Summary Sunil (Salim Shah) is married to Reba (Sujata Gokhale). Sunil is from a rich family, but his dad gives all his property to Reba upon his death. Reba is beautiful and smart. She learns how to run the business and how to drive a car. Reba is a control freak & uses her new independence to cut Sunil off. She pays off all debts, gives Sunil a fixed stipend of Rs 500 a month, tells him that he will be responsible for his finances henceforth, with no extra support from Reba. Sunil seems innocent but is constantly scheming to figure out how to get his father's estate back from Reba.

Sunil mentions to Reba that he has seen a stranger lurking around the house. The next day Sunil and Reba file a police complaint. The Inspector Ramani (Shakti Singh), knows Reba from before her wedding & promises police protection. Ramani has feelings for her & says that he feels Reba is punishing herself by being in the marriage.

Sunil goes for some errand that evening & returns home at 8 pm. Reba is worried about the stranger and the lack of police protection. At around 9 pm, Reba watches a man matching the stranger's description, lurking near her house. Reba is pondering her options & agrees with Sunil to ask Ramani for her father-in-law's pistol to be given to her. The pistol was deposited to the police upon her father-in-law's demise. Reba decides to get the license issued in Sunil's name.

Reba invites Ramani to her house at around 8 pm so that he can also see the stranger. Reba is alone with Ramani when she confesses that she feels that Sunil is plotting her death. She says she is staying only since her father-in-law wanted her to care for the estate. Reba has no love for Sunil. Meanwhile Sunil meets his servant Hukum Singh (Ramesh Goyal) in private and instructs him not to lurk around the house anymore as the purpose is achieved. Hukum works with his elder brother Mukund.

Once Sunil gets possession of the firearm, he meets Hukum Singh, gives him some money & instructs him to visit the house at 8pm (the usual time when Sunil returns home), knock the door, kill Reba, steal her jewels & run away. He promises him Rs 10,000 once he gets possession of Reba's estate. Hukum follows the instructions, strangles Reba, but then Sunil pounces on Hukum (as he comes out of the house) & shoots him dead.

Ramani knows Sunil has plotted Reba's death but has no proof. Ramani gets Byomkesh involved. Byomkesh writes a letter to Sunil stating that he has a letter from Reba from before her death & invites Sunil to meet him. He arranges for a tape recorder as well. But Sunil is smart & doesn't crack under counter arguments & pressures. He sees Ramani in attendance & accuses him of being the reason for Reba's death. In private, he confesses to Byomkesh that he killed Reba, because of her feelings for Ramani. As Sunil steps out, he is shot dead by Mukund Singh, brother of Hukum Singh.

Ramani admits his feelings for Reba. He says that they studied together, but Reba was from a rich family and was married off. Sunil got transferred to the same town as Reba and they started writing letters to each other. They didn't meet much.
