With an all-star cast, including Tom Sizemore, Ja Rule and Danny Trejo, Furnace goes deep inside the walls of a maximum-security prison.
When a number of brutal and suspicious deaths occur in and around the prison, detective Michael Turner (Michael Pare) is brought in to investigate.
But what begins as just another suicide investigation quickly unfolds into a furious and frightening struggle to uncover the unexplainable, while escaping death at the hands of a vengeful spirit unleashed within the prison walls.
