Krrish

The film commences with a twelve-year-old Krishna Mehra undergoing an intelligence quotient test by a professor, who suspects his family have superpowers. Krishna answers all the questions correctly, just as his grandmother Sonia (Rekha) fears, and she takes the young Krishna to a remote mountain village in northern India to conceal his unique abilities. Krishna is abandoned by most of his friends, who believe him to be "weird". There he stays for many years running around the mountainside, racing against horses and developing more abilities. Years later, however, Krishna (Hrithik Roshan) meets camper Priya (Priyanka Chopra) and her friend Honey (Manini Mishra), and they soon become friends after Krishna saves Priya from a hang glider accident, much to the bewilderment of the camping group. Krishna and Priya grow close just before she departs, but Krishna has the stronger feelings of love.
Back in Singapore, Priya and Honey are fired by their boss (Archana Puran Singh) for illegitimately taking an extra five days of holiday leave. However, Honey suggests bringing Krishna to Singapore and making a television program about him. Their boss sees potential in this plan and revokes her previous decision to get rid of them. Aware of Krishna's love towards her, Priya tells Krishna that she loves him to encourage him to join her in Singapore.

The news is taken badly by Krishna's grandmother, who protests that people will want to take advantage of his abilities. She then explains that his father Rohit was hired to help design a machine to see the future by Dr. Siddhant Arya (Naseeruddin Shah) in order to prevent wars and help prepare against natural disasters. But on the night of Krishna's birth, Rohit claimed to her that he was being used. Rohit reportedly died in a laboratory accident that night, with Krishna's mother dying shortly after of a broken heart. Krishna promises his grandmother that he will never reveal his powers, to which Sonia eventually relents and permits him to go. In Singapore, during the production of the television program, Krishna keeps his word. With the program revealing nothing exceptional about him, Priya and Honey are once again fired.

Krishna later meets with Kristian Li (Bin Xia), who is attempting to raise funds to pay for his young sister's leg surgery. He invites Krishna and Priya to the Great Bombay Circus, but during the performance a firework explodes and ignites the tent, which is swiftly evacuated. However, several children remain trapped in the blaze, and Krishna is faced with the dilemma of saving the children without revealing his abilities. He dons a broken black clown's mask and puts his jacket on inside-out, creating the persona of Krrish.

Later, Kristian sees Krrish fighting some goons and removing his mask. He is shocked to learn that his friend Krishna is Krrish. As Krrish is being offered a reward for his deeds, Krishna asks Kristian to assume the identity, so that he can pay for his sister's surgery.
