In Los Angeles, Lt. Parker Barnes and John Donovan are tracking down a serial killer named SID 6.7 at a restaurant in virtual reality. SID (short for Sadistic, Intelligent, Dangerous, a VR amalgam of the most violent serial killers throughout history) causes Donovan to go into shock, killing him. The director overseeing the project, before Commissioner Elizabeth Deane and her associate, William Wallace, orders the programmer in charge of creating SID, Dr. Darrel Lindenmeyer, to shut down the project. Barnes is a former police officer imprisoned for killing political terrorist Matthew Grimes, who killed Parker's wife and daughter. Barnes killed Grimes and innocent bystanders. This caused him to become a convicted killer and serve 17 years to life.
