A cop tracking a ruthless criminal finds himself in the midst of an unfinished subway tunnel, when his flashlight reveals a startling discovery: a three-meter-long, scorpion-like bug who devours him after one slice of its massive tail. FBI agent Matt Pollack (Antonio Sabato, Jr.) is brought in to investigate, and when forensics reveal the source of the problem, he turns to his friend, insect specialist Emily Foster (Angie Everhart), for help...with chilling results. Now Matt and a team of crack SWAT commandos must go underground to battle these evil predators, but when the humans find themselves trapped inside a massive tunnel, they're forced to race against time and exterminate this menace before chaos and destruction consume the world above!
