Narayan Shankar (Amitabh Bachchan) is the strict headmaster of Gurukul, a prestigious all-boys university. Narayan wants the best out of his students, and places emphasis on tradition, honor and discipline. He has run the university for 25 years and over that time, he has forbid the students from any kind of romance — anyone he catches falling in love will be expelled. The film focuses on three of the school's students: Sameer (Jugal Hansraj), Vicky (Uday Chopra) and Karan (Jimmy Shergill) who all fall in love. Sameer is in love with Sanjana (Kim Sharma), his childhood friend. Vicky falls for Ishika (Shamita Shetty), a student at the all-girls university next door to Gurukul. Karan becomes smitten with Kiran (Preeti Jhangiani), a girl he sees one night at a train station. All three know that if they're caught they'd be expelled, so they at first do not pursue their love interests. Raj Aryan (Shah Rukh Khan) joins Gurukul as a music teacher. He challenges the status quo and slowly introduces changes that Narayan dislikes. Raj is a strong believer of love, and when he learns the stories of the three boys, he encourages them to follow their hearts. The boys take his advice, but are disappointed: Sameer discovers that Sanjana has a boyfriend; Vicky only makes Ishika dislike him when trying to woo her; Karan learns that Kiran is married to a pilot who is assumed to be dead. Raj tells the boys to not be disheartened, and tells them that his love, Megha (Aishwarya Rai) is dead, but he continues to love her and imagines that she is still by his side. Raj encourages the boys to continue to stay loyal to their loves.
