What will happen if your brain locates a memory that doesn't belong to you? In 2025, the memory-manipulation operation has been popularized across the world. Feng, a prestigious novelist (Huang Bo), deletes the memory of his failed marriage. But when he tries to recover the lost memories, he finds himself in the mind of a serial killer. He reaches out to police officer Shen (Duan Yihong) and when they begin to solve the case together, a vast conspiracy surfaces that endangers everyone around them. In Chinese with English subtitles.
