James Cameron's third Avatar movie is turning the rules upside down, introducing a nefarious Na'vi clan as the human invaders go all-out.

The official logline for Avatar: Fire and Ash teases, “Jake and Neytiri’s family grapples with grief after Neteyam’s death, encountering a new, aggressive Na’vi tribe, the Ash People, who are led by the fiery Varang, as the conflict on Pandora escalates and a new moral focus emerges.”
