This is the story of one man, his family and how they overcome the obstacles that life puts in their way, together. It is the story of human spirit and how it ultimately prevails.

Rajveer Singh (Saif Ali Khan) is a pit-crew worker in a racing team with a passion for driving who gets discovered by a team manager, Harry (Jaaved Kaaferi). The same day he accidentally meets a music student, Radhika (Rani Mukerji), who he falls for instantly.

He gets drafted into Speeding Saddles; - a failing race team and transforms from Rajveer Singh to RV - the racecar driver. While his racing career takes off instantly, his love life also blossoms after a whirlwind romance. A few months later, he is both a happily married man and of the country's best racers. Fatherhood and greater success both follow and soon he is the Number 1 racecar driver in the USA, as well as the proud father of two precocious kids - Priya (Angelina Idnani) and Ranveer (Ali Haji).

But as a result of a bad-racing accident, RV is hospitalized for a few months. When he tries to make a comeback, he realizes that he has been mentally scarred by the accident and has lost his edge. His life now takes a turn for the worse and after a string of failures, he forced to auction his house and move with his family to run-down Bronx- style neighborhood. However, RV and Radhika decide not to tell their children the truth and construct a skillful masquerade of a reality show where they have to live a poor life in order to win a mythical grand prize.

The family struggles to survive a life that they are not used to, using a mixture of fantasy and cheerfulness to pull through in the face of adversity. But an incident forces RV to reclaim the life that was taken away from him.

Can he, once again and perhaps for a last time, face down his inner demons on the racetrack? Can the family remain together in the wake of what could perhaps be their biggest challenge yet?
