1970年代末,在西北敕勒川牧场做了小半辈子牧马人的小学教师许灵均(朱时茂)一路风尘来到北京饭店,与30年未曾谋面的父亲、旅美华侨企业家许景由(刘琼)见面。当年,追求个人自由的许景由无法忍受与妻子的错误婚姻,丢下妻儿去了美国。此次归来,他有心带许灵均回美国继承事业。
交谈中,许灵均不认为将自己融在集体中、时时以国家利益为重的行为是思想陈旧的表现,对于父亲的舒适生活,他并不艳羡。
回顾自己几十年来所走的道路,虽有幼年成为弃儿、青年被打成右派下放牧场的悲惨经历,却也数次从牧区质朴、善良的乡民身上感受到人间温情,而在艰难岁月中与四川苦命女李秀芝(丛珊)结为夫妻后,许灵均更是尝到苦尽甘来的心酸与甜美。他认为,国家在好不容易迈过“文革”这个大坎之后,个人更应该同亲朋一起,不离不弃地跟着她走向新生。。五位素不相识的年轻人,意外进入了怪兽横行的时空。他们面对的将是一场屠杀盛宴。在一个充满了不可思议的能量矩阵的结界中,他们五个人似乎进入了一场无限循环的生死杀戮游戏。深处密林中的每个人,似乎都在被监控之下。要想逃出生天,拯救自己,他们需要异兽的帮助,他们似乎又要躲避异兽。。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。
