The film begins when Suhaan receives a notice saying his ex-wife Piya, who has settled in New York, wants a divorce settlement of 5  million rupees, because of his failure to make his alimony payments due to his poor financial condition. Suhaan appeals to his uncle Bonney Kapoor (Anupam Kher), a midget lawyer, for help. While they are trying to figure out a solution, Agastya Rao (Akshay Kumar) lands at their doorstep searching for Piya. He reveals to them that he fell in love with Piya during his college days but could not express his love to her because she was in love with someone else, unaware that the person he lost her to was Suhaan. Piya had ignored Agastya then, a nerd, a nobody, and even broke his heart by blowing him off to be with Suhaan at a concert that Agastya had taken her to. A heartbroken Agastya left the college as a result and eventually wound up in Houston working for NASA.
