Out For Blood
Synopsis?

Not long after the turn of the twentieth century Physician Thomas Martins had created a formula that when injected into the base of the skull gave the recipient extended life and amazing regenerative powers. How long the life extension was has never been found out, as none of his followers had yet died of natural causes; due to the continual regeneration of their cells. The formula however didn’t come side-effect-free, two major flaws were discovered by Martins, but only after he had been injected with his formula.

His followers whom he labelled his “Collective” were offered the injection by Martins but were not told of the flaws that came with it. The first of these flaws was fear of water; fear because if they touched it, it burnt them. And getting caught in the rain was fatal for them. The second of these flaws was even more aberrant; it turned them into drinkers of blood, not Vampires that couldn't go out in daylight, nor did they have pointed teeth, and they dont' turn into bats at night and fly around looking for victims. However there are victims , and these victims they take from the streets of nearby towns, all young, and all female.

After a ninth young girl goes missing in Richmond Virginia, one of the mothers Ellie Vincent who is a stripper, hires two Private Investigators, Larry Kessler and Gregg Pierroni to find her daughter. While Gregg is on the case he himself mysteriously disappears after following a lead given to him by a Psychic, a Psychic who has her own agenda where the “Collective” are concerned.

Vicky Meredith and Jill Gordon are two nineteen-year-olds who get entangled in the mayhem when they accidentally run over Gregg as he is trying to escape his pursuers. All three are then taken back to town and locked in a cell where they undergo a night of horrific proportion with Vampiristic overtones. A storm begins to move in over the town causing panic among the “Collective” as they try to repair the damage caused to them by Gregg in his earlier efforts to locate the missing young girls.

Larry Kessler and their secretary Brenda Wise are worried for Gregg and decided to pay the Psychic a visit. Whilst there they are told of a story so fantastic they find it hard to believe themselves. Under duress the Psychic agrees to help them in their efforts to find Gregg, in the process she discovers that the “Collective have taken her daughter as revenge for her part in trying to destroy them months earlier. Along the way to the town where Gregg and the others are being held Larry and Brenda become separated, Brenda soon finds herself in mortal danger and realises there is no way out for her.

Gregg and Jill eventually manage to escape from the cell but won’t leave town until they have rescued the girls that are fortunate enough to still be alive. They are helped by a very lost Pyrotechnician called Nick Demby from New York, he was on his way down to Cleveland for a Science Fiction Convention but ran out of fuel just a half mile out of town. When told of their situation Nick couldn't believe his sci-fi luck. Together the three of them bring the story to a heart-racing and explosive fuel filled ending.
