Review by lost-in-limbo

You feeling lonely, well pick-up the phone call the "Party Line" to live-out you undesirable fantasies as you can talk, or just listen and then maybe hook-up on this single-dating service line. The concept abound can really touch a nerve, because how authentic it is and how a fad so popular and addictive could spin dangerously out of control in not knowing what you're really getting in to. This gimmick is what drives the story, but the low-budget produced "Party line" is something fairly patchy and trashy, as it falls somewhere in between a detective film and seedy slasher outing, and when it's focusing on the former it's quite stodgy but with the latter it's rather riveting… as eventually the two would tie in together.

Two disturbingly crazed siblings (who have a very strange, perverse relationship); like to participate in a chat hot-line, luring their eventual victims to meet up with them. A well-worn, rogue detective happens to come across one of the sibling's murders and then is reluctantly assigned to the case with the aid an aspiring, by the book female assistant of the Distract Attorney.

Whenever the story was dealing with the brother and sister relationship, it brought up some kinky and demented shades of jealousy and affection. Even the past events of their parents intrigues (especially one scene involving Garrett and a wedding dress) -- as this could be the attribution to their murderous impulses, but the script only window-dresses it by never truly balancing it out. Leif Garrett plays it cold, but underneath that persona he's feebly unstable in his fear of being alone as a meek mummy's boy but he's overshadowed by the formidably headstrong, but racy Greta Blackburn. However the sub-plot involving the hard-bitten detective (who wants to be like Eastwood's dirty Harry --- as just look out for the movie poster of "Sudden Impact" in his home) and Distract Attorney assistant is simply black and white. These moments in the film are laboured, despite the best efforts of Richard Hatch and Shawn Weatherly. Also showing up in nothing but a minor role is Richard Roundtree. The script keeps a serious tone throughout, but can go over-the-top and cause some giggles with unusual developments, contrived circumstances and a rushed wrap-up. The direction is predictably textbook looking like a made for TV feature, but killing it is the sluggish pacing and working its way in is an oozing jazz flavoured score.

Watchable, but token stalk n slash thriller at best.
