Diya Aur Baati Hum's July 18th episode: Three months have passed after the family gets the news of Sandhya’s death. Bhabho changes a lot. She becomes strict with her sons and daughters-in-law. She warns Meenakshi never to dare cheat her.
Sandhya’s boss motivates her to forget her family and concentrate on her mission. Still she recollects the sweet bonding she used to share with her near and dear ones. She is sent to a Kali Temple where she is to go as Sagarika Das.
The Chief tells Sandhya that the members of the Garjana organisation will come there. They will be informed about her presence and they will abduct her for interrogation.
Sandhya has to take every step with immense caution, warns the Boss. He also adds that the Garjana people are much more powerful than the policemen; so, the police department has to fight against them in a shrewd way.
The Garjana Boss trains his men to fight against the police. He tells them that the police is their enemy. He says that Himanshu’s death has caused a big loss of funds. An informer of police cleverly spreads the news of Sagarika’s arrival at the temple.
The Garjana Boss is informed that Himanshu’s fiancee Sagarika Das has come to a Kali Temple to pray for the soul of her dead father Shantanu Das. The Boss is surprised because he knows that Sagarika was in the same compartment with Himanshu.
The Boss tells his subordinates that Sagarika must have vital information about Himanshu; so, she must be caught and interrogated before the police can catch her. Sandhya comes to the Kali Temple, as per the plan.
