“A beast exists within us all.”

In a South Korean city, a doctor named Seung-hoon (Cho Jin-woong) treats a patient under sedation and hears him let slip a secret about an unsolved serial murder case. Soon dismembered bodies begin turning up close to where he lives, and director Lee Soo-youn keeps the investigation tight around him. Seung-hoon has to work out the riddle before the killer learns what he heard, and every day he waits costs him more.
