A human trafficker is infected with an unknown virus and dies in a Bundang hospital, covered in red rashes and coughing up blood. Less than 24 hours after the death of the first patient, similar cases are reported all over Bundang. The medics despair over the super-virus that has no known cure, but they soon find hope when they hear of a sole survivor who may have developed antibodies against this ruthless viral mutation. As medical professionals rush to find the sole individual with the potential key for a cure, fatalities rise, and soon the government has no choice but to quarantine the city. Amidst the ensuing panic, wild desperation and violence, the struggle for life between the infected and non-infected begins to spiral out of control.
