Opening scene: a camera sweeps high across the treeline of a lush, green world. Intercut is a sequence of images of Jake Sully, a crippled war veteran and former Marine.

While the other passengers disembark and take their first steps onto the base, called "Hell's Gate," which is surrounded by a huge perimeter fence. Jake follows them in his wheelchair, earning the moniker "Meals on
