Jenny Cooper (Charlotte Lewis), a beautiful English model living in Italy, dials a wrong number, connecting to a long-unmanned hotline for the lonely and suicidal; in doing so, she unleashes a reservoir of negative energy that follows her via the telephone and kills those around her.
As the above synopsis suggests, Dial: Help is a decidedly silly '80s Italian horror, full of ridiculous death scenes in which victims are choked by telephone cords (one woman is literally hanging on the telephone!), struck by coins ejected from a payphone, electrocuted by switchboard, and killed by exploding pacemaker. Even the fish in Jenny's aquarium aren't safe, the telephone in her apartment emitted a high pitched tone that sends them all floating to the surface.
Director Ruggero Deodato (of Cannibal Holocaust infamy) handles the craziness with style, using wind machines, lots of coloured light, an excess of smoke and plenty of neon (there is even one of those horrible '80s neon phones that tries to zap Jenny in the bath), but realising just how daft and consequently unscary the film's premise is, he resorts to getting Lewis into some sexy lingerie for the final act. Not that I'm complaining, of course: Lewis in black basque, stockings and suspenders just about makes up for her horrible wooden performance.
4.5 out of 10, which I might have rounded up to 5 if the character playing the jazz flute had died.
