In Diya Aur Baati Hum, Bhabho is adamant on her stand of marrying Sooraj (Anas Rashid) to Lalima. Babasa tries to make Bhabho understand, but is in no mood to listen. Bhabho, who just wants Sooraj's happiness that he couldn't get from Sandhya is ready to hide his unstable condition from Lalima.
Lalima, who meets Sooraj, is happy that the latter praised her ladoo. Bhabho is happy with the development. Bhabho puts Sooraj's marriage proposal for Lalima, but Lalima's brother rejects.
Why did Lalima's brother reject such good proposal? Did he know about Sooraj's health condition? Or was it brother-sister sentiment that's holding him back?
On the other hand, Sandhya will be seen selling jaggery as told by Manjari. Few men fall behind Sandhya aka Sagarika (Deepika Singh) whom Chandu aka Shekar calls as landlords. Chandu asks Sandhya to run as they won't spare her.
Sandhya, at a point, stops as she finds no way to run anymore. The man who had followed her with tractor asks her to shoot him by throwing the mobile. Sandhya tries to shoot but drops the gun as she wasn't able to handle. Seeing Sandhya losing it, Chandu comes to her rescue.
All these incidents will be pre-planned by Chandu to test Sagarika's real identity. Sandhya, who knew that she was being tested plays cleverly and escapes this time too. Previously, Chandu had asked Sandhya to run away from Manjari and the village, but Sandhya returned back as she lost all money because of a thief, who helped her indirectly to return back to the village.
Chandu tells Garjana men that he has been unsuccessful in knowing Sagarika's identity and he plan one more but last test, which will definitely reveal Sagarika's identity. What is that test? Will Sandhya reveal her real identity?
