The film is set in the USA where Shekhar Subramaniam (Shah Rukh Khan) works for a video gaming company called Barron Industries run by Dalip Tahil. Jenny (Shahana Goswami) is a co-worker and so is Jackie Chan (Tom Wu). Shekhar is a South Indian (Tamil) who is married to Sonia (Kareena Kapoor) and their son is preteen Prateek (Armaan Verma). Prateek is a typical school kid who is impressed by mighty villains. He quite dislikes his father's nerdy nature and tries to be 'cool' most of the time. When the boss demands that a new video game be created, Shekhar goes on to create a game that has a dominant villain – Ra-One – who is undefeatable. This is done at his son's suggestion and soon Prateek is enamoured by both the game and his father's skills. Unfortunately, Ra-One has the power to re-invent himself and is keen to get out of the game and kill Lucifier – the nickname that Prateek uses to play the game. He does just that and soon Shekhar is killed. Not knowing the actual situation, Sonia decides to move to India to their family home along with Prateek. Watch the film to see what happens when Ra-One decides to follow Lucifer (Prateek) to India and kill him.
