chunk: In 2035, humanoid robots serve humanity, and humans are protected from the robots by the Three Laws of Robotics. Del Spooner, a Chicago police detective, hates and distrusts robots because one of them rescued him from a car crash, leaving a young girl to die because her survival was statistically less likely than his. Spooner's critical injuries were repaired via a cybernetic left arm, lung, and ribs, personally implanted by the co-founder of U.S. Robots and Mechanical Men (USR), Dr. Alfred Lanning.
