Cupid's arrow and a lot more strike at Madhav Shastri's (R. Madhavan) when he first has a glimpse of beautiful Reena Malhotra (Diya Mirza). Thereafter he meets her again and finds out that she the bethrothed of one Rajiv, and so he impersonates Rajiv and enters Reena's life. And they both fall in love. Then American-settled Rajiv Shyamrao (Saif Ali Khan), who used to know Madhav from college, comes to India to marry Reena. Reena is shocked to find out that the one she has given her heart out to is a fraud and a fake. Accordingly, she decides not to do anything with him, and let her parents (Maya Alagh and Navin Nischal) go ahead with the arranged marriage with Rajiv (or Sam). This devastates Madhav (or Maddy) and he plans to go to America, and start life anew. He also confronts Reena, but Reena refuses to have anything to do with him.
