Autumn 1940, World War Two, the Blitz. Bombs are raining down, destroying the cities of Britain. The evacuations begin, and soon children are being removed from their families and taken to the country for safety. Teacher Eve Parkins is in charge of one such group. The children are scared and Eve does her best to calm them, but the truth is that she too is haunted by a personal tragedy she cannot put behind her. Their destination is Eel Marsh House. Desolate and forlorn, it is situated on a causeway and is sinking into the treacherous tidal marshes that surround it. Far from home and with no alternative, Eve and the children move in.

But soon it becomes apparent that there is someone else in the house with them, someone Eve can't see but who is far more deadly than any number of German bombs . The Woman in Black.
