A string of “deaths without a mark” takes place in Binhai City. The victims’ pupils are frozen with mysterious symbols, while nanchips hidden inside their bodies hijack their neural signals and trap them in virtual spaces of fear. During his investigation, former Interpol officer Lin Yuan discovers that the barcode tattoo on the back of his neck is actually the identification mark of Subject 47, a clone from the “Adam Project.” This perfect detective, an experimental subject implanted with a nanchip, has been caught up in a genetic conspiracy spanning twenty years ever since the day he was created.
