Ashish Kapoor (Akshaye Khanna) is a creative soul termed as a genius by his advertising agency. To make things complicated, he is a raving hypochondriac whose paranoid behaviour and insecurities about his love life with girlfriend Rani (Ayesha Takia) adds to his woes. Although Ashish loves Rani immensely, one day he decides to break up his engagement to give Rani a better life. After numerous failed attempts, he manages the breakup by pretending to be involved with the sexy, international model Sania (Mallika Sherawat). Ashish's relief is short-lived as he realizes that the sexy Sania is now deeply in love with him and to top it all, has an international mafia don (Suniel Shetty) as a brother who would kill him if he doesn't marry her. Ashish has no escape no support no hope he wants to return to Rani, but now she is not interested in him. What follows is a very hilarious, rib-tickling comedy of errors and more errors.
