Back-to-back murders happen in a mansion to anyone who tries to purchase it. The senior Police Officer is left helpless after its owner's death and asks Commissioner Verma about the tale of the mansion from 20 years ago when he was posted in the village as an Inspector. Verma tells them about two lovers, Suraj and Nisha, who loved each other but Thakur lusted on Nisha and on their wedding night Thakur killed Suraj and Nisha committed suicide, and it's her spirit that haunts the mansion even after 20 years. Thakur's daughter Kiran returns from London and introduces her husband to Thakur, who is shocked at the man's resemblance to Suraj--and that his name is Suraj too. Nisha's spirit waits for Suraj and wants to unite with him. On the night of the new moon she inserts a nail into his leg and he remembers his past life. Nisha must insert another nail in Suraj's other foot on the next new-moon night, but Kiran won't let her husband surrender to Nisha's spirit.
