The paranormal investigators are called in to help a woman who saw a corpse floating in the Potomac River and then disappear. Clues provided by a local medium and town historian connect the report to the cold case of two murders decades ago. The team conducts a nocturnal paranormal investigation in the woods by the Potomac and uncovers evidence that indicates satanic rituals or witchcraft is being practiced in Shepherdstown. The team senses a darker entity in the woods, a feeling that's confirmed when the medium suddenly feels Bill's life is in peril.

The unusual activity subsided after wrapping the investigation, but when Chief King checks in with locals he hears about a disturbing uptick of hauntings nearby and fears Shepherdstown is one small piece of a bigger puzzle.
