Thanappa is more than just a postman to the Ramanujam family. He shares their good news and also wallows in their sorrow as well. Thanappa is instrumental in bringing about their daughter’s engagement — the one whose birth he had brought news of almost seventeen years ago. Thanappa finds himself in a tricky situation, when a day before the happy occasion of her marriage, a letter arrives bearing news of Ramanujam’s elder brother’s illness and a telegram follows with the news about his passing away. Thanappa is in a dilemma whether he should risk by telling the family on this happy day or postpone the delivery and risk getting sacked for his efforts, thus bringing to light the problems of arranged marriages in a middle class family.
