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。在地产霸权、官商勾结、贫富悬殊.成为主旋律的社会,有人选择沉默,有人执意抗争。辍学硕士生朗(关楚耀 饰)胁持炸弹械劫银行,打算控诉社会劫富济贫。不料出口被意外炸毁,朗与人质──因眼疾而事业止步的警探健豪(黄贯中 饰)、职场情场上埋没诚信的银行职员韵怡(谢安琪 饰)、痴心错配的失婚贵妇Rebecca(陈美琪 饰)和诲人不倦但被时代淘汰的退休教师德叔(泰迪罗宾 饰),被困俨如密室的银行。五段浮城哀歌相互交织,令案件何去何从?这五个一触即发的炸弹,将成为重新出发的新起点,还是使他们走上命途终站?。
