Shubh Mangal Saavdhan is a 2017 Indian Hindi-language romantic comedy drama film. It is directed by R.S. Prasanna and produced by Aanand L. Rai. It stars Ayushmann Khurrana and Bhumi Pednekar.
Plot: The story is about Mudit Sharma (Ayushmann Khurrana), a Gurgaon boy with a marketing job, who falls in love with Sugandha Joshi (Bhumi Pednekar). 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. A formal marriage proposal is exchanged between their families.
Incidentally, 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 insinuates 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. Now deeply in love, when Sugandha hears him say no to tying the knot, it leads to a heated argument between them. Sugandha leaves saying that she would be waiting for him and his baaraat (wedding procession).
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, suddenly realizing, that the well-wisher is none other than Sugandha's father.
When Mudit and his future father-in-law consult a veterinarian, the doctor simply tell them that it's all because of stress. A day prior to the wedding, Sugandha and Mudit try getting intimate one more time, egged by relatives from both sides of the family. When they exit the room some time later, they find every family member waiting expectantly about Mudit having done 'it'. Mudit says that he managed to perform but Sugandha refutes his words. The families are now deeply worried.
As the hour of the wedding approaches, Mudit understands the true meaning of reaching manhood and risks his life to stand up for the love of his life, Sugandha, and the two are finally married.
In the closing narration, Sugandha says that nothing happened 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).
