scanner eyepiece programmed by Jeremy and deactivates the tower. Meanwhile, Jeremy's computer is set on repairing a corrupted video file recovered from the Cortex. Eventually the task is completed and the gang watch the clip of Franz Hopper, furious at an employee who stole some documents of his. He fires the man and storms out, but the man remains in the room and laughs, calling Franz too naïve. Aelita identifies the man as Professor Tyron though she had never heard of him before.

The gang return to the Cortex to get data on the mysterious Ninjas. Ulrich opts out of the mission because he has a karate competition to attend, and Jim won't let him skip it. The others don't fare well against the Ninjas until Ulrich arrives, offering them advice that Jim passed on to him; be unexpected. With the advice given by Ulrich, and a new-and-improved, unusually effective bo staff weapon programmed for Yumi, she manages to defeat the three Ninjas easily and gathers the data. In it they find a video clip of Professor Tyron addressing several humans dressed in ninja-like costumes. Ulrich wins the competition and gives his trophy to Jim, thanking him greatly for his advice.

Jeremy manages to develop a program that will allow the gang to hack Tyron's surveillance system and spy on him, both using video and sound, and potentially speak to Anthea. When the gang go to the Cortex to implement it, all but Aelita are devirtualized by Ninjas when they tip off an unforeseen security system. Aelita opts to stay in the Cortex's core to wait for her mother to appear, asking for a clone to replace her at the school while she's gone, which causes enough problems of its own. In the end, Aelita is able to speak to her mother, convincing her that she is alive before she, too, is devirtualized by Ninjas. The experience initially leaves her feeling very sad, but after Jeremy assures her that Anthea got the message, her spirits are rekindled.
