On February 15, 1994, Director Tak Myeong-hwan, South Korea’s first cult hunter, exposed the shocking crimes of a cult on national television. Three days later, he was assassinated outside his apartment. The investigation identified the killer as Lim Hong-cheon, the driver of a pastor from a church Tak had recently begun tracking. Despite strong suspicions of a mastermind, the case was closed as a solo crime.
Left behind, Tak's three sons followed their father's destiny, quietly becoming cult hunters themselves. The killer was released 15 years later and left the country.
Then, in the summer of 2022, an unexpected Telegram message shatters the sons' lives:
"Do you want to know the truth hidden behind your father's death?"
To uncover the secret of the assassination, Tak’s sons reach out to cult hunters worldwide and embark on a dangerous journey to find the truth.
