Plot
The illegitimate son of a rich man loses a court battle over the palatial house in which he has been living. So he appeals to Bangaru Muni (Sathyajith) and he sets off a devastating abhichara prayoga (black magic attack) on the legitimate son Mohan (Mohan) and his family. Bangaru Muni unleashes dakini, sakini, Mohini pisachi and other pretas in house. He does the ashtadig bandhan so that person should not escape.

Mohan lives happily with his wife (Jaimala), his two children, his sister Raasi (Pallavi), his brother-in-law Ashok (Veera Pandiyan) and his wife's sister Meena (Roshini). They all move to the palatial house. Mohan is an atheist who doesn't believe in the supernatural or God. Soon, the family is disturbed by a supernatural spirit unleashed by Bangaru Muni. The spirit in Mohan's body kills his wife, his children and his brother-in-law and even Bangaru Muni. Finally, Jolna Swamy (R. P. Viswam) comes to their rescue and fights against the evil spirit which is in Mohan's body. Jolna Swamy finally destroys the spirit, but Mohan is sent to a mental asylum, where he grieves for not believing in Almighty God.

Development
After the failure of his films Pick Pocket and Irumbu Pookkal, G. M. Kumar began work on his next film, also his first horror film. The film was produced by actress Pallavi's brother and another partner.

Casting
Mohan accepted the offer of the protagonist and hoped for a fresh lease on his career. Pallavi signed on for this new project with G. M. Kumar, who acted in two of his previous films. R. P. Viswam would have a vital role of a Swamy and was also responsible for the dialogue. The newcomer Arasavarathan would essay the role as Pallavi's husband, while Jayamala would play Mohan's wife. Three different cinematographers: K. Rajpreeth, Ilavarasan and Dhayal handle the camera, K. A. Balan was signed up as the art director, while A. P. Manivannan took up the post of the editor.

Filming
The film was made on low budget, G. M. Kumar shot the film with three different units, each unit consisting of an assistant director and a cinematographer: S. Govindaraj with K. Rajpreeth, S. Selvakumar with Ilavarasan and D. Narayanamoorthy with Dhayal. G. M. Kumar managed to complete the film within 12 days. The film did not include any fight sequences. Ilaiyaraaja provided mainly the background music and composed only one song. The film was heavily censored by the censor board, which gave the film an "A" certificate, an adult rating, due to its "mix of soft porn and hard horror".

Reception
N. Krishnaswamy of The Indian Express wrote, "The proceedings are sometimes terrifying, even repulsive, and are surely not meant for the soft hearted. Kumar resorts to a mix of soft porn and hard horror". Sundarji of Kalki wrote even though it is inspired from American films like The Exorcist, it is not the kind of building up fear slowly, its kind of horror standing behind the door and suddenly appearing. Therefore the initial fear in the beginning gradually becomes normal and becomes like that is it.
