Brothers Feng Ling and Yun Ling grow up alongside a wide circle of friends and rivals, all of them drawn into the sport of remote-controlled car racing. Staying with their uncle while their parents are away, the twins learn about the hobby from a classmate. One of them first dismisses it as a game for little kids. After school they head to a racing club, where their first race goes very differently for each brother. At a car shop they find out that climbing to higher levels means upgrading their machines with spoilers and new body kits. From there they take on a string of opponents on the way to the finals. The show pairs comedy with sports, and the brothers grow as racers throughout its 26 episodes.
