Snehamoy, a teacher in a school in the interiors of South 24 Parganas leads a lonely life with his Mashi. The only thing that keeps him going is his exchange of letters with Miyage, his pen friend from Japan. They have never met, yet they communicate to each other in a foreign language-English, a language in which neither of them is good at conversing. When Sandhya, his Mashi’s god-daughter is brought to him for her to choose her as his bride, a letter comes to him where Miyage offers herself to him as his bride. He accepts the offer. Fifteen years pass, still they have not met each other. Sandhya, now a widow comes to stay with her son Paltu. Though their paths never cross Sandhya takes up the reins of the household very well. Paltu too becomes very attached to Snehamoy. When Miyage falls very sick, Snehamoy tries to seek the help of every kind of doctor possible trying every possible treatment and even sends some medicines and herbs to Miyage who has got cancer. One day when Snehamoy goes to Kolkata to see an oncologist, there is a fierce storm. He gets caught in the storm and gets pneumonia. He falls severely sick and Sandhya tries to nurse him back to health and the doctor is also consulted, but nothing can be done. Snehamoy passes away without reading Miyage’s letter which had arrived after the storm saying she was a little better and on her way to India. She arrives in Gosaba only to find that Snehamoy has passed away.
