Two strangers, a girl from Mumbai and a boy from Pune meet accidentally. As she is new in Pune the boy helps her to find the address she is looking for. In the time they spend together she reveals that she came to Pune to meet a boy for marriage but she is going to reject him as she does not believe in 'arranged marriage'.
She tries to call the boy she is supposed to marry, but her mobile phone is low on battery. She then tries to call from the helping boy's phone but she finds the number is on another call. Unable to reach him, they start talking, and start to like each other.
At the end of the day, he drops her in the Railway Station and when she asks the boy his name, he says 'Pune' and she says her name is 'Mumbai'. She accidently takes his phone with her. While she is in the train, she gets a call on that number and the boy she was supposed to meet asks her to come out of the train as he's come to receive her.
The twist is in the ending of the movie when she steps out of the train to meet him.
