After a number of flying men are spotted over Capitol City, Matt Ritter learns that the men are part of a group called the "Katia," descendants of African slaves who gained the power to fly. When Matt discovers he is one of them, he quits his job at the Bureau and joins the group. But Clark and Lana find out that there is a connection between the Katia and a series of fires that have broken out throughout the city, and if the Katia aren't stopped, Capitol City could burn to the ground.
