If a film crew goes in to an abandoned psychiatric hospital having a past to shoot at a low budget horror film, they get a lot more than they bargained for. Lack of sleep and the late nights begin to take a toll, and the longer this team works, the more the humid, moist construction seems to be coming back to life, feeding its brand new inhabitants. As the fire wears on, members of the team display increasingly odd behavior leaving those still sane realizing they need to get out of the place until they too succumb to the construction's infectious hold, the single real problem, the old hospital isn't ready to allow them to go.
