WARNING: Legend of Korra season two and possible season one spoilers ahead.
Story: Korra and the new team avatar must stop a group of highly dangerous criminals from fulfilling a terrible plan that could bring about chaos, destruction, and death across the entire world. With the portal to the spirit world left open after the events of the last season, the world is coming to terms with the new spirits co-existing with them, which is producing much hostility. The still opened portal has also had unexpected results. Certain people around the world have suddenly being inundated with air-bending powers. Our heroes, Tenzin in particular, are intent on finding, educating, and training the first new air-benders (who are not descendants of Ang) in more than a century. Unfortunately, the leader of our villains is one of those who has been given air-bending abilities. The three other antagonists are all experts in their bending (earth, fire, and water), and with a quickly learning air-bender who’s proficient in the history and ancient ways of air-benders, they are a force to be reckoned with. They might also be too much for Korra and her friends.
