Ep 17. Satellite

Right in the middle of science class, all the students' mobile phones start ringing. But when they answer, there is no-one on the line. Mrs. Hertz confiscates everyone's phone. Jeremy realises that X.A.N.A. is behind these ill-timed rings. The super calculator is using the communications antenna to take control of a very powerful military satellite which it could use as an instrument of mass destruction! Only a victory on Lyoko can save the day and above all , Yumi, who is X.A.N.A.'s first target.
