Werewolf Massacre at Hell's Gate

A witch who's burned at the stake places a curse on the small village of Skinner's Grove right before she dies. Several centuries later a paranormal investigator discovers a nest of werewolves in the town who are the hell spawn of the witch's curse. Moreover, a local militia and a young couple who find themselves stranded in the area in the wake of their car breaking down also run afoul of said werewolves.
