Brother and sister Seth and Angelina live a secluded life in their family's beautiful Beverly Hills mansion. But these upper class siblings share a dark and violent hobby of using sexually driven 'party lines' to meet and lure lustful strangers into a deadly ménage à trois, the climax of which is a razor slash to the throat! With the victim count steadily rising, Detective Dan is under the gun to crack the case, but when his girlfriend falls prey to the maniacal duo, Dan goes rogue, taking his own violent measures to dispense justice. Juxtaposing a slasher film setup with police drama and erotic thriller plot points, William Webb's PARTY LINE is a forgotten oddity, bridging the late 80s slasher craze with the soon to rise early 90s 'skinemax' obsession. Starring Leif Garret (Devil Times Five), Shawn Weatherly (Baywatch), Richard Roundtree (Shaft), and Richard Hatch (Battlestar Galactica) and stylishly photographed by renowned visual effects cinematographer, John Huneck (The Terminator), Vinegar Syndrome brings PARTY LINE to Blu-ray for the first time, newly restored in 4k from it's original 35mm negative.
