A half-naked body discovered by chance turns out to be the fourth victim in a string of murders. But as Officer SA's investigation deepens, it becomes clear that this series is unlike any ordinary string of killings. The victims share no similarities or connections, leaving the case at an impasse. Meanwhile, H, the person who discovered the body, becomes the one to find another corpse: a famous lawyer. Strange words and actions, along with an inscrutable pattern of behavior, implicate a whole chain of people. Who is the real mastermind: the odd restaurant owner, the eerie magician, the university professor, or perhaps even a police officer?
