The Avatar is gone. He was not there when the fire nation invaded the earth kingdom and he is not here now, when a small group of rebels hiding in ancient ruins does its best to survive. Lee is one of these rebels and leads a small team that ventures regularly into a city governed by the fire nation in order to steal food and daily necessities. However the fire nation soldiers are not his only enemy. Some of his own comrades despise him and do everything they can on order to turn his life into hell. Above all Lee hides a dark past he can not even tell his closest friend Roku because he fears that even he would turn against him if he knew the whole truth. Then it all changes when a new refugee reaches the ruins. Her name is Sora and she is an airbender. Even though she is still so very young she insists to join Lee's team and fight alongside them. Then it all takes a turn for the worst because a new commander takes over in the city who has sworn to himself to slaughter all rebels. They have to fight for their lives and between it all Lee's darkest secret gets exposed.
