'It happened, one night, just twenty years ago,' the aging caretaker said.
For the young traveller, seeking shelter from the unpleasant weather, it was happening right now. The haunting song-the knocking on the cupboard-the woman's figure, now here, now gone. All seemed reality. All that had happened two decades ago.
The caretaker knew all, told all. Anand, a youngman in love with Radha, Geeta, a beautiful girl so cruelly tortured by an almost inhuman sister-in-law. Dilip, the lecherous figure in society who cheated his men, and sold his women, Laxman, Madhu, Anand, Choudhury, Geeta, Dilip, Zarine, Radha. All so real. all so alive. Yet all entangled by the web that Dilip had diabolically spun twenty years ago.
This was the story the old caretaker had to tell. Incidents so strange to be well beyond the scope of normal proof or scientific investigation. Of a terrible revenge that struck back from beyond the bonds of this life. Of supernatural happenings beyond the understanding of mere man. Of incidents as strange today as they were twenty years ago.
This is the story too stark to be related in cold print. This is the story that perfectly merges with the colour, the sound, and the length and breadth of the motion picture screen. The story we tell today, of what happened those twenty years ago.
