The belief among the family is that one male from each generation will go mad as a person from their previous generation had sinned by throwing the idol of the family goddess in a well. He was cursed by the goddess and became a lunatic. This curse is supposed to pass down through generations. Balan's uncle finally dies and the talk of the village became - "Who would be next - Balan or Gopi ?" One night changes it all when Balan has a terrible nightmare. The whole house is woken up in the middle of the night. The elder members of the family suspect that Balan is turning mad. The news somehow gets out.

He applies for an extended leave and transfers from service. Even some members of his family suspect that he has gone mad. The situation affects Balan and turns him confused. Gopi, progressive and educated, consult Balan with a medically qualified physician. The physician declares him sane. But the village doesn't agree. In the meantime, Balan's wife is forced to leave the house with their children. The family fixes the marriage of his younger sister while hiding the fact she has a "challenged" elder brother. Eventually, Balan is admitted to an asylum and undergoes treatment. He is released after a few days - both mentally and physically broken - and confines to the darkroom his uncle once lived in. Society hounds him and beats him into mental subjugation. Balan's mother eventually poisons him and kills him on the day of the ritual for forgiveness from the goddess - to free him from the world. The same hands which had fed him his first morsel of rice became the ones that fed him his last meal. She too kills herself, as she couldn't forgive herself for this heinous act.
