The story unfolds during the Great Exhibition of technological breakthroughs in Victorian England, in the mid-nineteenth century. Ray is a boy, the son and grandson of two renowned inventors, who has dedicated himself since childhood to creating amazing machines powered by steam. One day, his grandfather Lloyd returns from the United States, where he has been working with his son on a secret project for the multinational Ohara Foundation, and hands the boy a metal ball capable of producing immense energy. This marks the beginning of the boy's adventures, as he is hunted from that moment on by the henchmen of the U.S. company and its competitors, who are eager to retrieve the precious item needed for their major project: the imposing Tower Steam, the ultimate war machine. The narrative presents a clash of generations between father, son, and nephew, exploring their differing worldviews and values, while offering a brilliant critique of modern society and war.
