Two college students, the slum child Raja and the dean’s daughter Roja, chat with each other over the Internet and fall in love. However, Roja is engaged and Raja cannot bear to disrespect her father, to whom he owes his livelihood.

Raja (Kunal) is from a very poor, illiterate family, from Tamil Nadu (in the Hindi version he is from Allahabad). People from his region consider that “education is meant only for the rich”. There, poor boys are made to work from age 5, either at factories or farms, so that they can support their families. But, Raja’s mother forced his father to let Raja study up-to class 2, without any work. But he refuses to fund him, and orders him to start work as accountant for their landlord. Raja’s dad is violent and an alcoholic. He spends the family’s income on alcohol. Raja’s family struggles to work hard everyday. Raja’s mom begs him to move to Mumbai to start a new life. Raja heeds his mom’s pleas and moves to Mumbai to attend Ramachandra Institute of Management Studies, the top-most premier b-school in India. The movie starts off at a train station on New Year Day, 1999. Raja talks with a person (Manivannan in the Tamil version, Anupam Kher in the Hindi version) who was well-wishing him. Due to insistence, Raja goes into a flash back. 3 years ago, he reaches Mumbai, where he plans to get admitted into the prestigious Ramachandra College of management, one of the most premier institutes in the nation.
