Cast: Aamir Khan, Kareena Kapoor
Farhan Qureshi (R Madhavan) and Raju Rastogi (Sharman Joshi) are students at the prestigious Imperial College of Engineering (ICE) who also share a room at the institution's dormitories. Farhan's passion is wildlife photography, but he pursues an engineering degree to appease his father. Raju chooses engineering with hopes of improving his family's financial situation, but his lack of self-confidence results in poor grades. Their third roommate and friend, Ranchodas "Rancho" Chanchad (Aamir Khan), has an immense interest in engineering, and invents in his spare time. After giving unorthodox answers in class, Rancho faces scrutiny from the college's director, Viru Sahastrabuddhe (Boman Irani), known as "Virus", whose traditional philosophies on education and learning contrast sharply with Rancho's atypical ideas of teaching. Virus is shown to be extremely strict — a trait that indirectly caused his own son's suicide after putting him under excessive pressure.
Rancho eventually falls in love with Pia (Kareena Kapoor), Virus' younger daughter, who is a medical student in residency at the city's hospital. Rancho always scores the highest marks on exams out of his class, much to the dismay of both Virus and Chatur Ramalingam (Omi Vaidya), an arrogant Ugandan-born Tamil student who believes in rote learning, and dislikes Rancho, Farhan, and Raju. One night, Rancho, Farhan, and Raju drunkenly break into the Sahastrabuddhe household to allow Rancho to profess his love to Pia. After discovering their antics, Virus threatens to expel Raju unless he writes a letter blaming Rancho for the break-in. Unwilling to betray Rancho or disappoint his family, Raju unsuccessfully attempts suicide, and ends up in a coma. After intensive care and support from his friends, Raju recovers just before he successfully interviews for a corporate job. Before this Rancho and Pia post Farhan's letter to his favorite photographer. Farhan gets a positive response but fears his father. Rancho then convinces him to go confront his father and his father reluctantly agrees to it.(wiki)
