Balu is a US-born care-free boy. He dropped the course that he was doing because he was missing home and didn't wanted to carry on with his course. His dad tells him off for dropping the course, as he want his son to be like him. He and his dad argue with Balu over every matter, as their points of view don't match. Meanwhile, Swapna, born in India, moved to the US and is Balu's neighbour. She doesn't know English so she doesn't speak when she is outside home, so everyone in the area thinks she is mute and can't speak. When Balu sees Swapna he tried to talk to her but she doesn't reply. He follows her, as he wants to talk to her and want to know her name. One day in the temple where both family was present, Balu sees Swapna talking. One day Swapna tells him that she loves him and want to be with him forever, he also says that he loves her too. But their families dislike one another, as Balu's dad feels Swapna's family is a low class Indian family who don't know how to live in the US. When they find out about Swapna and Balu's love, they both get separated by their family. In order to convince Balu and her family, Swapna tell them that they will have a contract which will say that if Balu and Swapna see or talk to each other in a year's time which includes no texting, e-mail, or messages, their family can get their marriage where ever they like. Balu moves to New York for a job, where he meets Sandhya his boss; she is very strict but a nice person. She lost her love and father on same day in car accident, but she didn't move on in her life and still loves her dead lover. Swapna's cousin who likes Swapna comes to the US and wants to marry her. Swapna's mom wants the same, but can't get her married due to the one-year contract. Swapna's cousin creates a misunderstanding and tells Balu that she is marrying him and shows some fake engagement photos. Balu believes him and breaks down and starts dating Sandhya. Swapna's cousin creates the same misunderstanding by telling Swapna that Balu is to wed, but Swapna doesn't believe it. One day Sandhya finds Swapna and Balu's video on his phone and pay a visit to Swapna without telling her that she will soon marry Balu. Swapna in excitement tells Sandhya how much she loves him and their love story. She also tells her that people believe he is marrying another girl, but she doesn't believe as she trusts Balu and will wait forever. Sandhya, who has lost her love before, goes back to New York and tells Balu that it was all misunderstanding, and Swapna still loves him as much she did before and she is waiting for him to return so he should go back to her. After a year when Balu returns, both families break the contract and say that they will not let this marriage happen. Balu and Swapna jump off a waterfall in front of their parents, telling them that if they can't let them live happily they rather die. Swapna and Balu's parents believe that they are dead but the truth is that they came out live from waterfall and ran away so they can live together.
