Shen Wei, a professor of criminal psychology at Tunghai University, was once a famous criminal profiler in the public security system. Due to an unbearable past, he took off his police uniform and closed himself in an academic ivory tower. Only his observation skills and logical thinking that were ingrained in his bones remained.
A seemingly accidental death of a graduate student on campus broke the peace. The police closed the case as suicide, but Shen Wei smelled the smell of murder from the password note tightly clutched in the body's hand and the subtle sense of dissonance. When he intervenes in the investigation, more bizarre deaths occur one after another, and each corpse becomes a coded beacon left by the murderer, pointing directly to the closely guarded top-secret research deep in the school-"Cradle Project."
The path to pursue the murderer is also the path to atonement. The murderer seemed to be peering into his past, and every step he took accurately stepped on his psychological shadow. Shen Wei must crack the bloody code while facing the dead souls he failed to save. When all the clues intertwine into an arrow pointing to himself, he must uncover the perfectly concealed truth before the next victim appears, and complete the ultimate profile of self-redemption.
