The robots have created a duplicate of Sensei Keiken! Using this fake, they've infiltrated the Exo-Force headquarters and destroyed the jamming system--the only thing that prevents the robots from invading the Golden City!

The Exo-Force team must find away to fight back or everything will be lost and the robots will finally win. And once the battle is over, the team must figure out what happened to Sensei Keiken and where he is now.
