One night at Shanti Nivas, a mental asylum, a man is found murdered near one of the cells. The victim Tipu, was an attendant at the asylum, who had stolen a patient Drishti's necklace before he was murdered. When his partner finds his dead body, he sees a shivering Drishti sitting next to him with a bloody knife in her hand. The next morning, as Drishti is accused of murdering Tipu, the nurse at the asylum seeks K.D. Pathak's help, knowing that Drishti is innocent.
