A grotesque brougham stops in a dark forest and its cowled driver, Lalbai the sorceress, beckons to the bewitched passenger, a newlywed bride. Lalbai leads the bride to the Shaitani Ilaaka (devil's domain), where she is roused from her spell. The bride is sacrificed, screaming and kicking, at the altar of her aka Shaitan, an ancient and fearsome demon. Years ago, he roamed free and indiscriminately terrorized the local townsfolk. But he was ultimately defeated, reduced to a formless soul, and held, by a magic charm, to remain imprisoned forever within the Shaitani Ilaaka. Lalbai brings him a fresh bride every Amavasya night. Shaitan consumes the blood of this bride, and grows stronger with each offering, until he can break the charm, restore all his evil powers and ravage the world again.

A few years later, Anju grows up into a beautiful young lass and is in the final year of her university. Roma notices her girl in love with a decent guy Deepak. He is the only son of an industrialist and is a well-cultured young man. Deepak gets to know of Anju's problem and contacts a tantrik through his parents. The tantrik is none other that yogi baba, dr. Yograj's guru from Tibet. He visits the thakur palace and instantly spots the root of the problem. He asks deepak to remove Anju from there and take her to the famous Pavankhind mandir beyond a mountainous region in the city. He also insists that they leave during the bramhakaal, during which all evil beings are powerless. It lasts for 9 minutes at the break of dawn. All friends come together and hiring a bus, help Anju to wear the bramhakaal taaveez, which tantrik baba himself has purified with the most powerful prayers. Baba warns Anju that she should never in any way, remove the taaveez from her neck. Roma leads the kids outside. But Shalaka arrives just then and is outraged at Anju's removal. She steps way out of line and demands to know Anju's whereabouts. Roma refuses and puts her in her place, whereupon Shalaka transforms into a hideous witch, Lalbai, and reveals she has served Shaitan for ages, and when Thakur's ancestors used various magic incantations to defeat Shaitan, she infiltrated Thakur's household as a governess. She hopes to use Anju, the living descendant of Shaitan's enemies, as the final sacrifice to liberate Shaitan. Roma is shocked to find her maid in such a ferocious form and shoots her with a gun. But Lalbai, who is already a possessing evil spirit, pounces on Thakurain and murders her brutally.

Deepak and Anju are just crossing the backyard when Lalbai again comes there and tries to stop them. She tells them her real identity and attacks Anju, who falls in the swimming pool. Deepak tries to free her and gets wounded. Just then baba arrives there and imprisons Lalbai, helping them to escape. Deepak and his friends successfully remove Anju to a safe haven away from the city. They take the opportunity for some rest and relaxation. But in the old cafe, local ruffians find the girls at a table and start harassing them. A guy then reaches there and pounds the goons along with Deepak and Abdul, making them flee. He introduces himself as Kamal and befriends the whole group. Reaching the old fortress, they light the diya there and Anju feels a strange peace surrounding her. She gains her happiness back for some time. Baba asks Deepak and Anju to get married there, as Lalbai won't be able to harm Anju after they consummate their pious union. Baba tracks Lalbai to the Shaitani Ilaaka. She now transforms herself into a wild eagle, to protect her remaining powers. He uses his spiritual powers to summon her. When he discovers her intentions with Anju, he swiftly realizes Deepak and Anju must marry and consummate their matrimony as quickly as possible. Deepak and Anju are deeply in love and would marry anyway, they hasten the event and obtain a marriage license with Baba and others as witnesses. But while Deepak's sister is alone in the mandir preparing the flower baskets, the
