The beautiful Sanjana is a divorcee who moves to a hillside house, as she cannot afford a house in the city. To earn her living, she runs her stepfather's antique shop. However, it is not long before strange occurrences begin near and in her home. One day, a
Tibetan old lady gives her an antique
locket at her antique shop and leaves. Sanjana sells it to a tourist couple for
500 rupees. Sanjana finds the lady on the way to her home to return the money, but she discovers that the lady was dead. The locket is returned to Sanjana by the tourist as the Tibetan lady keeps haunting the couple to make them return it. Later, Sanjana is tortured and physically raped multiple times by an invisible demon, first in her room, then in the shower, and then in front of her own kids. Her dog becomes possessed soon after and attacks her and Vicky, her younger brother. Sanjana consults a psychiatrist who doesn't believe her, despite telling him multiple times. Soon, the invisible demon has sex with Sanjana, for which she gets an orgasm but soon regrets having sex with an invisible being. After a while, the demon takes away her younger daughter from Sanjana. She calls her psychiatric friend, and he brings a
parapsychologist. Sanjana comes to learn that the demon comes from an old well, where the tribals used to push down and kill criminals as punishment. Due to lightning striking the well, one soul who was a rapist was thrown in the well and killed; he has now escaped, and he fell for Sanjana. The parapsychologist opens the well from which all the evil spirits come out and attacks him. Sanjana jumps into the well to bring back her daughter. There all the spirits get combined into a huge demon. Sanjana throws the Tibetan locket to hit the demon, which then dissolves. The soul of Sanjana's father comes as an angel and returns her younger daughter. Sanjana prepares to leave her house, and suddenly the door closes. A demonic voice calls her, and she opens the door but finds nothing. Before leaving, her younger daughter suddenly runs to the house, and the door closes. ==Cast==
