Complete story — includes the ending
Aang, Katara, and Sokka camp near a small Earth Kingdom town where they meet a young earthbender named Haru. They find the town is occupied by the Fire Nation, and earthbending is forbidden with risk of imprisonment. Katara convinces Haru to save an old man using his earthbending, only for the same man to turn Haru in to the Fire Nation. Katara devises a plan to save Haru by getting herself arrested for earthbending, which she fakes with some help from Aang and Sokka. When she arrives at the Fire Nation prison, a metal sea fortress that is impervious to earthbending, she finds Haru and his long-imprisoned father Tyro. However, she also discovers that all of the prisoners have lost hope of escape due to their inability to bend. Katara successfully leads a rebellion with Aang and Sokka's help by delivering the earthbenders coal from the fortress, which Katara uses to inspire them into action. The earthbenders escape after battling the Fire Nation guards, and head for their occupied towns with plans to rebel against Fire Nation occupation. Haru thanks Katara for reuniting him with his father, and Katara is shocked when she realizes her late mother's necklace is missing, found by Zuko back on the fortress.
