Two of 20th Century Fox's biggest franchises ever - Alien and Predator -come together in one movie! A mysterious structure has been detected via satellite far below the ice at the bottom of the world. Assembled by a billionaire industrialist, a crack team of scientists, drillers, archaeologists and adventurers has traveled to the Antarctic wastes to make history by exploring what is believed to be a fully preserved pyramid predating those built by early Egyptian and Mexican civilizations. But once this expedition crew enters, there will be no way out - and no hope left for humankind. Because deep within the labyrinth, a terror is stirring - an alien monstrosity more vicious, cunning, evil, and unstoppable than any species in the universe - except one: the other-worldly Predators who brought the nightmare to Earth to begin with and who are now returning here to face the beast once more in the most unholy combat. The battle is about to begin - and to the victor will go the planet.
