Jae-hyuk is an ordinary man in his 40s. He works as a medical supplies salesman and is hassled by doctors all day. His brother Jae-pil is a detective that is not all that interested in public safety and spends most of his time moaning about the stock market. The discovery of a series of floating, gruesomely skeletal bodies around the country sparks hysteria. Time passes and hundreds of similar cases are reported, leaving officials stumped as to the cause of the deaths. The government declares a national emergency. Jae-pil joins the massive investi¬gation and realizes that there is a conspiracy behind the outbreak. Meanwhile, Jae-hyuk’s wife and children are showing the same symptoms as the victims, leading him to a frantic search for medicine. Through Jae-pil he learns of a warehouse containing a potential cure and heads there with no idea of what he’s heading into.
