Plot

Enroute to her destination via plane, a busy executive gets stranded with a middle-classed fast-talking male.

While on her way to Mumbai airport to board a plane to Delhi, a busy business executive, who employs over 600 employees, gets stuck in a traffic jam, and misses her flight. She blames her predicament on an auto-rickshaw passenger, Manu Gupta, and is appalled when the latter is her co-passenger on a budget-airline. The flight is diverted to Jaipur and with no flights available for several hours, she ends up sharing a rental car with Manu - but matters get even worse when the car breaks down, and both end up spending the night at a cockroach-ridden restaurant. At daybreak, she ends up having no luggage, no car, and forced to ride a camel-cart with Manu, who she cannot stand anymore. But things get even worse when she will find her money has been stolen; the duo will be arrested for traveling on a train without tickets; and end up hitching a ride from men who have just broken out of jail!!—rAjOo (gunwanti@hotmail.com)

A high class executive gets thrown off-schedule when she misses her flight. She tries to make her own way but trouble keeps finding her and so does a middle class Delhi local who soon becomes her co-passenger and in course changes the way she sees life.—Vaibhav Bagaria

Mihika Mukherjee (Lara Dutta), a successful investment banker living in Mumbai, misses her flight to Delhi and needs to get there any way possible to meet her husband, Lt. Col. Vikram Rathore (Akshay Kumar). She meets Manu Gupta (Vinay Pathak) at the airport. Mihika hates Manu at the outset. She is suave and sophisticated, while Manu is agricultural. Mihika is desperate to get to Delhi as its Friday and she is scheduled to leave for LA on Sunday & wants to spend some time with Vikram. Vikram is upset as it is Mihika's birthday on Sunday, and he wanted to throw her a party that night. But Mihika says that she is not interested in doing anything anyways.

Mihika misses her flight as she leaves late from the office and then encounters a large traffic jam and a rally which blocks the regular roads. By the time her driver takes a diversion and gets her to the airport, she finds that she has missed her flight. She gets the next flight to Delhi in a Low-cost carrier, which Manu has boarded as well. Due to a technical issue at Delhi airport, the flight is diverted to Jaipur. Mihika is so absent minded that she realizes that she in in Jaipur after she exits the airport.

Mihika hires a cab at Jaipur, but she yells at the driver ShivRattan (Narottam Bain) when he gets sleepy at the wheel. The driver asks Mihika to get a different cab & stops the car, that's when Manu comes to her rescue & threatens the driver to act straight. He boards the cab to make sure he does.

The driver is still sleepy, so Manu takes over the wheel. Mihika goes to sleep & wakes up shortly afterwards to realize that they are going back towards Mumbai! Manu has lost the way & to top it off, the car breaks down. If that was not enough, Mihika's mobile phone battery goes dead, and she cannot contact Vikram either. Manu lends his phone to Mihika to inform Vikram. Manu says that it will take 2 hours for a mechanic to come and only then the car can be fixed.

The duo abandons the car & their luggage with the cab driver & board a truck with driver Dharampal (Dadhi R Pandey) to the nearest rural eatery to have food and wait for the cab to be fixed. After having dinner Manu goes back to see if the car is fixed but comes back with his bags informing Mihika that the car has been taken to garage. He forgot to get her bag which was inside the boot of the cab. Mihika gets massively angry at Manu & lets him know as such.

They have to spend the night at the rural eatery & next morning Mihika is amazed at the beautiful Rajasthan in sunrise. She apologizes to Manu. They hitch-hike a camel buggy & then a tempo to reach the nearest railway station. There Mihika proceeds to buy a first AC ticket, when she realizes that her bag is torn & all her money has fell through. Manu is already on the train when he realizes that Mihika couldn't get a ticket. He pulls the chain to get the train to stop & helps Mihika into the general compartment. Although Manu has a ticket, but Mihika is travelling WT. So, when the TT KC Pant (Brijendra Kala) comes calling, Manu bribes the TT, but also insults him behind his back which the TT hears & throws them both off the train & hands them to local police.

The inspector demands a bribe, but the police station is attacked by a gang of local thieves who want to free their colleagues. Manu asks for a lift from them! The gang leader wants revenge on the snitch who got his members arrested. During the ensuing chase, Mihikaa's clothes are torn from the sleeve. Finally, after it turns out that they were chasing the wrong person, Manu & Mihika are dropped in the middle of nowhere.

They trek to the nearest town Jhunjunu & check into a seedy local hotel from where Mihika calls Vikram & asks him to come and get her. That night there is a gents entertainment program in the hotel basement which has attracted the worst crowd of the town into the hotel. Manu attends the function & pukes the beetle leaf residue on a local politician. The politician, Bhaiyaji (Teddy Maurya) thinks that his rival Pandeji (Mukesh Bhatt) has done this & a huge riot breaks out that results in a curfew of Jhunjunu. Now Vikram can't get in to get Mihika.

Vikram gets to Jhunjunu & refused entry, but he flashes his military credential & gets in. He gets Mihika from the hotel & also picks up Manu & starts for Delhi. Vikram drops off Manu at Chandni Chowk. Mihika's attitude towards life undergoes a change and she learns to take it a bit easy. On the way home she decides she wants to invite Manu for her Birthday party & calls him but realizes he has given her an invalid number. Mihika goes back to Chandni Chowk & traces Manu's home. There she finds that Manu's wife Vibha is comatose for the last 2 years from brain fever. She is amazed at Manu's attitude towards life that made him not say even a single word about his suffering to anyone. Manu believes in spreading only joy.
