When Kavya Pratap Singh, a chirpy yet feisty girl from Ambala, makes a trip to Delhi for her marriage shopping, she meets a young, carefree Delhi lad, Humpty Sharma. Humpty's father owns a campus bookstore where Humpty and his two best friends, Shonty and Poplu, have grown up together and which remains their hangout spot even now. Kavya is unattainable for Humpty initially, which makes her even more endearing to him, but being a Delhi boy, he is not one to give up so easily. With some help from his two best friends, he finds out all about her, and through an interesting turn of events (including a ploy to save Kavya's friend Gurpreet's marriage), they start growing closer to each other. The more time they spend with each other, their love-hate banter grows, but their chemistry is apparent. They are both different, yet very similar as people. They are young, feisty and carefree, and it's the spurge of life which attracts them to each other. As per plan, once Kavya's trip ends, she heads back to Ambala, knowing very well that her father, the very strict yet loving Mr. Singh, would never accept her love for Humpty. Even though neither were looking for love, love happened; so, Humpty, flanked by his pals, decides to go get Kavya. That's the beginning of a journey for him that he wouldn't have imagined undertaking even in the wildest of his dreams. Humpty, against all odds, decides to convince Kavya's family to agree to his alliance with her. How he does this and if he succeeds in his mission forms the rest of the story. 夏马尔（瓦伦·达瓦 Varun Dhawan 饰）是一个成绩堪忧的差生，一次考试后，他担心自己的成绩不能及格，于是想了一个馊主意，那就是偷偷潜入改卷老师的家中对他进行威逼利诱。然而，在那里，夏马尔邂逅了老师的侄女卡维纳（阿莉雅·布哈特 Alia Bhatt 饰），美丽聪慧的卡维纳深深的撩动了夏马尔的心弦。 虽然卡维纳已经有了一位未婚夫，但是夏马尔还是无法放弃。卡维纳想要给自己置办一套名牌嫁衣，于是夏马尔和好友们绞尽脑汁帮助她实现愿望，在此过程中，夏马尔和卡维纳之间终于碰撞出了火花，可是他们的感情遭到了卡维纳父亲的强烈反对。
