Water. Earth. Fire. Air. In the old days, there was peace between the four nations of the world. The Avatar -- Master of all four elements -- kept peace between the the Water Tribes, the Earth Kingdom, the Fire Nation, and the Air Nomads.
Only the Avatar has the ability to Bend (manipulate) all four elements, but one day, he Vanished. Then the Fire Nation attacked, forcing a war on the other three nations for one hundred years. Now, for the good of the world, it's up to 12-year-old Aang (Noah Ringer), the new Avatar, and the last of the Air Nomads (Airbenders), to return peace and balance by putting an end to the war and mastering all four elements.
Aang must accept his destiny by stopping the Fire Nation's war and defeating the Fire Lord for good.
