Binhai City is a modern city famous for its high-tech and mental health industries.
However, in the shadows of the city, a serial killer who calls himself "Shepherd" is weaving a web of death.
He doesn't use weapons, leaves no traces, and doesn't break into homes. He just uses -
Psychological manipulation.
Through superb hypnosis, emotional manipulation and spiritual guidance, the "Shepherd" makes the victim believe that death is not the end, but the beginning of freedom; death is not pain, but the ultimate beauty; death is not the end, but his gift to the lamb.
The victim "voluntarily" walked to death with a satisfied smile on his face, as if completing a sacred ritual.
The only clue they left behind was a bracelet on their wrist. The pendant was engraved with a strange symbol - the shepherd's mark.
