In the neon-lit cyber city, Shen Yumo, a talented female police detective with emotional disorder, pursues a series of strange "memory stripping cases". The specific sensory memories of the deceased were precisely erased, and the scene was as clean as ever. The police asked her to cooperate with Chu Ruilu, a psychic suspect who could see fragments of other people's memories, and the latter claimed that her face was in the murderer's memory. After in-depth investigation, Shen Yumo discovered that each case strangely overlapped with her own blocked childhood memories - the "fire" when she was six years old, the music of the carousel, and the figure under the transparent raincoat. As clues point to the illegal memory experiment "Project Gardener" that the military has long buried, she must face the ultimate truth: she is not only a detective, but also the last piece of evidence to be recovered in this memory hunt.
