In search for an earthbending teacher for Aang, the kids go to an underground earthbending tournament called Earth Rumble 6. There they meet Toph (aka the Blind Bandit), a blind, but powerful earthbending girl. After seeing her unique style of earthbending, Aang wants Toph to become his teacher, but they find out Toph has hardships of her own. Will Aang manage to convince Toph, or will he be left without an earthbending teacher?

When a mysterious vehicle follows Aang's group they try to escape but it appears every time they try to rest. They confront it, but Azula emerges and attacks and they are forced to run again. The tension grows among them and Toph leaves the group and finds help from an unlikely source. Meanwhile, Aang tries to draw their pursuers away and finally faces off against Azula. Zuko also arrives determined to claim his prize.
