Billu is a story of a simple ordinary man who led an extra ordinary life. Bilas Rao Pardesi (Irrfan Khan) was living in his village with his wife Bindiya (Lara Dutta) and two great kids. Life was bitter sweet... we can say more sweet than bitter.
One day a superstar Sahir Khan (Shah Rukh Khan) came into their lives and everything changed. Life changed, people changed, friends changed, the village changed but one man did not... Billu.
Will this ordinary man redefine the words ordinary? Will the words see the greatness behind his small existence? And most of all, Will life ever be the same for Billu again?
