The story's hero is Jake Sully, an ex-Marine confined to a wheelchair. Bitter and disillusioned, he's still a warrior at heart. All Jake ever wanted was something worth fighting for and he ultimately finds it in the place he least expected- on a distant world. Jake has been recruited to join an expedition to the moon Pandora, which corporate interests are strip-mining for a mineral worth $20 million per kilogram on Earth. To facilitate their work, the humans use a link system that projects a person's consciousness into a hybrid of humans and Pandora's indigenous humanoid race, the Na'vi. This human-Na'vi hybrid - a fully living, breathing body that resembles the Na'vi but possesses the individual human's thoughts, feelings and personality - is known as an "avatar." In his new avatar form, Jake can once again walk. His mission is to interact with and infiltrate the Na'vi with the hope of enlisting their help - or at least their acquiescence -- in mining the ore. A beautiful Na'vi female, Neytiri, saves Jake's life - reluctantly - because even in his avatar body, Jake represents to her the human encroachment on the Na'vi's unspoiled world. As Jake's relationship with Neytiri deepens, along with his respect for the Na'vi, he faces the ultimate test as he leads an epic conflict that will decide nothing less than the fate of an entire world.
Rated PG-13 by the Motion Picture Association of America intense epic battle sequences and warfare, sensuality, language and some smoking.
