Worldwide, there are thought to be 8,000 species of centipede, of which, only 3,000 have been scientifically recorded. The venom of Scolopendra gigantea—the largest of the arthropod genus found in the Amazon rainforest—is so potent that it is fatal to small animals and toxic to humans. But when a cargo plane departs the Amazon region and crashes inside a national park in the United States, much larger and deadlier creatures escape the wreckage to roam wild, reproducing at an astounding rate. Entomologist, Frank Travis solicits small town sheriff Wanda Rafferty’s help and together they investigate the crash site. But as a rash of gruesome deaths befalls the townsfolk of Prospect, Frank and Wanda will soon discover how vicious and cunning these new breed of predators can be. Meanwhile, Jake and Nora Carver, and another backpacking couple, are venturing up into the mountainous terrain of the park. If only they knew their fun-filled weekend is about to become a living nightmare.
