A viral outbreak on a remote South Pacific island lures a secret expedition to investigate. The natives there are dying from a lethal cocktail of neurotoxins and the most likely cause is a venomous spider bite. The suspect - a previously unknown species of arachnid. Now, a terrifying predator with a voracious appetite and a killer instinct is hunting ex-Navy pilot Lauren Mercer and her team of soldiers and scientists. To make matters worse, the thing is multiplying at a ferocious rate. And when Mercers team finds the wreckage of a crashed spaceship, it becomes clear that the extraterrestrial arachnid is more than just a new species of spider.
