Set in the present day, a dying billionaire discovers a pyramid in the Antarctic and sets about recruiting a crack team of specialists to take him to the site. Once there, the team become cannon fodder for a trio of Predators who use the ice-laden pyramid as a coming-of-age hunting site. That is, after they have infested the place with face-hugging aliens. It started with an in-joke that got out of hand. Now, after a long wait filled by various comic books and video games, Aliens finally get to take on Predators.
