Based on actual accounts of werewolf sightings in Walworth County, Wisconsin, the film follows a local sheriff who is finally forced to accept that a string of horrifying deaths is linked to a predator which possesses DNA of both man and wolf.
The new Sheriff, Phil Jenkins, (Jeff Denton) and his first assignment is a missing person case on a woman who disappeared -- on the night of a full moon. When a slew of reported sightings from the townspeople of a reported monster in the area start flooding in, Quinn McKenzie, (Thomas Downey) a crypto-zoologist, comes in to offer his help with the investigation. He believes that the creature being 'sighted' is a werewolf, which Phil isn't too keen to believe. When enough evidence is unearthed for Phil to finally accept that the killer may indeed be a werewolf, like any good ole sheriff, he takes a posse armed towns-members into the woods to hunt down the creature.
This is certainly one of your more vicious werewolves, as this one maintains its human intellect and takes the time to 'select' its prey.
