In 2154, Earth suffers from resource exhaustion and ecological collapse. The Resources Development Administration (RDA) mines the valuable mineral unobtanium on Pandora, a lush habitable moon in the Alpha Centauri star system. Pandora is inhabited by the Na'vi, a , blue-skinned, sapient humanoid species that live in harmony with nature.
To explore Pandora, human scientists control Na'vi-human hybrid bodies called "avatars". Each avatar is genetically matched with a human operator. Jake Sully, a paraplegic veteran of the United States Marines, is recruited as an operator after the death of his identical twin, who was training as an operator. The head of the Avatar Program, Dr. Grace Augustine, allows Jake to take the place of his twin, but considers him inadequate.
While Jake, Grace and Dr. Norm Spellman are in their avatars in the forest, Jake is attacked by wild animals. He flees deep into the wilderness, where he is rescued by a female Na'vi named Neytiri. Suspicious of Jake, she takes him to her clan, the Omaticaya. Mo'at, the clan's spiritual leader and the mother of Neytiri, orders her daughter to initiate Jake into their society.
Colonel Miles Quaritch, head of the RDA's security force, promises Jake that the company will restore the use of his legs if he provides information about the Na'vi and their gathering place, the giant Hometree, which sits atop a rich deposit of unobtanium. Jake and Neytiri fall in love as Jake is initiated into the clan, and they choose each other as mates. When Jake attempts to disable a bulldozer threatening a sacred Na'vi site, RDA administrator Parker Selfridge orders the destruction of Hometree.
Grace explains to Selfridge that destroying Hometree would damage the biological neural network that connects all Pandoran life, which prompts Selfridge to reluctantly give Jake and Grace one hour to convince the Na'vi to evacuate. Jake confesses to the Na'vi that he was a spy for the RDA, which prompts the clan to take him and Grace captive. Quaritch's soldiers destroy Hometree and kill many Na'vi, including Eytukan, who is the clan chief and Neytiri's father. Mo'at frees Jake and Grace, but they are detached from their avatars and imprisoned by Quaritch's forces. Trudy Chacón, a pilot who is disgusted by Quaritch's brutality, rescues Jake, Grace, and Norm. During the escape, Grace is shot and fatally wounded.
Jake regains the trust of the Na'vi by connecting his mind to the Toruk, a dragon-like creature feared and revered by the clan. Supported by Neytiri and the new chief Tsu'tey, Jake unites the Omaticaya, and tells them to gather other Na'vi clans to fight the RDA as it prepares to assault the Tree of Souls. Before the battle, Jake prays to the Na'vi mother goddess Eywa through a neural connection with the Tree of Souls.
The Na'vi and their human allies lose many fighters during the battle, including Tsu'tey and Trudy. The tide turns when wild animals unexpectedly join the fight and overwhelm the RDA forces; Neytiri interprets this occurrence as Eywa answering Jake's prayer. Quaritch, in an Amplified Mobility Platform suit, breaks open the avatar link unit containing Jake's human body, exposing it to Pandora's poisonous atmosphere. As Quaritch prepares to kill Jake, he is slain by Neytiri, who then saves Jake from suffocation.
In the aftermath of the war, the RDA is expelled from Pandora. Some humans are allowed to remain, including Jake and Norm. With the help of the Tree of Souls, Neytiri, and Mo'at, Jake is permanently transferred into his avatar.
