After being acquitted for Periyavar's son-in-law's murder, Nandha returns home. His paranoid mother, who still believes that her son still has murder instincts, waits at home to feed a meal, which she has poisoned herself. He finds out that the food is poisoned when he eats it, but continues to do so with a satisfaction that he is being fed by his mother. Nandha dies in his mother's lap and when his sister and Kalyani come out to see what has happened, they realise that both mother and son are dead.
