The story revolves around the demon
Ifrit and Auladhchakra, a
satanic cult in
Bangladesh aiming to perpetuate the bloodline of Ifrit. They used to kidnap women and summon a male demon to have sex with them so that they could be impregnated with the offspring of the demon. Professor Qasim Ali used to head a group of vigilantes that sought out the women impregnated by Ifrit, kept them captive until they gave birth, then immediately killed the demonic babies by cutting off their heads and sealing them within glass jars. This drew opposition from the villagers, despite their support, and the group was shut down due to its violently radical approach. Rukhsana is the daughter of one such woman, who was a victim of the satanic ritual but escaped her captivity before Professor Ali could kill her child. Arnab is a young man who owns and operates a printing press. Piyali, a nurse, is set for an arranged marriage with him. On the way home in the heavy rain, he and his parents accidentally hit an old woman. The woman dies, and when the police search her home, an old hut in the forest, they find a dirty Rukhsana chained inside. Arnab, feeling sympathetic and responsible upon realising she has no one, takes her in. Rukhsana knows nothing of the modern outside world and often sees demonic visions that frighten her. Arnab finds her strange but endearing. As the two spend time together, she falls in love with him. A mortuary assistant discovers that Rukhsana's mother has the cult's mark on her skin and informs Professor Ali, who has been searching for Rukhsana for years. One night, Rukhsana gets sick. Though Arnab mistakes it for her
period, the truth is that her body needs to spew out the poison it produces every month due to her demon blood. She secretly kills a dog by biting it and releasing her poison. She later admits that she loves Arnab, and the two make love. The next morning, Professor Ali confronts Arnab with the truth about her, but he refuses to believe him. The morgue assistant fights Arnab, injuring him. Rukhsana kills the assistant in retaliation and gets between Arnab and Piyali, feeling jealous. When Arnab argues with her, she grabs him by the throat and lifts him clear off the ground. Disturbed, Arnab realises that Professor Ali was right and researches about Ifrit. He learns that Ifrit babies are born in one month instead of nine. Arnab contacts Professor Ali. Just as he arrives with his men, Rukhsana reveals to Arnab that she is pregnant with his child. The professor's men tie her up and torture her so that she dies of her poison. Though she cries for Arnab, he leaves, depressed. After three weeks, Piyali visits Arnab at his parents' house, and he tells her the truth about Rukhsana. His conversation with her makes him realise he shouldn't have left her to die because it was he who impregnated her, and that it is his child. Rukhsana, after being beaten repeatedly, breaks free and kills the professor before heading over to Piyali's. She injures Piyali, but goes into
labour. Piyali is unable to kill her, being a nurse and with her past of having an
abortion. Instead, she helps Rukhsana deliver the baby, which has an
umbilical cord. Rukhsana leaves the baby with her and disappears. Arnab rushes to the old hut, where he finds her near death. He cries and hugs her. She resists the urge to bite him and release her poison, instead letting it remain inside her body. Before dying, she tells Arnab that their baby is human. At the end, Arnab says that Rukhsana's love made their baby human, rather than Ifrit's hatred. Arnab decides to take care of his baby then. ==Cast==
