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。抗日战争末期,厦门的一天黄昏,医学院学生何美纪正准备回校,在桥上遇到日军轰炸,急忙躲闪间,来自马来西亚的华侨实习生林志祥奋不顾身地上前紧紧抱住美纪,自己却被炮弹熏得满脸黑烟,志祥和美纪在等待轰炸过去的时光中互生情愫。他们相约,如果能躲过这场轰炸,明晚会在初次相逢的桥上约会。志祥所就读的学校突然宣布撤离,志祥因此没能赴晚上与美纪的约会。志祥撤离来到桥边时,取下自己胸前的名牌,放在桥边。晚上美纪到来看到志祥的名牌上沾满了血迹,心情非常难过,她担心着志祥的生死。战争结束后,在拥挤的火车战,美纪重遇志祥,看到志祥还活着,美纪心里又喜又忧,因为虽然她心里一直放不下志祥,但一切都已物换星移,人事全非,战争带给这对恋人却是永远的遗憾。。美国海军海豹部队在研究中心执行最高机密任务,然而科学家们陆续离奇失踪,还有其他生物伺机而动...。
