Vishal (Ajay Devgan), a stock analyst, and his wife Swati (Urmila Matondkar). The two are in search for a flat in Mumbai. Vishal finds the perfect place on the 12th floor of a high-rise apartment building. However, the apartment has a horrifying past. The previous occupant of the flat, a young woman had killed her child and jumped from the balcony and died. Swati learns about this incident shortly after moving in and becomes oddly fixated with the story. Then, a series of inexplicable experiences drive Swati to near madness. Vishal becomes helpless and convinced his wife has developed some sort of psychological disorder. He consults a psychiatrist, Dr. Rajan (Victor Banerjee). The couple's maid (Seema Biswas) believes Swati to be possessed, and calls in an exorcist (Rekha). Meanwhile, other seemingly unrelated events take place around the building.
