Danvers State Mental Hospital, closed down for fifteen years, is about to receive five new visitors. Gordon Fleming, the man who owns and operates the Hazmat Elimination Co, badly needs to win a contract to remove asbestos from the hospital. To seal the deal, Gordon unwisely promises that he and his crew can complete the massive job in only one week. Hazmat gets the gig and the following Monday their dangerous work begins. As the work week continues, the crew is drawn deeper into the mysteries that surround the asylum: rampant patient abuse, medieval medical procedures, and rumors of demonic possession. The hospital holds many dark secrets but then, so do each of the men. The longer they struggle under the grueling pressure of their job, the more likely it seems that one of them will crack. The question is, which one will it be?
