Woh Kaun Thi?

On a rainy night, the highly reputed Dr. Anand is driving. He sees a woman standing in the road and gives her a lift. She introduces herself as No one. As soon as she steps in the car, the wipers eerily stop working. He's even more spooked when the lady shows him the way when it isn't visible and guides him outside a cemetery. On reaching the cemetery, the gates open automatically and he hears someone sing the words "Naina Barse Rimjhim Rimjhim".
