A mysterious group breaks out Ozai and Azula from their prison. They go over to an island off the south coast of the Fire Nation, and the Gaang is right on their trail. Arriving on the island, an abandoned resort town is settled there where things are not what they seem when they enter it. Soon, they will be tested beyond the reaches of their emotions and mind, while a darker plot is happening on the island. When they enter the town of "Silent Hills"...there's no turning back.
