When he was entering into his 100th year, instead of feeling happy, Sundar felt quite irritated and sorrowful. He requested his granddaughter Rupa not to make any arrangements for the celebration of his birthday. Without bothering with his protestations, Rupa made the arrangements for the celebration of his birthday and made it a success. Sundar felt so much happy when his friend Somaraj a 96 years old man came to his home to stay with him for few days. But the way he was treated by his sons and daughter in laws was always a sorrowful thing not only to Somaraj but to Sundar also. When Sundar could manage to join Somaraj in Nischal Old-age Home which was indeed a happy home for the old people to stay, both Sundar and Somaraj felt so much happier.

'Nischal' the owner and founder of Nishcal Old-age Home, even he was just forty six years aged guy, quite knowledgeable and understandable about old people and their problems. There are many old people staying in his old age home and all of them were quite happy to stay there because of the facilities that Nischal provided for them in that old age home. They equally enjoy the lectures that Nischal would give in the evenings in that old age home.

'Dusk' is the story of old people, about their thinking, about their psychology, about their problems and in fact it is heart beat of old people.
