Murli Prasad Sharma AKA Munna Bhai, is a goon. A good-natured don in the Mumbai underworld. Given that his father had wished him to be a medical doctor, he creates the faux Sri Hari Prasad Sharma Charitable Hospital and pretends to live in accordance with this wish whenever his parents visit him in Mumbai. One year, however, Munna's plan goes awry when his father meets an old acquaintance, Dr. J. C. Asthana and the two older men decide to betroth Munna to Asthana's daughter, Chinki. At this point the truth about Munna is revealed. Asthana insults Munna's parents for being ignorant of Munna's real life. Munna's father and mother, aghast and later heartbroken, leave for their village. Munna, in grief and despair, decides that the only way to redeem himself and gain revenge for the humiliation suffered by his father at the hands of the spiteful Asthana is to become a doctor. He decides to go to a medical college to obtain an MBBS degree.
