Manoj 'Manu' Sharma (R. Madhavan) is a NRI doctor living in London. He comes to India to find an Indian bride and get married. The day he arrives, he is taken to Kanpur by his parents and his friend Pappi (Deepak Dobriyal)to meet Tanuja 'Tanu' Trivedi (Kangna Ranaut). While at Tanu's house the parents talk and decide they like family very well and if Manu likes Tanu they should officialise the relationship the very same day. But before anyone can meet Tanu, her mother tells Manu's family that she was ill since yesterday and asks if Manu would mind going up to meet her. While Manu talks to Tanu, who seems shy and quiet behind her Ghoonghat, Manu realises that she is in fact asleep. Yet he likes her, and tells both the families that he is willing to marry her. Soon after the families go on a pilgrimage, and during the train ride Tanu takes him away from their family members, and confesses that she had intentionally taken five tablets to fall asleep so as to be rejected by him. She tells him in rather rudely that she loves someone else, and that she has his name tattooed on her chest; she also tells him the thugs who had roughed him up when he initially came to Kanpur were sent by her boyfriend. She demands that Manu rejects her. Manu considers the odds, and though he likes her, he asks his father to announce that he cannot marry her.
