In 1991,
robots are commonplace. When they malfunction and become dangerous, they are "runaways" handled by a division of the
police trained in robotics. Sgt. Jack R. Ramsay, a veteran officer, joined the "runaway" squad after an incident in which his
fear of heights allowed a criminal to escape and kill a family. After years on the job, he and his new partner Karen Thompson find themselves handling the first robotic
homicide. Investigating a household robot that murdered a family, Jack discovers strange
integrated circuits that override a robot's safety features and direct it to attack humans. These circuits are created from master templates, enabling them to be
mass-produced. Ramsay cannot learn anything from uncooperative informants who end up dead but eventually discovers that the perpetrator is Dr. Charles Luther. Luther, while working for a defense contractor, developed a program that allows a robot to
thermographically identify a human from amid cover and to differentiate between humans. Seeing the profit potential, he killed his fellow researchers and tried to sell the technology on the black market. A failed attempt to arrest Luther results in the recovery of another of his weapons, a
smart bullet: a miniature
heat seeking missile capable of locking onto a human target's unique heat signature. While investigating, Ramsay and Thompson find Jackie Rogers, who was once Luther's lover. She double-crossed him and stole the circuit templates, intending to sell them. When they create a ruse to transfer Jackie to safety, Luther attacks the police convoy with robotic
smart bombs. They discover that the bombs are zeroing in on a bug in Jackie's purse and throw the bag out the window before a bomb reaches the car. Ramsay decides to make a public appearance with Jackie at a restaurant to draw Luther out, but instead Luther captures Thompson and wants Ramsay to exchange her for Jackie and the templates. Before making the exchange, Jackie gives some templates to Ramsay for insurance that Luther will not kill her. He kills her anyway after discovering the templates missing. To retrieve the missing templates, Luther plans to attack Ramsay. He uses the police computers to discover everything about Ramsay's personal life, including his son Bobby. After discovering that his information was hacked, Ramsay races home to find Bobby missing. Luther calls to confirm that he kidnapped Bobby and wants to exchange him for the missing templates. Ramsay agrees to meet Luther at an unfinished skyscraper. Luther gets the templates while Ramsay sends Bobby down in an elevator. "Assassin" robotssmall, spider-like robots that kill by injecting their victims with acidare waiting to kill the first person exiting the elevator. Thompson arrives and helps Bobby stay out of reach of the robots. Furious, Luther begins firing smart bullets, but Ramsay turns on the robotic construction equipment, creating heat sources that cause the bullets to miss. Ramsay attempts an escape downward on the elevator, but the elevator malfunctions, speeding up to and stopping on the very top. Ramsay is forced to overcome his
acrophobia by locating a reset switch underneath to restart the elevator back down, whilst encountering and defeating 3 robot spiders. He succeeds, but encounters Luther again. During a confrontation, Ramsay and Luther fight, but Ramsay gains the upper hand by stopping the elevator. The abrupt stop catapults Luther onto the ground, in the midst of his robot spiders. Programmed to kill whoever came down, the robots rush Luther, repeatedly injecting him. After helping Bobby down, Ramsay approaches Luther. Screaming, Luther reaches up to grab Ramsay, but falls back, dead, while the spiders self-destruct. Ramsay and Thompson kiss. ==Cast==
