The depth of brotherhood shared between Jayakrishnan and Harikrishnan is ruined when Meghna Reddy enters the Palakkal House as Hari's wife.
When Jayan went to Singapore for higher studies, Nadesan killed Aswathy's father in front of her own eyes and then kidnapped and tortured her.
Believing that Jayan betrayed her, Aswathy has returned as Meghna to take revenge, with the help of her guardian Swamiji.
The story moves forward as Meghna proceeds with her revenge and, one by one, the members of Palakkal family realize the truth.
The story ends with Meghna committing suicide after killing Swamiji, while Jayan, Sumithra and Malu live happily ever after.
