Ishaan Awasthi (Darsheel Safary) is an eight-year old boy who hates school. Every subject is difficult for him and he perpetually fails his exams. He also lacks motor coordination skills and finds it difficult to throw a ball in a straight line. Rather than help him, his teachers and classmates subject him to constant acts of public humiliation. At the same time, Ishaan's internal world is rich with wonders that no one else seems to appreciate: magical lands filled with color and animated animals.

It is no better at home. His father, Nandkishore Awasthi (Vipin Sharma), is a successful and busy executive who expects the best from his boys. His mother, Maya Awasthi (Tisca Chopra), is a housewife who is perpetually frustrated by her inability to help Ishaan excel. Ishaan's elder brother Yohaan (Sachet Engineer) is a successful scholar/athlete, a fact which Ishaan is constantly reminded of. After discovering that Ishaan skipped (or "bunked") school, in addition to having poor grades, his parents decide that he needs to attend boarding school in order to be 'disciplined'.

Life at the boarding school does not help Ishaan to excel, despite being befriended by Rajan Damodran (Tanay Chheda), one of the best students. Instead, he sinks into a perpetual state of fear and depression as he now has to contend with the added trauma of separation from his family. This changes, however, when a new temporary art teacher Ram Shankar Nikumbh or "Nikumbh Sir" (Aamir Khan) joins Ishaan's boarding school. Nikumbh, with his characteristic teaching style that is markedly different that his strict predecessor, soon becomes popular among the students. He begins to notice that Ishaan is unhappy and a non-contributor to activities in the class (despite creating an atmosphere in the class that actively seeks contribution from the students). Disturbed, Nikumbh begins to review Ishaan's past work and determines that all of his "failures" are actually reflective of dyslexia.

On his day off, Nikumbh visits Ishaan's parents and asks to review more of his work. He is also stunned by the sophistication of Ishaan's paintings. Nikumbh tells Ishaan's parents that Ishaan is a bright child who processes information differently than the other children in class. He describes dyslexia to them and clarifies that this is a neurological condition which is not a sign of low intelligence. He also tells them he can provide extra tutoring which will help Ishaan succeed.To support this argument, Nikumbh highlights Ishaan's artistic ability as demonstrated by his many paintings and creative works-of-art. In order to make his point, Nikumbh demands that Ishaan's father read a box with Japanese text. When Mr. Awasthi states that he cannot read the text, Nikhumbh reprimands him. In doing so, Nikhumbh demonstrates to them what Ishaan struggles with on a daily basis.

When he returns to the school, Nikumbh brings up the topic of dyslexia one day in class and offers a list of famous people who are considered dyslexic: Albert Einstein, Leonardo Da Vinci, Walt Disney, Agatha Christie, Thomas Edison, Pablo Picasso, and actor Abhishek Bachchan. As the students are leaving the classroom Nikumbh asks Ishaan to stay back. At that time Nikumbh reveals that he has experienced the same difficulties with dyslexia. Nikumbh also conveys the same information to the principal of the school (M.K. Raina) and asks if he can act as a tutor for Ishaan. After gaining the Principal's assent, Nikumbh then proceeds to teach Ishaan using remedial techniques developed by specialists in the area of dyslexia. Ishaan soon develops interest in language and mathematical skills and his grades improve. Towards the end of the year, Nikumbh organizes an art fair for staff and students alike. The competition is judged by Lalita Lajmi (who portrays herself in the movie). Ishaan, with his strikingly creative style is declared the winner, while his teacher, Nikumbh (who paints Ishaan's portrait) is declared the runner up.

When Ishaan's parents meet his teachers on the last day of school, they are speechless over the changes in him as he has improved in all of his subjects. Before leaving for the holidays, Ishaan runs to hug his teacher. The film ends with a freeze frame shot of Ishaan being tossed in the air by Nikumbh as if he were flying.
