Aditya (Shahid Kapoor), a defeated industrialist, is even more broken as the girl he loves is getting married. Unable to muster up the courage to return home, he drifts out of the gathering and aimlessly boards a train, bounding away into the night.

As destiny would have it, on the train he meets Geet (Kareena Kapoor) - a beautiful but annoyingly talkative girl who is leaving Mumbai to go her hometown - Bhatinda (Punjab). Later, she has plans of eloping with her boyfriend.

Geet irritates Aditya to the point of getting him to leave the train. As she tries to get him back on the train, she ends up missing it and the two find themselves stranded on a desolate station with no luggage or money.
