The government says there's nothing to worry about - it's just a problem with bears making trouble in the mountains and forests of Norway. But local hunters don't believe it - and neither do a trio of college students who want to find out the truth. Armed with a video camera, they trail a mysterious "poacher," who wants nothing to do with them. But their persistence lands them straight in the path of the objects of his pursuits: Trolls. They soon find themselves documenting every move of this grizzled, unlikely hero - The Troll Hunter - risking their lives to uncover the secrets of creatures only thought to exist in fairy tales.
