No Entry is the story of three men. Kishen (Anil Kapoor) - 'the married man' Sunny (Fardeen Khan) - 'the Bachelor' Prem (Salman Khan) - 'the married bachelor'. Ironically, while the faithful Kishen has a very suspicious Kaajal (Lara Dutta) as his wife, play boy Prem has a trusting wife Pooja (Esha Deol). And then there is Sunny's-to-be wife Sanjana (Celina Jaitley) who is a bit of both. Trouble brews when Prem decides to make Kishen taste the forbidden fruit that he loves so much. This forbidden fruit assumes the form of sultry siren Bobby (Bipasha Basu), who walks through the board right into the lives of them all, leading to chaos, craziness, commotion and crisis.
