After years of being apart, Satakshi and Madhu – who went to school together – reunite on a night of festivities during the ‘Durga Pujo’ in Kolkata. As the night progresses, we find out that both of them have feelings for each other that they aren’t able to express. Their secrets are preserved in a notebook entry by Madhu from her school days, and a postcard that Satakshi sends Madhu six years from this night.
