We all know, that more than 9 centuries ago, in Ancient Japan / China, their were four nations. Air benders, Water benders, Fire benders, and Earth benders. Seperated by the no mercy Fire Lord. After the Avatar, a 12-year old kid was saved from a ice berg, by two water tribe people, he worked to learn the other elements and (meeting a blind Earthbender along the way) defeated the Fire Lord. Now, in the 21st century, 5 kids dealing with high school problems, have more to deal with after they find out that they are the descendants of those great hero's that once walked this Earth 900 years ago. Can they, save the world like their Ancestors?
