丈夫失踪十年,寡妇阿福含辛茹苦将小叔子赵天宝养大,供成村里唯一的大学生,可他却装瘫痪,连同女友一起欺骗嫂子的家产,却不料瘫痪是真的,阿福辛苦凑钱为其治病却遭到小叔子的冷眼相待,甚至还要将其赶出老宅。失踪多年的赵天勤强势回归。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. The watchman (Sabeer Masani) is being terrorized, one of the residents Sanjay (Fardeen Khan) is behaving erratically, and a murder occurs. Inspector Liaqat Quereshi (Nana Patekar) is sent to investigate the murder at the building. All the while, neither the psychiatrist nor the exorcist makes much progress with Swat。
