The film is divided into three parts from the view of characters:
Abhay Deol), the son of a rich businessman, is an insecure narcissist. He and Paro (
Mahi Gill) are childhood sweethearts. Instead of acknowledging her affection and care, Dev nudges Paro over frivolous things. He is sent to
London for higher studies when his father senses how spoilt his son is. While separated by distance, Paro and Dev's youthful love only blossoms more. After finishing his studies, Dev returns to Chandigarh and meets Paro. Their endeavor to make love makes for some dark comic moments. When Dev hears rumours about Paro, he immediately believes them and ditches her. The seeds of suspicion are sown here, which the couple are never able to weed out. What makes them fall apart is mutual suspicion and an essentially male vision of how a woman should conduct herself sexually. Paro turns her back on him when she hears him insult her and agrees to marry a man of her parents' choice. On her wedding day, Dev learns that the rumors were false but his ego doesn't let him accept his mistake, and he lets Paro marry someone else.
Kalki Koechlin) is a Delhi student of half-European descent. A date with her much older boyfriend lands Leni in an
MMS scandal. Her father commits suicide out of shame. She is disowned by her family. Refusing to live a life of shame and ridicule, she returns to Delhi where she works as a
prostitute at night, while continuing with her studies during the day. She adopts the name 'Chanda' for her profession. Her 'foreign' looks mean her services are reserved for the highest-paying customers and she finds some dignity and independence in the new way of living. One night a customer is brought to her room in half-conscious state — it turns out to be Dev.
Dev, tormented by Paro’s wedding, has been seeking refuge in alcohol and drugs. He finds some solace with Chanda but is unable to forget Paro. Once after he calls Paro's husband in the middle of the night, she visits him at the cheap lodge where he is staying. She shows her love by taking care of him but spurns his attempts at physical intimacy. The meeting ends on a bitter note, and Paro returns to her married life while Dev resolves to go back to Chanda; confronted by the reality of her profession, he abandons her, too. It is only months later, after hitting an all-time low in an aimless life, that he gets a wake-up call and decides to put his act together. He seeks Chanda once again and, with her help, sets out to start life afresh.
