[2] On a foggy night, Chandrashekhar, who is driving his car at high speed, meets with an accident.

When nobody answers the door, he enters the house and finds the dead body of a wheelchair-using man.

She tells him that her husband, Thakur Ranjit Singh, was a cruel man who used to mistreat his family and used to shoot cats and dogs with his gun for amusement (which is why nobody in the house woke up upon hearing the gunshot).

On this night, before Chandrashekhar arrived, they had an argument and when her husband threatened to shoot her, she tried to take the gun away from him.

Together, they fake a robbery so that Ranjit's death appears to be case of a theft gone wrong and more importantly, to suggest that the murder happened at a different time and give Rani an alibi.

Some of the important evidence they find at the crime scene is the dead man's pocket watch, an empty cigar container, and a tea tray which has fingerprints of an unknown person.

Police soon find out that the cigar container and fingerprints belong to Suresh Saxena, a prominent lawyer and a friend of the family.

But upon enquiring, the police find out that Suresh had received a phone call from a woman and had subsequently left the party for about an hour.

On the night of the murder, Ranjit got into a furious argument with Rani and threatened to destroy Suresh's budding political career by exposing his affair with a married woman.

At the trial, the public prosecutor explains that the love affair between Suresh and Rani was the motive for the murder.

The prosecutor tells the court that Suresh was present in the house at the time of the murder (the phone call and his disappearance from the party for an hour, during which the crime was committed).

Ranjit had a lustful eye on Kiran and out of jealousy framed Chanrashekar in a false case and had him imprisoned for 5 years.

He approaches Ranjit's house under the pretenses that his car had an accident and he wants to use the phone but in the process really to recover his wallet.

To his surprise, he finds Rani with the gun in her hand and ready to take the blame for the murder.
