Set more than a decade after the events of the first film, learn the story of the Sully family (Jake, Neytiri, and their kids), the trouble that follows them, the lengths they go to keep each other safe, the battles they fight to stay alive, and the tragedies they endure.
In the near future, Major (Scarlett Johansson) is the first of her kind: A human saved from a terrible crash, who is cyber-enhanced to be a perfect soldier devoted to stopping the world's most dangerous criminals. When terrorism reaches a new level that includes the ability to hack into people's minds and control them, Major is uniquely qualified to stop it. As she prepares to face a new enemy, Major discovers that she has been lied to: her life was not saved, it was stolen. She will stop at nothing to recover her past, find out who did this to her and stop them before they do it to others...
