Two hundred years after Lt. Ripley died, a group of scientists clone her, hoping to breed the ultimate weapon. But the new Ripley is full of surprises … as are the new aliens. Ripley must team with a band of smugglers to keep the creatures from reaching Earth.

While Sigourney Weaver's feral performance as a resurrected Ripley restores some fun to the Alien franchise, the acid blood running through this fourth entry's veins corrodes whatever emotional investment audiences had left.
