After being abandoned for ten years following a failed renovation attempt and a mysterious death, work on Gateway Manor has started again, this time with the assistance of a television show called ‘Renovating Ruins’.

As work progresses, the secrets of the imposing mansion house are slowly revealed and an ancient evil which has lain dormant within the manor for centuries is disturbed and released, trapping everyone within the building. Members of the television show crew, assisted by a stranger with ties to the property must work together to stop the beast from escaping the walls of the manor.
