The entire film is styled as a homemade recording, starting with Uday arriving at Ragini's house. When he inquires about their destination and receives no reply, Pia, Ragini's friend, becomes upset and insists that Uday leave immediately. However, Uday disregards her protests and proceeds to wake Ragini, urging her to prepare for a weekend escape. The characters set off to what is described as Uday's "house"—a mysterious, abandoned building situated in a remote area. During this time, Ragini's mother calls her to check her whereabouts, but Ragini lies and disconnects the call, hinting at secrets she wants to keep.
It is soon unveiled that Uday is involved in a sinister business of filming and selling sex tapes of innocent girls. This particular time, Ragini believes Uday is genuinely in love with her, which deepens her trust and vulnerability. As their romantic plans escalate, they are interrupted by [Pia] and her boyfriend Vishal, who come over unexpectedly. Uday quickly becomes angry and demands Ragini to dismiss the visitors; yet, Pia and Vishal decide to stay for a while, leading to tension and suspicion.
Vishal, curious about the history of the house, asks Uday about a woman who lived there before—a woman rumored to be called a witch by her own family. According to Vishal's story, the family murdered her, and since then, her spirit has haunted the house, killing those who enter. Uday dismisses this story with laughter, but Vishal remains uneasy. As Vishal ventures further inside, he senses a presence behind him, and soon after, there's a knock at the door. When Uday opens it, Vishal stumbles in, visibly wounded, as if fleeing from something terrifying. The atmosphere thickens with fear, prompting Pia and Vishal to leave in a panic.
The situation intensifies when Uday activates security cameras without informing Ragini and handcuffs her to the bed. They are moments away from intimacy when Uday is suddenly yanked by his hair, and he begins to investigate strange sounds, claiming, "I am not a witch." His behavior becomes increasingly abnormal; he returns visibly frightened and paranoid. During the chaos, Uday accidentally exposes the camera filming their affair, which terrifies Ragini and sparks her outrage.
Uday's mental state deteriorates rapidly. In a state of panic, he attempts to unlock Ragini's handcuffs with various objects, eventually grabbing a pointed item and stabbing himself in the neck, leading to his death. Ragini screams for help but finds herself alone with no assistance. She desperately searches the house and tries to free herself, using broken glass and her own blood as lubrication to cut her hand and escape her restraints.
Despite her efforts, she is unable to open the doors, which repeatedly swing shut. Her screams attract some passersby, but they are unable to help her. Ragini is eventually dragged into a closet where she finds a dead body—later revealed to be Vishal's. She manages to escape in a frantic run to her car, breaking the window to pull Vishal's corpse out. However, the vehicle won't start, and she runs into the jungle to hide, discovering Pia's dead body along the way. Eventually, the vengeful spirit drags her back into the house, hanging her from the wall for days.
The film concludes ambiguously—left open to interpretation—showing Ragini unconscious, having undergone psychiatric treatment for ten months. The story's ending serves as a stark warning to naive young women about the dangers of trusting shady individuals and venturing into dangerous situations. The narrative emphasizes a haunting motif that blurs the line between reality and the supernatural, capturing the audience with its unsettling atmosphere and relentless suspense.
