The latest episode of Naagin 3 starts with Yuvraj (Vikrant) informing the family about Raavan dahan, and Sumitra (Rakshanda Khan) announcing that she has made a lot of arrangements.
The puja commneces and everyone gathers for Dussehra celebrations. Bela (Surbhi Jyoti) tells Yuvraj that she will kill Maahir (Pearl V Puri) during the celebrations.
Meanwhile, panditji asks Maahir and Bela to perform the puja. Sumitra, on the other hand, asks Maahir to put sticks near the statue of Raavan, while she ask Bela to put some ghee on the same.
Yuvraj follows them and tells Maahir that in his presence no one can harm Bela. Then Bela asks Maahir to tell the truth. She slowly takes her Naagin form and Yuvraj notices the same.
He thinks that Bela will kill him now, but turns out that she didn't. Later, Sumitra asks Bela and Maahir to distribute sweets.
Yuvraj then asks Maahir to go on the other side and give away sweets. Bela is about to attack Maahir then, but notices a child running towards Maahir and hence, stops.
Yuvraj then loosens a rope because of which a burning part of the Raavan statue is about to fall on him. Bela notices this and somehow Maahir escapes the danger.
Back at home, Sumitra asks Andy (Chetan Hansraj) what is happening in the house. Andy answers saying that things have changed after Yuvraj has come.
He feels that Bela is cheating on Maahir with Yuvraj. Moments later, Sumitra finds divorce papers lying in her room with Mahir's name on it.
Meanwhile, Bela goes to meet Vikrant (Rajat Tokas) and wonders how things went wrong during the dahan and how Maahir escaped the danger.
Vikrant then reminds her how Maahir killed her mother, Naagranima, and that he is cheating on her and has vowed to destroy them.
Bela assures Vikrant that she will kill Maahir at any cost and she won't take anyone's help.
Bela then goes back to Maahir's room. On seeing this Andy is furious. He can't see Bela mistreating his son's feelings. He asks Sumitra to warn Yuvraj and Bela.
Bela, after entering Maahir's room, yells at him and says that he is a liar and that she is done with him. Maahir too shouts back at her saying that she has been blaming him unnecessarily.
On hearing them fight, Vikrant is thinking about the future and how things are going on as planned and how he soon will become the Naagraj.
While still fighting with Maahir, Beka suddenly whispers in his ear saying that she is doing all this so that Yuvraj doesn't sense that nothing is wrong between them.
She asks him to continue fighting.
Vikrant, unaware about Bela's strategy, is happy to hear that things are getting heated up between the two.
Maahir then takes Bela to the washroom and the two spend some quality time together. The two then think about something from the past.
So, Bela had informed Maahir that the one who has come as Yuvraj is fake. She says that he has come to harm her and mother. Bela then asks him to help her with a plan to reach her mother, where Bela will go alone to find her mother, while Maahir has to divert Yuvraj's (Vikrant) attention.
Bela then meets her mother and comes to know that vikrant and Vish (Anita Hassanandani) are planning something terrible and that Maahir is innocent.
Bela now knows that Vikrant is the one who had tried killing her mother.
