Jake is a war vet, and, after he gets paralyzed, the military gives him a chance to serve Earth once again. He arrives on Pandora, a beautiful yet lethal planet and tries to learn as much as he can about the humanoids that inhabit it and look like ancient humans but are, in fact, a lot more advanced. Jake links with an Avatar - a hybrid - and travels the lush surface of Pandora in an attempt to figure out the weaknesses of the Na'vi and to report back to higher command. However, when he falls in love with a beautiful local woman, everything changes. Soon, he finds himself fighting side by side with the Na'vi and battling humans.
