The story is about Mudit Sharma (Ayushmann Khurrana), a Delhi boy with a marketing job, and Sugandha Joshi (Bhumi Pednekar), a Gurgaon girl whom Mudit falls in love with. Shy by nature, Mudit tries all possible ways to talk to Sugandha but fails. Finally, he decides to send her an online marriage proposal. When the two finally meet, they feel the sparks and decide to take it to the next level. Sugandha takes her time deciding whether to accept the proposal and later calls it her first major decision for her own life. A formal marriage proposal is exchanged between their families. When Sugandha's parents are out of town, Mudit and Sugandha try getting intimate and when they finally reach the bed, a visibly uncomfortable Mudit declares that he needs to use the washroom. But when he returns, he gets dressed and makes for the main door. When a concerned Sugandha asks him about this sudden change of plans, he simply hints at his problem with the help of a biscuit, getting Sugandha to realize that he is facing a bout of erectile dysfunction. Mudit and Sugandha try different ways to solve the problem but fail, and when Mudit comes face to face with the reality of his impending marriage, he decides to cancel it. They argue. Now deeply in love, Sugandha refuses to cancel the wedding and says she will expect him and his baaraat (wedding procession) at the venue. Eventually, accompanied by a posse of assorted relatives, Mudit leaves for Haridwar where the marriage is scheduled to take place. During the journey, Mudit constantly receives calls from someone stating that he is a well-wisher and knows about his problem. When he reaches Haridwar and the calls continue, Sugandha takes the call and showers abuses on the unknown person before suddenly realizing that the well-wisher is none other than Sugandha's father. Mudit's future father-in-law takes him to consult with a veterinarian who suggests that the cause is stress. A day prior to the wedding, Sugandha and Mudit try getting intimate one more time, egged on by relatives from both sides of the family. When they exit the room sometime later, they find every family member waiting expectantly about Mudit having done 'it'. Mudit says that he managed to perform but Sugandha disagrees. The families are now deeply worried. As the hour of the wedding approaches and troubles and disagreements pile on, Mudit stands up for Sugandha and their relationship against family/societal expectations. He even risks his life to stand up for the love of his life, Sugandha. He rejects toxic masculinity and they together define their marriage as a team of equal players. The wedding takes place. In the closing narration, Sugandha says that nothing happened (i.e. Mudit still presumably had erectile dysfunction) on the first night or their honeymoon and then, they simply got busy with their lives. And one fine day, it simply happened, even as the whole family was busy in a pooja (prayer ceremony).
