Grace dies from her wounds. Jake manages to unite all the Na'vi tribes against the humans, and stops their plan to extract the Unobtainium. In the process, Neytiri kills Colonel Quaritch. All the humans, except for those who sided with the Na'vi, are forced to return to Earth. The great tree deity grants Jake his wish and transfers his spirit to the Na'vi avatar so that he can be with Neytiri forever.
