In the latest episode of Naagin 4,
Dev rebukes
Brinda for killing his family members. He is upset with her but she asks him to come to the 'mandir' with her. Dev refuses to. A storm leads Brinda to land in the temple where she asks Shiva why she has been called there.
The story shifts back to the past three days when Brinda had assumed that it was Dev who had killed her mom.
She decides to take her revenge by killing Dev in the middle of the night.
Just then, she recalls how someone was thanking Dev on March 8 for being with him. She wonders if Dev is innocent and Vishakha behind the murder of her mom. However, she rules out even that because Vishakha was with her. Brinda suddenly finds Milly, who has been killed by someone, thrown into her arms. Before dying, Milly tells Brinda that she'd find the truth at the Lal Tekdi mandir.
Dev comes there and blames Brinda for killing Milly. This confuses Brinda as she had seen him wearing a raincoar and a hat. It is learnt that it was Shalakha who had insisted Dev to change the attire. Shalakha tells this to Mundika and tells her how she managed to kill Milly and put the blame on Brinda.
Dev accuses Brinda of killing Milly and tells her he will call the police. She tells him that she hasn't killed Milly. He gives her 24 hours to prove herself innocent. Meanwhile, the police are called for investigating into the matter.
The police try to match fingerprints of everyone in the house. Brinda's do not match and neither do Shalakha's. Just then Shalakha finds bloodstains on her saree and hides it.
After the police leave, Brinda is again accused by Dev for killing Milly. She tells him she still has 24 hours to prove herself innocent. Shalakha overhears them. Later, the three of them are seen in a car. Brinda realises she would have to turn into a Naagin to increase her powers and learn the truth.
When they reach Brinda's house, she confides in her mother. Brinda and her mom begin to find the sandal that the former had envisioned in all the bags. Shalakha, meanwhile, looks for the half locket that is missing. The servant informs Shalakha that all the bags are with Brinda.
Mundika manages to get Shalakha's sandal out of the bag. Brinda's mom asks her to turn into a Naagin and see the rest of the truth. Brinda does so. She is about to leave the house when Dev crosses her path. She tells him to pick her call later.
Elsewhere, Shalakha asks Mundika to find her missing locket. When the latter refuses, Shalakha tells her she knows Mundika is Vishakha. Left with no option, Vishakha leaves to find the missing locket. Meanwhile Brinda goes to the place where Milly was killed to find the missing locket, sandal and the owl.
