The first film, 'Robocop', is set in the near future and Detroit's soaring crime rate is unsuccessfully policed by a corporation which plans to build a new city, if its workers can go about unmolested. When its new 'enforcement droid' proves unworkable, a murdered cop (Peter Weller) is wired into a computer-controlled titanium body and set to the task at hand.

Unimpressed, 'Robocop' seeks vengeance on all sides in this violent but often funny tale. In the second film, 'Robocop 2', a new model, Robocop 2 (Tom Noonan), is built while Robocop 1 still patrols the streets of Detroit. Robocop 2 is given a maniac's 'soul', thereby setting the stage for a showdown between the two computer constables.

Finally, in 'Robocop 3' Robocop is befriended by a young girl whose parents have been killed, and after his partner is killed by the head of a private security firm, he joins a group of rebels to fight back against the evil businessmen. There is a notable fight sequence between a plastic-like robot Ninja and the sluggish metal Robocop, which, together with the rebels hiding out in the derelict General Motors Factory, constitutes a thinly veiled critique of the Japanese car industry from the heart of Detroit - the original motor city.
