In an isolated brick mansion set amidst thick woods and mist, live Sandra Williams and her two children Sarah and David. Sandra's husband Major Frank John Williams is in the army and at war. There has been no news of him for a while.

The three servants, Mrs. Pinto (the nanny), Edgar (the gardener), and Maria (the helper), are employed by the Williams. The servants are strictly briefed about the quaint rules of the house and obey the orders diligently. They move around the house in soft steps and darkness adding to that sinister feel of the film.

Sandra feels that it is necessary to deal with the strange happenings in the house and goes to consult with Father D'Souza. On the way she is shocked when she runs into her husband Frank. Frank is in a dazed state and seems to be delusional. The family is thrilled on Frank's return. During the reunion of the kids with their father, Sarah shares a secret with her father that leaves Frank aghast. It is then that he decides to leave the house.

Frank with his friend Virendra take it upon themselves to get to the bottom of the mystery and intrigue, surrounding the Williams.

And after that?
