The episode begins with Jeremie in the factory. The others are in Lyoko - Jimbo included, but Jeremie keeps telling Jim to go a little faster in his attacking, as he has just lost over twenty life points. They beat the monsters, deactivate the tower and, just in case, do an RTTP. That night, Jim tells Ulrich and Odd good night and to have sweet dreams, and he walks into his room. He sees a shooting star and prays, wishing that he was a teenager again. He then gets into bed and falls asleep.
The next morning, Jim wakes up, only to find that his body has become that of his teenaged self! He screams in excitement, and says that his wish came true! He runs into Ulrich and Odd's room in excitement, and they are shocked to see their (now-former) PE teacher as a teen. A while later, during science class, Mrs. Hertz walks in, and the whole class is in shocked silence - she too is a teenager!
XANA sees this as a sweet opportunity to attack the school. He send three Megatanks to damage the dorm building. Unfortunately Suzanne is hit. Luckily though, Jimbo catches her. At the factory, Jeremie says that XANA has activated a tower, and sends the others to the scanner room. They are virtualized.
When Jim is virtualized, he is surprised to discover that even his virtual body is now a teen form. He is very excited, and attacks the monsters as quickly as his friends. They deactivate the tower and do an RTTP.
Later, that night, Suzanne asks Jim out on a date, at the Cafe Sequin. He is blushing as red as a tomato. Odd agrees, stating that they all are going to go out there for dinner. To the surprise of the others, Jimbo kisses Suzanne!
