Gaurav Mehra (Girish Kumar), an obedient guy who stays in London is getting ready for his wedding to Vandana who is dominating and finicky by nature. His friends arrive for the marriage and host a bachelor’s party, which goes awry when a sloshed Gaurav wakes up with a girl Pooja (Navneet Kaur Dhillon). Gaurav being an obedient and well-behaved boy asks Pooja to leave but unable to find her clothes, she ends up wearing a shirt that Gaurav offers which incidentally has been gifted to him by his to-be mother-in-law for his upcoming engagement. He realises the mistake only when Pooja is gone and then starts his search. Though fuzzy about the details of the previous night, he finally meets Pooja who tells him what exactly transpired the night they were together.

Going down memory lane, which is clubbed with numerous lectures by Pooja on how to live life, Gaurav falls in love with the free-spirited girl. But Gaurav doesn’t acknowledge his feelings and ends up marrying Vandana. After a quick jump of four years, Gaurav is divorced and is relentlessly blaming his elder sister (Tisca Chopra) for everything that has gone wrong in his life. To help Gaurav, his friend suggests going to Mauritius for a vacation. For a break, he lies to his sisters saying that he is going for a business trip, whereas he went to Mauritius with his friends. As luck would have it, Gaurav once again meets Pooja.

But now the scenario is reversed; Pooja is all set to get married to Vinayak Sen Gupta, to which she had accepted. They both spend more time together only till Pooja realises Gaurav loves her. She tells him about her engagement and urges him to forget her. Gaurav goes back home and has a fight with his sisters. He goes to meet Pooja at her home when he gets her wedding card in his house. There, he meets Vandana and spoils her makeup as a revenge. He then turns to Pooja and requests her to meet him. They meet after the function is over. Pooja asks him to buy her a whiskey and they both started drinking, only ended up spoiling Pooja's father's pots in the front lawn and sleeping with each other for the second time. Pooja requests Gaurav to leave and never meet her again. Gaurav leaves. At a dhaba, Gaurav notices that the baraat had come back which meant that Pooja broke the alliance. He went back to her and they get together. The movie has a happy ending, with the reunion of the leads.
