Collegian Ajay Sharma was born on 2nd April 1968 and lives in Bombay with his widowed mom, Asha. He is friendly with fellow-collegian, the wealthy Raj Sinha, and both often end up getting beat-up by goons and Madhu (Raj's girlfriend) respectively. After they graduate from college, Raj's maternal uncle asks Ajay to bring his birth certificate so that he could make his passport and find work for him in a department store in Canada. Ajay goes home to look for his birth certificate, but is unable to locate. His mother makes a show of helping him, but instead tears a document and tosses it outside. Ajay puts the document together and finds out that his real name is Ajay Malhotra, his father, Dr. Ravi Malhotra, is still alive, serving a life sentence in prison for killing and stealing a patient's organs. Ajay questions his mother and finds out that his dad was framed by the hospital owner, Rai Bahadur. He and Asha meet Ravi in prison and swear to avenge his humiliation.

After her husband, Ravi Malhotra, is killed, Sudha lives the life of a widow with her brother, Mahesh, and Bhabhi, Kamini. A new tenant, Ajay, comes to her rescue when she is molested by Bhavani's brother, both fall in love and decide to get married. Kamini initially opposes this match, but subsequently relents and both get married. Shortly thereafter she gets pregnant and it is then she finds out that Ajay is not who he claims to be, and may have been responsible for killing her husband.

The Sharma family re-locate to a semi-urban locality in a house that has a "reputation". The Sharma family consists of Mr. Sharma, his wife Shalini Sharma, only daughter Manisha Sharma or "Mini" as they affectionately call her; and their grandchild Bunty, as his parents had been killed in an accident. Strange things start happening, with a return of a dead kitten, and the brutal murder of Manisha's friend, Reshmi; an attempt to kill Mr. Sharma and Manisha's boyfriend, Deepak. What is the force behind these brutalities? Is it natural or supernatural?
