In India gangsters are called Bhai (brothers). One such Bhai is Shri Hari Prasad Sharma alias Munna, he is feared by everyone in Mumbai, a big city in India. Munna is a full-time vagabond and later cons his village-based parents into believing that he is a doctor, which they wanted him to become, finding him fulfilling there dreams, they decides to pay him a visit in order to verify for themselves that he is indeed a doctor. He gets a nasty shock when he hears they are coming so he transforms a rooming shanty house into a makeshift hospital, populated by patients, people he beats up. His parents arrive, are pleased, and happy that their son is well settled and assure him success and bless him. They would like him to get married to his father's friend Dr. Asthana daughter. The marriage is arranged, but before the engagement, Dr. Asthana finds out the truth about Munna, and revealed his true identity to the public and his parents. After learning the truth Dr. Asthana cancels the marriage. Being humiliated by the public for Munna's deeds his parents are very much hurt and return to there home, leaving Munna with a strong desire to hurt the doctor - and force him to let his daughter get married to him - even if it means getting admitted in the medical college - with forged documents which might as well leads to escalating the conflicts to an extend that it will be hard to solve.
