Finale Part 1

Jiangcheng City took the lead in deploying the country's first "artificial intelligence police" system - massive data collisions in seconds, cross-regional cases intelligent concatenation, and suspect trajectories restored in minutes. When this system was first used to detect serial murders, criminal psychologist Wei Lin raised objections: AI can lock the behavior trajectory, but can it understand the motivation behind the behavior? Forensic doctor Liu Ling also faces challenges: DNA three-dimensional face reconstruction technology can restore the face of the real murderer from genes, but when the technology points to an "impossible person", should you trust the data or your intuition? This is a joint hunting of human wisdom and artificial intelligence - the prey is the most dangerous serial killer.
