10 days have passed since the King collapsed from an illness. Queen Jo (Kim Hye-Jun) and her father Chief State Councilor Jo Hak-Joo (Ryoo Seung-Ryong) have forbidden anyone else to see the King. Even his own son Crown Prince Lee Chang (Ju Ji-Hoon) is forbidden to see his father. In the meantime, Chief State Councilor Jo Hak-Joo rules Joseon with an iron fist, but rumors spread that the King is dead.
Crown Prince Lee Chang senses something sinister and sneaks into the King's palace. He sees a shadowy monster through a door and smells its foul stench, but he is discovered and escorted out of the palace. His guard Moo-Young (Kim Sang-Ho) steals the medical journal for the King. The journal is nearly empty, but lists the name of Physician Lee Seung-Hui (Kwon Bum-Taek). To find out what happened to the King, Crown Prince Lee Chang and Moo-Young travel to the Jiyulheon clinic in faraway Dongnae to see the physician. When they arrive, they discover that the clinic is in ruins and dead bodies are found under a building. Crown Prince Lee Chang and Moo-Young later learn that the only person to have survived the clinic is medical staff member Seo-Bi (Bae Doo-Na). When they finally find Seo-Bi, she tells the them that the dead they saw at the clinic are not dead and they will rise up soon to kill.
