Milla Jovovich is back as Alice and she's running with a new pack of humans, leading a caravan that's cutting through the Nevada desert on a long trek to Alaska. Hunted by the minions of the perpetually scheming Dr. Isaacs, Alice has zombies hungry for her flesh and lab rats hungry for her blood -- while Alice herself is hungry for only one thing: revenge.

Resident Evil: Extinction opens on September 21st, 2007.
