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 Sandhya. 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”.
Dr. Anand is about to inherit a large fortune from a distant relative under the condition that he is perfectly mentally stable—otherwise he would not inherit the property as there had already been cases of mental instability in his family in the past. His colleague, Dr. Lata loves Dr. Anand but he already has a girlfriend, Seema. Mystery unfolds when Seema is killed by a cyanide injection and the suspects are Dr. Lata and her father, Dr. Singh, the head doctor of the hospital in which Anand and Lata work.
