 Munnabhai, the light hearted don, this time falls in for a radio jockey Jahnavi, and to meet her, he wins a competition in... well, Munnabhai style! But to woo her, he has to study about Mahatma Gandhi. This brings about a new change in him and he tries to change the lives of people around him using his  Gandhigiri . Whether the teachings of M.K. Gandhi are relevant in today s world or not, and can Munna change his and other s lives for better or not, only  Lage Raho Munnabhai  can tell.
