On 1 November 1984, a day after Prime Minister Indira Gandhi's assassination, a nineteen-year-old student, Raj, travels back from a class trip with his mentor, Professor Singh. As the group disembark at Delhi station a mob surrounds the professor, throws a tyre over him, douses him in petrol and sets him alight. Years later, after moving to the United States, Raj finds himself compelled to return to India to find his professor's widow, the beautiful and enigmatic Nelly. As the two walk through the misty mountains of Shimla, painful memories emerge, and Raj realises he must face the truth about his father's role in the genocidal pogrom. But, as they soon discover, the path leads inexorably back to that day at the train station.
