The Kapoors have always wanted their only son Rahul (Imran Khan) to be a go-getter and have groomed him appropriately since childhood. But when Rahul is sacked from his new job in Las Vegas around Christmas, he is compelled to visit a psychotherapist to vent his insecurities. There he meets Riana Braganza, a hairstylist who has recently broken up with her boyfriend. Riana and Rahul bond over drinks and paint the town red on Christmas Eve. The next morning, they discover that during their drunken spree the night before, they got married. They decide to annul the marriage, but when Riana can't pay her rent and her landlord evicts her, she lands at Rahul's place. A friendship develops between them over the course of the next few days and a trip to India.
