In the near future, 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 the 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.
