Superman and the Flash get together to stage a "Fastest Man Alive" charity race. However, the monitoring arm bands placed on them have been rigged by Mark Mardon, a petty extortionist who is using his brother's technological genius to control the weather and siphon off 'ionic energy' from the racing superheroes. Mardon plans on extorting a billion dollars with his weather threats. After his brother turns against him he tries to kill him, which attracts the attention of the two superheroes. Together they take down Mardon when his weather-control wand goes out of control and come to a grudging mutual admiration.
