Aang is a young expert in air manipulation, but above all he is the Avatar, an exceptional individual capable of controlling all the elements - Fire, Air, Water and Earth. Caught in a violent storm, he falls into the ocean and enters hibernation thanks to his Avatar abilities, only to awaken a century later in a world oppressed by the powerful Fire Nation, where he is the last survivor of his people.
With the help of his two allies from the Water Tribe, Aang must awaken the Avatar within him, master all the elements and fight against the threat posed to the world by the Fire Nation.
