One of the main characters is horribly disfigured as a result of a fire in his RAF fighter. The country home is decrepit and haunted. I gave up after a small child was apparently attacked by an otherwise friendly dog. Too much blood and creepiness for my taste. For others it might be an attraction.
Generally, British films are excellent but not this one. The ending left us wondering why they bothered to make it. Not engaging, not clear, bad ending.
