"Air, Water, Earth, Fire. Four nations tied by destiny when the Fire Nation launches a brutal war against the others. A century has passed with no hope in sight to change the path of this destruction. Caught between combat and courage, twelve-year-old Aang (Noah Ringer) discovers he is the long-lost Avatar with the power to control and manipulate all four elements. Aang teams with Katara (Nicola Peltz), a Waterbender, and her brother, Sokka (Jackson Rathbone), to restore balance to their war-torn world.

"Based on the hugely successful Nickelodeon animated TV series, the live-action feature film “The Last Airbender” is the opening chapter in Aang’'s struggle to survive." — Official site

The Fire Nation is waging a ruthless war to control the other great nations. The only hope for stopping the war rests on the shoulders of a reluctant young boy named Aang. The last known Airbender and survivor of the peaceful Air Nomads, Aang is the Avatar. The Avatar is the physical embodiment of the world, with the ability to control all four elements and draw upon the combined power, knowledge, and experience of the Avatar's previous incarnations. The Avatar's duty is to maintain peace between the four nations and the spirit realm, ensuring that the world remains in balance, a balance threatened by the Fire Nation's war. Aided by a protective teenage Waterbender named Katara and her warrior brother Sokka, Aang begins a perilous journey to restore balance to their war-torn world. Standing in their way is the ambitious Fire Nation Admiral, Zhao, (Aasif Mandvi) and Prince Zuko (Dev Patel), the banished prince of the Fire Nation who seeks to capture Aang to regain his honor.

The Last Airbender will roughly follow the course of the first season of the original TV series. From the various trailers and promotional material released by Paramount, it has become evident that elements such as Aang's reappearance at the Southern Water Tribe and the epic battle, the Siege of the North, at the Northern Water Tribe, will be incorporated.
