3 Idiots' is a light-hearted and entertaining journey of two friends [Madhavan and Sharman Joshi] as they embark on a quest for a long lost buddy. On this journey, they encounter a long forgotten bet, a wedding they must crash, and a funeral that goes impossibly out of control. As they make their way through the perilous landscape, another journey begins: their inner journey along memory lane and the story of their friend - the irrepressible free-thinker Rancho [Aamir Khan], who in his unique way, touched and changed their lives. It's a story of their hostel days that swings between Rancho's romance with the spirited Pia [Kareena Kapoor], and his clash with an oppressive mentor, Viru Sahastrabudhhe [Boman Irani]. And then one day, suddenly, Rancho vanished.
'3 Idiots' is a fresh and unique comedy of ideas that is as provocative as it is funny, as wildly entertaining as it is insightful. A laugh-riot that talks about the most important of human pursuits: self-actualization.
