His daughter, besides doing college education, is also attending a dance class. She is in love with the dance master Unni, whose mother is a well known dancer. However Unni's father's details are not revealed by his mother as he had died before their marriage and his birth. On knowing that her daughter is in love with dance master, Bharathi reaches the dance school and shouts at them, calling him a Bastard. She also suggests her club members to refrain from sending their children for the dance class. Ramachandran was much disappointed about this incident as he too had an illegitimate son. Ramachandran's son Sreekuttan and his mother Priya are living in another house at a place where one of his project is in progress. He has a happy life there too, enjoying all freedom. He visits them often and only his best friend knows about this relationship. Though he was willing to marry Priya, she told that it is not required as she is much confident to live with his son. His best friend also suggests that the marriage will turn void as it does not have the consent of his wife. However Ramachandran plans to write his house in the village in Sreekuttan's name. Things go worst as Ramachandran suffers a heart attack and is admitted in the ICU section of hospital. He becomes speechless, and informs his best friend that he wants to see Priya.

However Bharathi sees both of them, just before leaving the ICU. Ramachandran passes away that night. His brother in law was just about to cremate the body when Sreekuttan shouts for his father and runs towards the body. Ramachandran's friend reveals that it is Ramu's kid and, as per rituals, if there is a son for the deceased, it's he who should perform the last ceremony for his father. And so, Sreekuttan performs the last rituals and lights the body for cremation. Bharathi's hatred toward Priya increases.
