|Three young men arrive at a train station during a night and strike an instant friendship. They are all going to join a famous Indian private school, 'Gurukul'.|
Gurukul is run by a stern headmaster named Narayan Shankar (Amitabh Bachchan). He is a strict disciplinarian who believes his institute runs because of his principles, rules and disciplines. Apparently the students are picked from universities all over the country to study at Gurukul and the headmaster has high expectations of them. The headmaster has instituted a strict anti-romance policy. He says that students who become romantically involved will be expelled.
The three friends all have their hearts set on different girls. Sameer (Jugal Hansraj) works in a cafe and is in love with his childhood friend Sanjana (Kim Sharma). Unfortunately for Sameer, she already has a boyfriend. Vikram (Uday Chopra) catches Ishika (Shamita Shetty) stealing apples from the Gurukul gardens, and falls in love at first sight. Karan (Jimmy Shergill) sees Kiran (Preeti Jhangiani) when he is waiting for a train. Kiran is married to an Army Officer who never returned from war. She behaves as if her husband were still alive because of her father-in-law, General Khanna (Amrish Puri) who holds hope that his son is alive. They all give up hope of taking their romance to the next level, for the fear of Narayan Shankar and his stern ways.
The pupils soon meet Raj Aryan Malhotra (Shahrukh Khan). With flowers and a violin in his hand, Raj wants to join Gurukul as a music teacher. After some reluctance, Narayan Shankar allows Raj to join the institute. Raj teaches music, spreads the message of love amongst the 3 men, and encourages them to follow their hearts and fall in love.
Raj tells the 3 students of a man who loved a woman named Megha (Aishwariya Rai) who was forbidden to love him due to her father,Narayan Shankar. Due to this, she committed suicide by jumping off her bedroom balcony. Nevertheless, Raj continues to love her. The audience gets a glimpse of Megha, who lives in Raj's imagination and speaks to him when he is alone.
As the boys fall in love, the relationship between the headmaster and the music teacher begins to become strained. Much to the chagrin of the headmaster, Raj begins to implement many changes. He begins hosting parties, inviting girls from the nearby girls hostel, celebrating festivals and encouraging students to break the strict rules.
In the second part of the film, it is revealed that Raj was once also a student in Gurukul, and the girl he fell in love with was none other than the headmaster's daughter, Megha. When Narayan found out he banned them from seeing each other, expelled the boy without seeing him, and distanced himself from his daughter. She became upset and ultimately committed suicide by throwing herself out the window.
This tragic experience inspired Raj to spread love throughout Gurukul, and one day reach out to Narayan Shankar and show him to magic of love and affection.
When Narayan Shankar realizes that Raj is the same boy who was in love with his daughter, he pulls all steps to remove him from the institute. Raj continues to help the 3 boys and their lovers to meet against school rules and the story turns into war between Raj Aryan and Narayan Shankar.
After many events and songs, eventually, Narayan Shankar realises that love and change are indeed important parts of life and softens.
Gurukul is transformed forever into a singing, dancing and loving school.
