The story revolves around the lives of Gopal (Ajay Devgan), Lucky (Tusshar Kapoor), Mahadev (Arshad Warsi) and Laxmi (Sharman Joshi) - 4 guys bound together by their child like notoriety, aimlessness and petty business of conning people for fun and money.

Gopal is the wisest and the wickedest of them all and the motto of his life is to eat, drink and be merry (Kal Kya Hoga Kisko Pata…) Mahadev and Lucky are also of the opinion that only idiots work and wise men use them in more ways than one to make their life comfortable. Among these 4, there is Laxmi, who is a sincere and god-fearing guy and a bright student.

At one point, due to their notorious acts, the dean of their college throws them out of the hostel and they have nowhere to go. Gopal the wittiest and the biggest bully of them all, tells them about a bungalow which is inhabited by an old blind couple, whose son daughter-in-law and grandson are in America.

Gopal plans to enter the bungalow pretending to be Prashant (the blind couple's grandson) He also asks the rest of them to move in with him - the only condition however is that everyone, except for Gopal would always remain silent. This bizarre sequence leads to much confusion throughout the film creating lots of comedy.
