When a young waterbender, named Katara, and her brother, Sokka, discover a giant iceberg while fishing for food around their homestead at the South Pole, they discover that there is a boy, named Aang, inside.
After Aang accidentally sets off a Fire Nation trap, he is banished from the South Pole. Soon after Prince Zuko attacks the Southern Water Tribe seeking to capture the Avatar. Aang returns and surrenders to save the Water Tribe.
Aang is eager to take Sokka and Katara to the Air Temple where he was raised. But upon arrival, it becomes apparent that the temple is not at all how Aang remembers it.
As one of Aang's little detours, the group heads toward the island of Kyoshi. But soon they learn that the townspeople don't trust foreigners at all; however, when Aang proves to them that he is the Avatar they are treated as guests of honor.
Aang takes Katara and Sokka back to a favorite place he used to go to when he was younger, the Earth Kingdom City of Omashu. But when they break the law they are taken to the King to get their punishment.
The kids come to an Earth Nation town which is occupied by the Fire Nation. But will Katara’s attempts to inspire the oppressed people help them or hurt them?
