The film is set in the year 2154 on Pandora, a fictional Earth-like moon in a distant planetary system. Humans are engaged in mining Pandora's reserves of a precious mineral, while the Na'vi — the sapient and sentient race of humanoids indigenous to the moon — resist the colonists' expansion, which threatens the continued existence of the Na'vi and the Pandoran ecosystem. The film's title refers to the remotely controlled, genetically engineered human-Na'vi bodies used by the film's human characters to interact with the natives
In 2154, the RDA Corporation is mining Pandora, a lush, Earth-like moon of the planet Polyphemus, in the Alpha Centauri system. Parker Selfridge (Giovanni Ribisi), the administrator, employs former marines as mercenaries to provide security. The humans aim to exploit Pandora’s reserves of a valuable mineral called unobtanium.
Pandora is inhabited by the Na’vi, a paleolithic species of sapient humanoids with feline characteristics. Physically stronger and taller than humans, the indigenes have sparkling blue skin and live in harmony with Nature, worshiping a mother goddess called Eywa.
Humans cannot breathe Pandora’s atmosphere for long without passing out and dying. In order to move about Pandora, human scientists have created human-Na’vi hybrids called avatars, which are controlled by genetically matched human operators. Jake Sully (Sam Worthington), a paraplegic former marine, arrives on Pandora to replace his twin brother, who was killed in a simple mugging, an avatar operator. Dr. Grace Augustine (Sigourney Weaver), the head of the Avatar Program, considers him an inadequate replacement for his brother, who had undergone three years of training for the job, relegating him to a bodyguard role.
While Jake escorts Augustine and biologist Norm Spellman (Joel David Moore) on an exploratory mission in their avatar forms, the group is attacked by a large predator, and Jake becomes separated and lost. Attempting to survive the night in Pandora’s dangerous jungles, he is rescued by Neytiri (Zoë Saldaña), a female Na'vi. Neytiri brings Jake back to Hometree, which is inhabited by Neytiri’s clan, the Omaticaya. Mo'at, (C. C. H. Pounder), the Na'vi shaman and Neytiri's mother, interest by their first meeting with a warrior Dream-walker, as they call the Avatars, instructs her to teach him their ways.
Colonel Miles Quaritch (Stephen Lang), leader of the security forces, promises Jake his "real legs" back in exchange for intelligence about the natives and what it will take to make them abandon Hometree, which rests above a large deposit of unobtanium.
Over three months, Jake grows close to Neytiri and the Omaticaya and begins to prefer the life he lives through the avatar. Jake's attachment erodes his loyalty toward the humans, and when he is initiated into the Omaticaya, he and Neytiri choose each other as mates. Jake's change of loyalty is revealed when he disables a bulldozer's cameras as it destroys the tribe's sacred Tree of Voices. Col. Quaritch disconnects Jake from his avatar and presents Selfridge and Augustine with a vlog in which Jake admits that his mission is fruitless; the humans have nothing the Omaticaya desire, and the latter will never abandon Hometree. Selfridge is convinced that negotiations will fail and orders Hometree's destruction.
Augustine argues that the destruction of Hometree could affect the vast bio-botanical neural network that all Pandoran organisms are connected to, and Selfridge gives Jake one hour to convince the Na’vi to leave Hometree. When he reveals his mission to the Omaticaya, Neytiri accuses him of betraying them, which results in Jake and Augustine's imprisonment. Jake’s time runs out and Quaritch’s forces destroy Hometree, killing Eytucan (Wes Studi), Neytiri's father and clan chief, and many others. Jake and Augustine are disconnected from their avatars and detained for treason along with Norm. Trudy Chacon (Michelle Rodriguez), a security force pilot who is disgusted by the violence, breaks them out but Augustine is wounded by Quaritch. With Augustine dying, Jake turns to the Omaticaya for help. To regain their trust, he tames the Toruk, an immensely powerful flying beast that only five Na'vi have ever tamed. Jake flies to the Omaticaya, who have gathered at the sacred Tree of Souls, and pleads with Mo'at to heal Augustine. They attempt to transplant her soul into her avatar, but her injuries are too severe.
With the assistance of Neytiri and Tsu'Tey (Laz Alonso), the new leader of the Omaticaya, Jake assembles thousands of Na'vi from other clans. Jake prays to Eywa to intercede on behalf of the Na'vi in the coming battle. Quaritch, seeing the Na'vi's growing strength, orders a preemptive strike on the Tree of Souls; as it is the center of Na'vi religion and culture, its destruction would leave the Na'vi too demoralized to continue resisting.
As the humans attack, the Na'vi fight back but suffer heavy casualties, among them Tsu'Tey and Trudy. As the Na'vi are on the verge of defeat, the Pandoran wildlife suddenly attacks the humans, overwhelming them. Neytiri interprets this as Eywa answering Jake's prayer.
Jake destroys the bomber before it can reach the Tree of Souls. Quaritch escapes in an AMP (Amplified Mobility Platform) suit, finds the avatar interface pod where Jake's human body is located and attacks it, exposing Jake to Pandora's atmosphere. Neytiri kills Quaritch and saves Jake, seeing his human form. With the attack repelled, Jake and Neytiri reaffirm their love.
The humans are expelled from Pandora, while Jake and his closest co-workers remain. Jake is seen wearing the insignia of the Omaticaya leader. The film ends with Jake's soul being transplanted into his Na'vi avatar.
