From the producer of The Devil's Rejects. Back in the 1970s several patients in an experimental sleep study reported seeing shadowy intruders. These patients - and hundreds of others - died in their sleep soon after. Doctors called the phenomenon 'Sudden Unexplained Nocturnal Death Syndrome'. They refused to discuss the shadows. Now a struggling late-night radio host (Dallas Roberts of The Grey and Rubicon) and a sceptical CDC investigator (Alison Eastwood) have begun researching a disturbing new outbreak of shadow sightings and sleep fatalities. Could this be a case of paranoid hallucination or are these victims literally being scared to death by actual nightmare creatures? Anne Dudek (Covert Affairs, House M.D.) and Mariah Bonner (The Social Network) co-star in this supernatural thriller based on true events documenting the authentic existence of SHADOW PEOPLE.
