Robocop: Set in Detroit sometime in the near-future, the film is about a policeman killed in the line of duty, who the department decides to resurrect as a half-human, half-robot supercop. The robocop is indestructible, and within a matter of weeks he has removed crime from the streets of Detroit. However, his human side is tortured by his past, and he wants revenge on the thugs who killed him.

Robocop 2: Still patrolling the city streets, RoboCop is scheduled by his creator, Omni Consumer Products, to be replaced by a new 'superior' model, RoboCop 2, that according to designer Juliette Faxx, will contain the human remains not of a cop but a criminal. In the meantime, an instantly addictive drug called Nuke is sweeping through Detroit thanks to a kingpin named Cain.

Robocop 3: In this second sequel to Robocop, the mechanical humanoid opposes the evil designs of his creators who have gone corrupt and are trying to take over all real estate in Detroit, kicking the poorer citizens out of their homes and turning them out into the streets.
