Aang and his friends fly to the island of Kyoshi, where Aang is revered by the people, but the Fire Nation attacks while he's there. With Kyoshi in flames, a female warrior named Suki may be the only hope for peace.
Aang excitedly takes Sokka and Katara to visit the Air Temple where he was raised, but finds it changed. Everyone he knew is dead or is 100 years old. But, the temple unlocks some of the secrets of the Avatar and he leaves his old home with new purpose.
Aang and his friends make it to the beautiful city of Omashu, but soon find themselves on the wrong end of the law. To regain their freedom, the mad king puts Aang through a series of tests.
