Kavya Pratap Singh, a beautiful, educated and stylish Punjabi girl from Ambala who is set to be engaged to an NRI American doctor, decides to go to Delhi to buy an expensive designer bridal dress for her wedding, after her father, Kamaljeet, refuses to get her the pricey dress. While staying at her maternal uncle's house, she comes across one of his students, Rakesh "Humpty" Kumar Sharma, a young and flirtatious Punjabi boy in Delhi, whose father, Vinod Kumar Sharma, runs a stationery shop. Humpty, with the help of his friends, Shonty and Poplu, chases Kavya, but she's not interested. He, however, manages to befriend her. Kavya confides in Humpty, that her friend in Delhi, Gurpreet Sodhi, was blackmailed by her ex-boyfriend, who had secretly filmed a sex sequence of the two, Humpty stumbles upon an idea for victimizing Gurpreet's ex-boyfriend that would also avenge Gurpreet, and also gather the money for the wedding dress for Kavya. They manage to get some money but Kavya isn't happy about the way that money is obtained. However, these ensuing adventures make Kavya fall for Humpty, and the night before she is to leave for Ambala, they Have Sex and end up sleeping together. When Humpty asks her if she loves him, she says she won't go against Kamaljeet's wishes. In order to help Humpty get the money for Kavya's dress, Vinod, Poplu and Shonty chip in their savings. Kavya reluctantly accepts the money and leaves Delhi, Kavya is a changed person when she arrives home. She tells her family that she has decided not to buy that expensive dress. In the meantime, she gifts a fancy car to Humpty using that money, as she had known from him about Vinod's dream for a car. Overwhelmed, Humpty and his friends go to Ambala, where he tries to win over Kavya. Kamaljeet believes firmly in arranged marriages against love marriages, as his elder daughter, Swati, married against his wishes and the marriage turned out to be a disaster ending in divorce. Kamaljeet instantly disapproves of Humpty, and gets the three friends beaten up. Upon repeated persuasion, he gives Humpty a chance to find at least one reason why Kavya shouldn't marry Angad. He sets him a five-day deadline to give him the reason. Humpty and his friends try their best to find flaws in Angad but fail to do so, At the end of the deadline and on her wedding day, Kavya runs away from home and calls Humpty to join her on a train to leave town, but which he refuses and convinces Kavya to get off the train. Meanwhile, Kamaljeet and the rest of the family reach the train station, where Kavya and Humpty are embracing each other. Kamaljeet, wrongly assuming the pair was eloping, is enraged and hits Humpty, who gives a powerful and touching explanation saying that he may not be as rich, successful or good-looking as Angad, but he loves Kavya from the core of his heart. He leaves Ambala and heads back to Delhi after that incident. When Kavya is dressed up as a bride, Kamaljeet asks her if she still fancies that expensive wedding dress. She replies she's not fit for expensive classy dress, but is suitable for local dresses. As it dawns on Kamaljeet that her relationship would be fuller with Humpty and not Angad, he brings everyone to Delhi where he approaches Humpty and gives his consent to marry his daughter.
