Our heroes befriend a young Earthbender named Haru. However, Haru has to train in secret, as his village is under the control of the Fire Nation, who have outlawed earth bending for fear of a rebellion. The gang encourages him to improve his skills; however, he is found out, and taken by the Fire Nation into slavery. Katara pretends to be an Earthbender in hopes to orchestrate a rescue, and she, with back-up from Aang and Sokka, must somehow get the imprisoned to help themselves.
