As the name suggests, there is indeed a woman in black in the whole movie. The purpose of this female wearing black is however not indicated at all. Once u see the whole movie you are rather left confused as to what is her purpose?
Daniel Radcliff, plays the role of an architect who is from London. He travels to a mashland where he is asked to re- design a house. Well what person in their right mind would want to spend his/her holidays in a hotel that’s on a deserted marshland?
However the story gets weirder when the main character finds out the truth about the lady in black and gets a shock when he is told that she haunts to get the kids of the village. The full story is that the female haunts because she lost her son to her younger sister. She too careless which lead to her son’s death.
Hearing this she suicides and takes the soul of her son with her. But still the point, why does she take the other children of the town with her is not cleared in the movie. This movie is not worth the time and money.
