For their fourth big-screen outing the crew of the USS Enterprise abandon their usual 23rd century time frame for Earth in the year 1986. In order to save the planet from a rogue space probe in the future, Kirk (William Shatner), Spock (Leonard Nimoy), Bones (DeForest Kelley) and co must travel back to the twentieth century to find the only creature capable of communicating with it: a whale. The story is given comic treatment - Spock hides his Vulcan ears with a headband and poses as a burnt-out hippy, while the normally intrepid Kirk gets lost on a bus.

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.
