Washington, D. C., Where The Exorcist takes place, is making waves again. Father Karras's lifelong friend and old detective Kinderman is responsible for investigating a series of murders. The criminal characteristics of the criminals are almost consistent with the Gemini killer who has been executed long ago. At the same time, this series of murders also had blasphemous characteristics. The newsboy was nailed to a cross-shaped oar after being killed, and the priest was beheaded while listening to prayers. These events cannot help but remind Kinder United of the case of the little girl Li Gan's possession twelve years ago. Kinderman investigates the case with doubts. Will the murderer be the old woman who witnessed it? Will it be the neurologist who cannot bear the pain of losing his wife? Could he be a psychiatrist who loves to use hypnosis on his patients? In the end, he pointed the finger at a mysterious man who had lived in a mental hospital for twelve years... Back then, everyone thought that the nightmare disappeared with the death of Father Karas. How could it reappear now?
