Rajveer Singh (Saif Ali Khan) has an immense passion for car racing and dreams of making it big on the racecourse. After being discovered by his manager Harry (Jaaved Jaffrey), he meets Radhika ‘Shona’ Shekar Rai Banerjee (Rani Mukerji) and instantly falls for her. He joins Speeding Saddles, a failing race team, and transforms from Rajveer Singh to RV the race car driver. He wins his first race and keeps winning, making him quite wealthy.
What started as an innocent love blossoms into a serious relationship as months pass. Radhika is a great pianist, majoring in music at Columbia University, whereas Rajveer has no degree or any education background. His lack of education and planning earns the disapproval of Radhika’s father, Subho Shekar Rai Banerjee (Victor Banerjee). However Radhika leaves her father and marries RV, whom she loves immensely. She forgets about her degree and takes on her job as a wealthy housewife, therefore Radhika Shekar Rai Banerjee turns into Shona. Their family is complete with the birth of two beautiful children, Priya a.k.a. Princess (Angelina Idnani) and Ranveer a.k.a. Champ (Ali Haji (actor)). Luck follows RV and he is soon proclaimed the number one race car driver in the USA.
