Plot

Sachin Kulkarni (Prateik Babbar) is a student of mechanical engineering in Mumbai who aspires to become a filmmaker. His friend introduces him to cinematographer Anay (Manu Rishi). With Anay's help, Sachin becomes an assistant director. Sachin's family, who are Marathi Brahmins, rent Jessie Thekekuttu's house. Jessie (Amy Jackson) is from a conservative Malayali Syrian Catholic "Nasrani" family from Alappuzha, Kerala, that lives upstairs. Sachin falls in love with Jessie the moment he meets her. He tries to interact with Jessie, who is afraid of speaking to men around her strict father, and ends up angering Jessie. Unable to hide his feelings for her any longer, Sachin confesses his love for her, to which she does not respond. A few days later, Sachin learns from his sister that Jessie has gone to Kerala to visit her grandmother. He, along with Anay, ends up in Kerala to look for her. After several days, he finds her and apologises. She introduces him to her family in Kerala as her "classmate". Jessie denies she has any feelings for him but agrees to be his friend. On the train journey back home, however, the two get closer and share a passionate kiss. Sachin is convinced Jessie loves him; the two meet several times and Jessie begins to admit that she also likes Sachin, but wants to refrain from any problems because she knows her father wouldn't give her hand in marriage to a Hindu. Consequently, due to various misunderstandings between Jessie's brother and Sachin, her parents learn of their supposed affair. They arrange her marriage with someone else and fix a wedding date. The day arrives and midway through the ceremony, Jessie refuses to marry the groom, displeasing everyone in her family. Sachin, who had, without anyone's knowledge, come to Kerala to witness the wedding, is ecstatic and secretly visits Jessie at her home. It is then that Jessie admits she has indeed fallen in love with him. Sachin and Jessie continue to meet each other without their parents knowing.
