Code Lyoko

To free William from X.A.N.A., the Lyoko Warriors must return to Siberia for Jeremie to implement his program in the Ice Sector Replika's supercomputer. However, this will not be easy with William, X.A.N.A's new army, and the seemingly unstoppable Kolossus all standing in their way. Meanwhile, William's parents come to Kadic to visit their son, and the Clone's odd behavior begins to raise their suspicions.
