Code Lyoko - Season 1 - Eps 16: Claustrophobia
After a quick game of soccer, Yumi heads home for the night, but Odd and Ulrich head in for dinner, and Jeremie is already there. He decides to check on Aelita, and Yumi ends up following him instead. But, while scarfing the desserts the others left behind, he and Ulrich get caught up in a shocking Xana trap. Not only is the lunchroom electrified, the roof may fall in at any time. Even the combined power of the eight kids trapped inside - including Odd, Ulrich, and Sissy - can only delay Xana for a short time. Will Yumi be able to get Aelita to the tower before the room becomes a final resting place for our heroes?
