Ishaan is an 8-year-old boy residing in the bustling city of Mumbai, facing numerous challenges in the academic environment. His struggles are often misunderstood, with many labeling him as a troublemaker who simply dislikes learning. This misjudgment has led to Ishaan repeating the 3rd standard due to his previous year's academic failures. His artistic talents and vibrant imagination are overlooked, leaving him feeling isolated. Ishaan's father, Nandkishore Awasthi, is a high-powered executive with high expectations for his sons, and his mother, Maya Awasthi, a devoted homemaker, feels guilty for her inability to help Ishaan despite her deep love for him. Meanwhile, his older brother, Yohaan Awasthi, excels academically and athletically in tennis, further emphasizing Ishaan's feelings of inadequacy.
One day, Ishaan's parents are summoned by the principal, who expresses concerns regarding Ishaan’s behavioral issues and poor grades. The principal suggests they consider special schools, but Nandkishore dismisses this idea and chooses to send Ishaan away to a boarding school, a decision that frustrates both Maya and Yohaan. At the boarding school, Ishaan experiences profound loneliness, suffocating under a harsh environment that heightens his anxiety and depression. His only solace comes from his friendship with Rajan Damodaran, a physically disabled boy who excels in academics and is a fellow student at the school due to his father's role on the school board.
In a moment of despair, Ishaan contemplates taking his own life, but Rajan intervenes just in time, enlightening him that the abusive art teacher, Mr. Holkar, has been replaced. Enter Ram Shankar Nikumbh, played by Aamir Khan, is a new, optimistic art instructor at the school, whose teaching philosophy starkly contrasts with that of Mr. Holkar. Upon recognizing Ishaan's difficulties in class, Ram investigates further and soon discovers that Ishaan is struggling with dyslexia, a fact that has never been addressed by his family or teachers.
Ram takes the initiative to visit Ishaan’s home in Mumbai, where he uncovers Ishaan's hidden passion for art. He then attempts to explain to Maya and Yohaan the challenges posed by dyslexia, showing them how it impacts Ishaan's ability not just with letters but also in physical activities like sports. Sadly, Nandkishore dismisses Ram's explanations as mere excuses for laziness, causing friction and frustration for Ram.
Returning to school, Ram sheds light on the topic of dyslexia during class, sharing stories of successful dyslexics to inspire Ishaan. He becomes a mentor to Ishaan, gaining the principal’s approval to tutor him personally. Through dedicated and specialized teaching methods, Ram helps Ishaan enhance his reading and writing skills, and gradually, Ishaan's academic performance and spirit begin to flourish.
As the school year progresses, Nandkishore eventually acknowledges Ishaan's difficulties after witnessing his efforts to read from a whiteboard. Embarrassed and remorseful, he realizes the depth of his misjudgment regarding his son. The culmination of the school year brings an arts and crafts contest organized by Ram, which is judged by esteemed artist Lalita Lajmi. In an inspiring turn of events, Ishaan’s artwork achieves first prize, while Ram's portrait of Ishaan secures the runner-up position. The principal recognizes Ram’s contributions to the school by making him the permanent art teacher.
On the final day of school, Ishaan's parents meet with his teachers and are left speechless by his transformation. Overcome with emotion, Nandkishore expresses his gratitude towards Ram. As Ishaan runs to Ram for a jubilant farewell hug, Ram lifts him up high and encourages him to return for another year, symbolizing the profound bond they have formed through their journey together.
