Synopsis for "The World of Tomorrow"
Clark Kent and Lois Lane attend an exposition of The Biosphere, an environmentally self-sufficient city of the future when suddenly they are attacked by Tobias Manning, an eco-terrorist, and his henchmen. Obsidian and Jade, who were hired to make the visual effects of the exposition, try to apprehend the attackers. Superman intervenes and realizes the henchmen are robots, so he disables them. Manning escapes by creating a tornado. Superman goes back to his Clark Kent clothes and reunites with Lois, continuing their date in Kansas.
Meanwhile, Jimmy Olsen keeps meeting with Jerry White at his new nightclub, Blazes, but Lucy Lane breaks up with him.
