The longest continuously filmed paranormal investigation in television history, where five paranormal investigators are locked inside the legendary Pennhurst Asylum in Pennsylvania for two weeks to document unexplained recent reports of paranormal activity. Pennhurst is known as one of the most haunted locations in the United States, but recently, workers at the site have reported a sharp uptick in paranormal activity including mysterious noises and voices while others claim they were being physically attacked by spirits. Determined to get to the bottom of these claims, the owner has granted the team of investigators unprecedented access to the entire property including areas of the asylum that are closed to the public. The team will hunt the sprawling, spine-tingling property using their formidable skills and a wide array of top-notch tech gear to capture paranormal activity.
