Inexplicable murders in the Catskills. A Hooverville of squatters plummets into a gigantic sinkhole during a ferocious thunderstorm, where their bodies are torn apart and devoured as if by some pack of wild animals. Arthur Munroe, a journalist at the scene, follows a trail of legends to an abandoned Dutch colonial mansion at the top of one of the nearby mountains. And soon discovers and experiences the lurking fear.
