In the small coastal town of Potter's Bluff, a series of bizarre and violent deaths begin to occur, throwing the once tranquil community into a state of fear and suspicion. Visitors to the town are being brutally murdered in cold blood, with each gruesome incident increasingly confounding the local authorities. Sheriff Dan Gillis, a steadfast lawman and Potter's Bluff resident, takes it upon himself to investigate the spate of mysterious killings. As he probes deeper into the violent events, he is disturbed to discover evidence and incidents that defy logical explanation.

Sheriff Gillis' wife, Janet, grows increasingly distant and peculiar, adding to the Sheriff's personal angst and confusion as the boundary between reality and nightmare starts to blur. The town's coroner and mortician, Dobbs – who takes a little too much pride in his work – appears to be a helpful acquaintance, offering cryptic clues about the nature of the uncanny occurrences in Potter's Bluff. As Sheriff Gillis uncovers chilling connections and townsfolk he thought he knew reveal sinister dualities, the fabric of the community unravels, leading him to confront the nightmarish truth that threatens to shatter his world.
