Amitabha Sengupta, a blind professor, divorced, humiliated, isolated, sets out for Trivandrum to take part in a seminar in a bid to rebuild his life from scratch. Let down by his escort, he is forced to travel alone on a train. As the train races through the shifting social and political landscape, Amitabha finds himself face to face with unexpected incidents and far more unexpected individuals. All these encounters make him oblivious of his sorrows and despair, and make him come out of the hibernation he had gone into. At the end of it all, he finds himself completely transformed. Not only is he altered by the situations but he also feels some of his interlocutors changing for better or for worse. It is a tale of a blind man's interaction with his surroundings-social, political and psychological not as a passive onlooker but as an active and enlightened individual.
