Coffy is a nurse by day and avenging angel by night. When she discovers that her little sister has been doped up - and freaked out - by a greedy drug pusher, she not only puts an end to his miserable days, but she vows to follow his trail of corruption up to the top. But what Coffy doesn't realise is that all is not what it seems - and that the leafy green behind the pushers' scene just may come from someone she knows.

A triple bill of sci-fi cops. 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.
