The movie begins with the birth of the protagonists, Shiva in Calcutta and Jennifer "Jenny" aka Selvi in Kuttralam in Tirunelveli district of Tamil Nadu respectively.

When both Shiva and Jenny complete their post-graduation and leave for their respective hometowns, they attempt to contact each other by phone to declare their love but fail.

They miss each other, but they write a letter declaring their love for each other and hand it over to their co-passengers on the train which they are respectively going to board.
