A young police officer discovers that rural life can be even more treacherous than city living when he reports to his new post in a remote village, and a monstrous, man-eating boar begins feasting on the locals. Perplexed by the rash of violent murders that has rocked their quiet hamlet, the incompetent local authorities call in a veteran detective to catch the killer. Shortly thereafter, an ambitious Seoul policeman arrives in the village, and quickly determines that the culprit isn't human. But catching the beast won't be easy, and in order to do the job right they'll need the help of some seasoned hunters. Later, while searching the back woods for the elusive flesh-eater, the hunting team unearths evidence it could be the result of a wartime experiment gone horribly awry. Now, the hunters have become the prey, and as the beast begins its feast, these once-peaceful woods will be filled with a symphony of blood-curdling screams.
