Rancho, Raju and Farhan enter the elite engineering college, only to learn lessons of life that cannot be taught through books and classrooms. Principal Viru Sahastrabuddhe(virus) is no help at all. 3 Idiots is the perfect end to an exciting year for India: the year when the aam aadmi voted in progress, liberalism, secularism and turned his back to corruption, communalism, regionalism. The three idiots, Rancchoddas Shyamaldas Chanchad(Aamir Khan), Raju Rastogi(Sharman Joshi) and Farhan Qureshi(R Madhavan), are perfect archetypes of the new age Indian who is essentially a non-conformist, questioning outmoded givens, choosing to live life on his own terms and chartering new roads that consciously skirt the rat race. Of course, they begin on the beaten track - due to societal/parental pressure - but refuse to become cogs in the wheel. Naturally, they end up as the Frostian hero(Robert Frost’s Road Not Taken) who made all the difference to his life, and the world, by taking the road less travelled by.
Farhan Qureshi(R.Madhavan) and Raju Rastogi(Sharman Joshi) are students at the prestigious Imperial College of Engineering(ICE). 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’ Shamaldas Chanchad(Aamir Khan), has an immense interest in engineering, and invents in his spare time.Rancho eventually falls in love with Pia(Kareena Kapoor), Virus’ younger daughter, who is a medical student in residency at the city’s hospital. He also scores the highest marks on exams out of his class, much to the dismay of both Virus and Chatur, an arrogant Tamil student who also despises Rancho.
Ten years later, Chatur is the vice president of a corporation in the United States, Farhan is a successful photographer, and Raju is married while living a comfortable lifestyle. None of them have heard from Rancho since graduation, and the three reunite at the college campus water tower to find him.With the help of the real Ranchodas, the trio travel to a village school in Ladakh, where Rancho supposedly works as a teacher. On the way there, the three rescue Pia from her arranged wedding at Manali.
Assuming Rancho to just be a school teacher, Chatur forces him to concede that he is less successful than Chatur. Shortly after, Rancho reveals that he became a scientist(while also teaching young children when he’s not researching), and that his real name is Phunsukh Wangdu. Much to Chatur’s horror, this also happens to be the name of a wealthy client that Chatur had spent a year trying to find and sign a business deal with.
All over the movie was outstanding .according to me till now there is no picture ever hed in the Bollywood history.
