A serial killer named Shin-Hyun gives himself up to police. He confesses to committing a series of particularly horrifying murders of exclusively female victims. He is imprisoned, awaiting the death sentence for his crimes. Yet the killings do not stop. They continue with all the same characteristics trademarks of the Shin-Hyun serial killings. The case is re-opened when two more bodies are discovered, both pregnant women. One is found in the city's landfill site, and the other is horrifically murdered on a public bus. Detective Mi Yun (played by Yum Jung-Ah), and her newly appointed partner, Detective Kang (played by Ji Jin-Hee), are assigned to the case.
