The "Jack" who's "back" in this contemporary chiller is none other than Jack the Ripper. The scene is Los Angeles: the time is August of 1988, exactly 100 years after the Ripper's original reign of terror in Whitechapel. When several LA prostitutes turn up murdered and disemboweled, young physician James Spader is accused of emulating Spring Heel'd Jack. Before the film is half over, Spader is killed, and so far as the police are concerned, the case is closed. But then, Spader's twin brother appears on the scene, determined to track down the genuine culprit (if it doesn't turn out to be him, that is!). Handled with restraint, Jack's Back covers much of the same ground as the classic Robert Bloch tale Yours Truly, Jack the Ripper, though its crucial plot twist is a tad more clever (if a bit silly out of context).
