Highlights
In 2003, South Korea witnessed a string of murders targeting wealthy families, leading the police to suspect a serial killer.
The police discovered the bodies of a family in a wealthy Seoul neighborhood, showing no signs of forced entry, leading them to suspect someone close to the family.
Similar murders occurred in a different area, involving brutal head trauma, causing investigators to suspect and link a serial killer to these crimes.
Criminal profiler Young-Gon is brought in to create a profile of the suspect, suggesting the killer holds a vendetta against the rich.
Suddenly, new attacks began on women in the city, seemingly without the same pattern as the previous crimes, leaving the police baffled.
A former police officer, now a manager in the district, receives a call from a suspect using a missing victim's phone, leading to the suspect's capture.
The suspect, Yoo Young-Chul, is arrested and confesses to killings of the wealthy, as well as women in the new type of crime.
Yoo Young-Chul's case leads to significant police reforms, and he is sentenced to death, yet remains in South Korean prison.
In 2006, it emerged that a different serial killer was responsible for some of the crimes Yoo was initially credited with, revealing manipulation within the investigation.
Despite Yoo's conviction, the case highlighted flaws in the police system and catalyzed necessary reforms in South Korea.
