Omi Khurana's London dream has just ended. On the run from a dangerous UK gangster who he owes money to, Omi returns to his native village in Punjab, pretending to be a well-heeled London lawyer. Much has changed since Omi ran away from home a decade back after stealing money from his doting grandfather, Darji. The old man has since become senile and most importantly, forgotten the secret recipe of "Chicken Khurana" a dish that made the Khurana dhaba (restaurant) famous across Punjab. Omi's childhood sweetheart, Harman is soon to be married to his cousin, Jeet, though neither seems too happy about it. Adding to the quirkiness of the Khurana family is a free loader uncle, Titu, who once did a stint at a mental asylum. Will Omi be able to cover his deceit and lies for long, even as he tries to recover the lost recipe of Chicken Khurana - the family's only hope to reclaim their pride & wealth.

K.K. Khosla (Anupam Kher) is a middle class man living in New Delhi. He is a simple man with simple tastes. The plot starts with a scene where Khosla dreams about his death. The irony is that nobody cares about his death; instead his children & neighbours are more interested in their materialistic needs. One early morning in Delhi, Khosla wakes up and plans to go to the site where he has purchased a plot to build his house. He is accompanied by his wife, eldest son Bunty (Ranvir Shorey), second son Chironji Lal Khosla (Parvin Dabas), and his daughter. When they reach the spot they find that the site has been occupied by someone else and on further investigation find that it has been captured by a property usurping nexus headed by a man named Kishan Khurana (Boman Irani). Khurana demands Rs. 15 lakhs to vacate the plot, which Khosla refuses to give. Bunty gathers few local strongmen and forcefully destroys the walls and re-occupies the plot...
