Next day the wife comes late from office but the husband accuses that she is having an extra marital affair and starts beating her, the made stops him and threatens him that she will file a complaint in police station. The husband then plans to silence the maid forever.
Next day, police is searching couple's house. Tarun (Husband) tells the wife(Veronika) that the necklace he gifted her is missing. Tarun tells police that he suspects Shanti (maid) and takes them to her home. Shanti's husband tells police that she is not at home but police accuse her of stealing. They find it in Shanti's house and police arrest her but Veronika bails her out.
At night, Shanti serves food to her kids and tell them that she needs to go out and will come soon. Kids and Shanti's husband (Raghu) are waiting for her but she did not return till late night. He decides to file a missing complaint.

He also tell them about Tarun beating Veronika and Shanti always trying to stop him, he says that was the reason Tarun accused Shanti of stealing the necklace. Raghu says no one came to their house in his presence and he don't know how the necklace came to their house. Kids inform CID team that Tarun's driver came to their house when the parents were out. Raghu also informs about Veronika giving bail for Shanti and Tarun threatening Shanti that she will pay dearly for this. Team have doubt that the driver must have put the necklace and Tarun might have murdered Shanti.

Daya sends Dushyant and Pankaj to get the driver and also notice Tarun's bad behavior towards Veronika. Veronika says she met Shanti last night and tried to give her money as Tarun removed her from the work, which Shanti denied. Daya doesn't believe in this story where husband accuses the maid of theft while wife bails her out and tries to help her. Veronika says Tarun will never kill Shanti and also defend him saying he loves her and never beat her. Daya and Shreya are angry on Veronika and Daya says they will soon know the truth from driver.

ACP sir, Sachin, Nikhil and Divya are enquiring about Shanti and one shopkeeper tells them that he saw her nearby, she was crying and one person was possible threatening her. The shopkeeper also says he was facing that man's back but that man seemed familiar with Shanti as he hold her hands while talking and also a cycle with milk cans was present at his side. Team wonders who this man could be.
In CID bureau, Abhijeet and Dushyant interrogate Tarun. He says he told driver to follow Veronika and when she went to meet Shanti, driver informed him so he left the party then saw the two ladies and left the place. At this time Dr Salunkhe enters and informs by the knife wound he thinks the murderer must be lefty. They ask Tarun to write address of places where he went and find out that he uses right hand.
Acp sir and team visit nearby dairy and the owner informs them that Raghu works for him to deliver milk. He also says that he didn't come for work as his wife was murdered. Team realizes this Raghu is Shanti's husband. ACP sir has a doubt about Raghu being the killer but couldn't get the motive.
At a mandir, Raghu meets a hooded person and cries. He says he did a big crime killing his wife and he must be punished for this and runs away from there.
ACP sir and team visit Shanti's house only to find it locked. A neighbor says Raghu left with kids just few minutes ago. ACP sir orders to put Raghu's photo in newspapers and tv channels and also ask control room for nakabandi everywhere. Behind team the neighbor lady smiles cunningly on this.

Abhijeet asks Raghu if he remembers the place where he killed Shanti. CID team brings him to the sewage line where Shanti's body was found but Raghu doesn't recognize the place. Team tells that this is the place where he killed Shanti. Raghu also shows opposite place than where Shanti was found. Team doesn't believe his confession. Raghu tells them how he used knife then strangled her and then gave her poisonous injection. At the moment Vansh says he is not feeling well and if he doesn't take the injection his health will deteriorate. Team asks Raghu to give injection to Vansh. Raghu is not able to hold the syringe. Finally, Abhijeet takes it from Raghu and says they know he didn't kill Shanti and he knows who the real killer is.
Raghu shows a big house to team. Few goons are present there. After some fight team catches the lady and she confesses she killed Shanti because she loved Raghu and he was not ready to marry her because of Shanti. She says she told to Raghu to confess about the murder or else she will kill his kids. (She is the hooded person whom Raghu met at mandir.)
