Meanwhile, Jake discovers that all is not well in a small town, with its inhabitants seemingly acting like zombies. With the President's train passing though the area soon, the Centurions examine the place further. They find that the townspeople are under the control of Zombie Master, who is working for Terror. He intends to turn the World President into a zombie when his train passes through the town, controlling him. Of course, only the Centurions can stop him. Science Lesson: Steam power by Jake.
