Rajan Mathur (Anil Kapoor) is a Professor in Urdu literature in Dr. Zakir Hussain's College. He resides in Chandni Chowk with his activist wife, Roma Mathur (Shefali Shah). Professor Mathur comes across a young boy called Numair Qazi (Anurag Sinha) who introduces himself as a victim of communal riots in Gujarat. But in actual fact, he is a suicide bomber commissioned by a Muslim fundamentalist group to detonate a bomb near Red Fort on 15th August. This premise forms the story that unfolds in this black and white film which moves forward with the colors of love, hate and redemption.
