Gayathri spends her time scolding her husband Raghu for his sudden strange silence.
A few years ago, in Kanyakumari, the blind Raghu found Dhanasekhar (Yugendran) and his sister Bharathi (Anumol), who had just lost their parents.
One day, Dhanasekhar had a severe accident and died but not before telling Raghu that he donated his eyes to him.
Persuaded by the pleas of Joseph Aruldoss and Bharathi, Raghu reluctantly accepted for the eye transplant.
However, after the operation, Raghu mysteriously vanished, leaving his astounded lover Bharathi in tears.
Back to the present, Gayathri finds out that Raghu was a blind person who can die at any moment due to the injury that he sustained in the past.
Raghu explains to him that after the operation, he had a part of Dhanasekhar in him and could not marry Bharathi, who also became his sister in the process.
