Set more than a decade after the events of the first film, it begins to tell 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.

When Mulan's aging father is drafted into the Imperial army to fight the invading Hun army, she disguises herself as a soldier and takes his place. Mulan's hilarious guardian dragon and lucky cricket are not enough to help her defeat the ruthless Hun leader, however; only by staying true to herself will she bring victory to her country and honor to her family
