When a film crew sets up in a deserted psychiatric hospital with a mysterious history to film a low-budget horror movie, they encounter more than they anticipated. The late hours and sleep deprivation start to affect them, and as their work continues, the damp, decaying structure appears to awaken, drawing energy from its new occupants. As the production progresses, the crew members begin to act more bizarrely, prompting the remaining rational individuals to understand they must escape before they too fall under the building’s eerie influence. However, the ancient hospital seems unwilling to release them.
