Dum Laga Ke Haisha

In 1995,^[13] Prem Prakash Tiwari is a young owner of a video cassette shop in the local market of Haridwar, who subscribes to a nationalist organisation. One of the key values of the organisation is abstinence, although senior members are married and there are no restrictions on the marriage of junior members. However, it is expected that their members should not indulge in their married life at the expense of service to the nation. His father is keen on getting him married to an educated overweight girl Sandhya. In spite of not liking her, the school drop out Prem agrees to marry her. In addition, as Sandhya is trying to be a school teacher, his family asks him to think of this alliance for financial help too. Eventually, in an elaborate community-wedding ceremony, Prem and Sandhya get married.

Prem visibly shows his disinterest in the marriage and does not consummate the marriage on the wedding night. At home, Sandhya tries to get Prem attracted to her. But he is too embarrassed to even walk with her on the street. Prem and Sandhya's relationship remains strained although they share a kiss and have sex on their second night together. The branch manager advises him that since he could not uphold his oath of abstinence he should rather focus on his married life. Over time, Sandhya's frustration shows; when Prem's aunt brings up a petty topic, the two have a heated exchange of words and she tells them how he does not treat her well.

Amidst all this a close friend of Prem, Nirmal gets married. Prem and Sandhya go for the ceremony where due to his excessive drinking and jealousy over Nirmal's pretty wife, he tells everyone that sleeping with Sandhya feels like hell. Sandhya hears this and slaps him in front of his friends and he slaps her back. The following morning, Sandhya reflects on what she's been through, feels she has had enough and decides to leave Prem. Meanwhile, Prem decides to channel his energy into studying and to take his English paper again; he enrolls for the examination. His friends give up on him; after a verbal squabble, they throw him out of the group. He studies sincerely for the exam, but at the time of his exam, he is overwhelmed by the emotional turmoil and is not able to write a word. Ultimately he plainly writes an emotional message to the person checking his paper that if at all he feels any pity for his state he should not award him with a zero or else his family would be reduced to zero (indicating his suicide attempt).

Soon, Nirmal's father opens a shop selling music CDs in the same market, clearly affecting Prem's family business. Prem's family talks to Nirmal's family and the discussion ends with Nirmal challenging him to participate and win the "Dum Lagao" contest, which entails him carrying his wife on his shoulders and running an obstacle course. Meanwhile, Sandhya and Prem reach the court to file for divorce. Prem's father pleads the judge that divorce should not happen on petty issues and his family is more than happy to take her home, Sandhya's parents too feel the same and support him. The court decides that the two must spend six months with each other and try to salvage their marriage. Both decide to live together just as a formality, but they soon begin to get on, as they both start understanding each other. Meanwhile, Sandhya is coerced into the contest. They start getting close with each passing day, but according to Prem, they lack co-ordination and are a total mismatch.

One day as Prem returns home, he is disgusted to see that his family members are pretending Sandhya's terrible culinary skills. He finally snaps and expresses his anguish over this pretense, and attempts suicide. A police constable arrives at their home, owing to a complaint regarding the emotional letter (attempt to suicide) he had written in his English exam. Sandhya is moved by this, and they have a deep conversation with each other. Sandhya gets a teaching job in Meerut, which she gladly accepts since she feels that there is no one who cares about her anymore. When she tells Prem about it, he cannot come to terms with losing her and realises that he is in love with her.

On the day of competition, Prem's aunt successfully convinces him to participate in the competition and the couple takes a last chance to save their marriage. Surprisingly, Prem shoulders the weight of his wife and surges past all other contestants. In the last lap, Sandhya confesses to Prem that she does not want to go to Meerut and wants Prem to let her stay. Prem knows winning this competition is the only way to do this and pushes himself further to eventually win the race.

Prem does not let Sandhya get off his back even after the race is over. He takes her back all the way to his house where they seal their love with a kiss.

Dum Laga Ke Haisha was the first Yash Raj Films production to not be produced by Aditya Chopra; he instead served as a presenter and onboarded director Maneesh Sharma, who had helmed three of his previous productions, namely Band Baaja Baaraat (2010), Ladies vs Ricky Bahl (2011) and Shuddh Desi Romance (2013) to produce the project. Writer and director Sharat Katariya had sent the script, which was written in 2007, almost seven years before release,^[15] to Yash Raj Films; Chopra sought to launch Sharma as a producer for new age avant-garde projects for the company, and they selected Katariya's script for the endeavour.
