Raj (Bobby Deol), Yogi (Suniel Shetty) and Vikram (Irfaan Khan) are three fast friends. All three do business together. Young and beautiful girls are their weakness. Their wives Sanjana (Sonam Kapoor), Maya (Celina Jetly) and Shivani (Rimi Sen) are unaware of the fact what kind of people their husbands are! They don't know that their husbands are of loose character.

They go to some other places everyday instead of going to office. They go on enjoying but their bad times start when Yogi's wife Maya catches him enjoying with some other girl. Thereafter Maya notices one necklace in the neck of her friend Sanjana. She tells her that there was a scheme regarding the sale of that necklace which was another free necklace with that.

Maya tells Sanjana that another necklace Raj must have presented to one of his girlfriend. Sanjana does not have any proof against her husband hence she with the help of Maya takes the help of private detective Kishan Jasoos (Akshay Kumar) to find out the truth. Detective Kishan has already exposed many husbands and have mended their ways.

But this deal is not so easy. When Kishan takes the deal in his hands to catch Yogi and Raj red-handed, he finds it very difficult to be successful in his mission because Raj and Yogi are very clever and they don't give him any chance to collect any evidence against them.
