"Altar" (also known as "The Haunting of Radcliffe House") is a 2014 British horror thriller film.
Plot: Renovation expert Meg Hamilton, her husband Alec, and their two children, Penny and Harper, move into a large, dilapidated country house on the Yorkshire Moors. Meg's task is to restore the house to its original Victorian grandeur. However, after losing two renovation teams who were too superstitious to continue, she is forced to carry on alone. As they delve into the house's past, discovering secret rooms, a Rosicrucian mosaic, and experiencing numerous unexplainable events, the Hamilton family gradually becomes convinced they are not just restoring the house, but also awakening its original Victorian owners who died 150 years ago. Before they can escape, the house and its former occupants trap them, forcing them to spend one last, terrifying night under its roof.
