The story revolves around Kaushik (Prosenjit Chatterjee) and Kaberi (Konkona Sen Sharma), a happy couple until a car accident takes away Mita, Kaushik's mistress, and leaves Kaushik injured and grieving. Mita, the mother of a little boy and living with her husband, was Kaushik's colleague. This revelation leaves Kaberi shattered. Kaushik successfully moves on with life leaving Mita behind and tries his best to repair the severely wounded relationship with his wife. Another couple in the film, Brinda (Pallavi Chatterjee) and Bobby (Parambrata Chatterjee), are also engaged in an extramarital relation. While Bobby is a bachelor, Brinda, quite older than Bobby, is unhappily married. They and Kaberi do group theatre together. Brinda-Bobby comes to a crossroads when Brinda becomes pregnant and Bobby is not sure whether the child is his or her husband's. However, he does not turn back and stands by Brinda in sorting out her issues.

Kaberi often threatens divorce but ultimately is overpowered by the wife in her and cannot resist fulfilling her duties towards her husband at the time of crisis. On the other hand, Kaushik is also caught in his own predicament. He has to not only come to terms with the loss of a loved one but is faced with the daunting task of winning back his wife's trust.
