Black Oak Investigations is a firm that handles office fraud, missing persons, and a variety of white collar crime. But Black Oak also investigates situations that are not so quite the norm as owner Ethan Proctor discovers when one of his operatives turns up dead in a town cowering in fear from something roaming the hills, leaving dead bodies in its wake.
