Gopal (Ajay Devgn), who lives with his soap-drama-watching-wife Ekta (Kareena Kapoor), sister Esha (Amrita Arora) and a mute brother-in-law Lucky (Tusshar Kapoor), gets stuck in a yacht one night after he saves an attractive young woman Meera (Celina Jaitley) from some dreaded goons, while on his way back home from the office. Due to the circumstances, both of them stay back on the yacht.
When he arrives home the next day, his over suspicious wife Ekta, suspects him of flirting around with his female employees and having an affair with unknown woman. Knowing how difficult it is to convince her the incident that actually took place the previous night, he invents a story about spending the night with a fictitious friend named Anthony Gonsalves. Ekta becomes suspicious and does not believe his story as she knows that he never had a friend by that name, and hence, she decides to write to Anthony to come and visit her for satisfaction and to confirm Gopal was telling the truth.
