The story is undeniably stimulated from the life and feats of the trade magnate Dhirubhai Ambani. And Mani exploits this summary to weave out a tale of a man who is fittingly into manufacturing and fabricating polyester fibre and soaring the height of success.

Gurunath (Abhishek Bachchan) immigrates to Istanbul where he finds the true inspiration of his life. Although he delivers his job with full candor and enthusiasm, he is plagued by the idea of making his work benefit him rather than coming to the service of others especially the whites. So he packs his belongings and returns back to his grimy rural village in Gujarat only to find his true calling. But the task is not easy for him, as he has to encounter many barricades on his way- family displeasure, fiscal aridness and little support from every one.  

Guru spots Sujatha (Aishwarya Rai) and right away takes a liking for her and resolves to get hitched. But the real motive behind tying the knot above anything else is the dowry money that he would get his hands on, which he will be able to invest in his business enterprise. Gurunath is ambition personified and will stop at nothing to make it real big. Guru’s biggest strength is that he has great philosophical insight into the mood and many of human minds. By luck or by chance he enters into a friendship with eccentric press mogul Mangaldas (Mithun Chakraborthy). This bond opens the big door of trade for Guru. Guru also gets into a very enticing and enigmatic bond with Mangaldas’ multiple- sclerosis ridden daughter played by Vidya Balan.

The roads aren’t very smooth for him initially and he has to slog hard to establish a niche for himself. But he finally manages to win over the hurdles with his rationality and sincerity. Guru destabilizes the system while moving ahead and this annoys Mangaldas who inspite of being a hard nut likes to adhere to the rules. What follows next is literally a cat and mouse chase between Guru and Mangaldas who hooks his best man Shyam (Madhavan) to scour out details of his off hand dealings. This turns out to be clash of the Titans. Guru who likes to go by his own set of rules is popularly well acclaimed by the public and this aids him to take a big leap out of the pool of problems.
