Code Lyoko

During class, everyone's cell phones suddenly go off, and all of them are confiscated. Sissi is not happy about this and organizes a protest in response. Yumi joins the protest, since having cell phones is a necessary part of the group's fight against X.A.N.A. X.A.N.A. is using the school's antenna to take over the nearby television antenna. From there, he could take over a laser-equipped, military satellite.
