Raj Malhotra (Shahid Kapoor) is an architect who hasn't made a great deal to prove his brilliance, which he thinks he has because he had been a great student in college and won many prizes during college time. He seems to be very unlucky for many times and his bad luck is always stopping him from gaining success. His college student Hiten Patel (Vishal Malhotra) is now his colleague.
One day he is supposed to have a meeting with a big company boss, whom he expect to sign a big deal with. His bad luck comes to him again: his alarm clock stops ticking one minute before it is supposed to alarm, making him having slept for 30 excessive minutes; the water supply in his house is interrupted when he is taking a morning bath after waking up late; his car can't start after he finally finishes his shower; he decides to take a taxi, but finds no money in his wallet; when he is withdrawing money from an ATM, the machine is not accepting his card; when he is carrying on, his car nearly hits Priya's (Vidya Balan), which however makes him miss a small accident that can have happened to him; and finally, he gets rejected by the boss.
In another try, Raj and Hiten meets Gill Patra's CEO Harry Gill (Om Puri) and they expect to sign a big deal with him. To their surprise, Mr. Gill has just had a meeting Dev Kataria (Karanvir Bohra), whose proposal interests him a lot and whom happens to be colleague of Raj and Hiten. Mr. Gill is therefore not in mood of having meeting with Raj and Hiten, and excuses them to come at another day.
Again, when Raj is withdrawing money from an ATM, the machine is not accepting his card, where coincidentally Priya is waiting in queue. They meet and have a quarrel again, during which Priya throws Raj's name card away and it accidentally falls to the hand a business man who is eager for an architect. Raj gets the deal. The project is not big, and the contractee invites Raj and Hiten to the celebrating party of the project completion. After learning Mr. Gill will also attend the party, they agree.
However, Priya happens to meets Raj again, right in the party, during with Mr. Gill is playing billiards with his friend Sinha. With unintended help of Priya, Raj helps Mr.s Gill with a critical shot, which impresses Mr. Gill and the latter agrees to meet him again to discuss with his proposal.
