Three old retired men, Nabin, Nagen and Naren are the best of friends. Two of them are widowers and the other, childless. Everyday when they go for a morning walk, they discuss a bout a lot of things. One of them Nabin still believes that the elderly people still have a lot to contribute to the society and even to the themselves as they can keep themselves occupied and live life to the fullest as all is not lost. They decide to revive a tea stall which had shut down (owned by Mrinmoy, student of Nabin) and start things on a grand scale. After a month's operations it is seen that the stall is functioning well with a profit. There are a couple of hiccups along the way, but things are settled soon. Mrinmoy decides to help his cousin in his business and decides to go away, but is prevented from doing so by the three old men. Mrinmoy and Debalina (Nabin's tenant's daughter who he is very close to) decide to run a tutorial from Nabin's house.—Aditya Chakrabarty
