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.

After the passing away of his wife, Pooja, Delhi-based Vikram Madan, enrolls his daughter, Priya, in a boarding school in Amritsar, and re-locates to work as a Mechanic at Chandigarh Airport. His daughter informs him that she is on her way to Amritsar on a hostel-trip on Indian Airlines Flight IC147. Shortly thereafter, Vikram will be informed that the flight has been hijacked to Dubai by Islamic terrorists, who want the Indian government to release one of their comrades, Rashid Omar, or else they will start killing the passengers and crew one by one at half-hour intervals.
