In the remote South Korean village of Hope Harbor, police chief Bum-seok (Hwang Jung-Min) and officer Sung-ae (Hoyeon) are given the mission to find a mysterious creature that has sown chaos among the inhabitants.
Meanwhile, in the forest, a group of hunters, among them Sung-ki (Zo In-Sung), venture in search of it, but soon discover that they are the prey. As the creature continues to wreak havoc, nothing is as it seems. What they believed was a conflict that could be resolved by humans ends up escalating into a catastrophe of cosmic dimensions.
