The story of Kitne Door Kitne Paas starts in the US where Fardeen Khan and Amrita Arora live with their families. Both come from traditional families and their parents choose their respective spouses in India. Just before they come to India to marry, they accidentally meet at a mall where they end up having a small argument. They end up traveling together on the same flight from US to New Delhi from where they have to head to Gujarat, where he is supposed to get married to Sonali Kulkarni, while Amrita is all set to take tie the knot with Ayub Khan. But on reaching Delhi, they lose their money and are in a tight spot. They don't know how to get to their destination and finally Fardeen decides that they board a bus for Gujarat together. But as luck has it, the bus they board is reserved for married couples exclusively (very strange) so they both have no choice but to pretend to be a married couple.
