As Prakash reaches the venue, he is introduced to a motley group of people, all gathered there for the old man's big day: his son, his reticent brother, a dignified middle-aged lady who once owned the bungalow, a listless lawyer who manages his legal affairs, a mild-mannered young man who works as his secretary, his beautiful, young biographer and his mysterious friend, who has never lost a game of chess to him. As the storm lashes on through the night, one of the people in the bungalow is murdered ! in a game of cat and mouse that follows, Prakesh soon finds out that under the surface of apparent warmth and friendliness, nothing is as it seems and that the bungalow holds one shocking secret after another !.
