In South Korea, when a man is murdered in his apartment with blisters, the coroner concludes that the killer died three months ago. The investigative journalist Im Jin Hee, who has just released a book and created an independent news channel named Urban Detective, is interviewed by the host of a show when a stranger calls and schedules an interview with her, saying that he is responsible for the recent mysterious death. Her husband, Detective Jeong Seong Jun, gathers several police officers to protect Im Jin Hee from the stranger. He discloses that Director Kim Min Seop, President Lee Sang In and his brother, the CEO Byun Mi-Yeong, of a big pharmaceutical company, will die unless they ask for forgiveness of his victims. When he is confronted by the police, he mysteriously dies, and he is another reanimated corpse. Jeong Seong Jun provides protection to the executives while Im Jin Hee and her team investigate the killers. Soon she concludes that the ambitious Byun Mi-Young, who is the daughter of Byun Mi-Yeong, conducted medical experiments with one hundred homeless people that died, and now a witch doctor is using the zombies to revenge them. She needs to find him to save her husband that was contaminated in a zombie attack.
