In front of the eyes of Singh and Mahesh, a robbery took place and Mahesh's parents who were bank employees were killed. Singh never got to know what happened to Mahesh.
Nevertheless, Singh tracks Munna and asks him to surrender. Munna tells him that he has to save his love Mohini (Madhuri Dixit) from the clutches of dreaded gangster Lotiya Pathan (Kiran Kumar). He reveals that he shifted to Bombay (now Mumbai) with his sister Jyoti (Suparna Anand) after the incident. He met a girl named Mohini and fell in love with her. Mohini's father Shyamlal (Anupam Kher) didn't like this relationship. Shyamlal was a drunkard who mooched off the money earned by his dancer wife (Suhas Joshi). When she finally stood up to him, Shyamlal burned her face withsulphuric acid. She died soon afterwards, following which Shyamlal forced Mohini to follow her mother's steps.
Shyamlal has taken a loan from Lotiya and the only way to repay it is to make Mohini dance. But Mohini does not give up and continues meeting Mahesh.

Chote goes to Mahesh's house and tries to rape Jyoti as revenge. Mahesh averts this and kills Chote. Mahesh is arrested and sentenced to one year in jail, after which he becomes Munna and gets exiled. Shyamlal traps Mahesh along with Guldasta (Annu Kapoor), a local tea vendor and sends the duo behind bars for six months for trespassing with intention of robbery. After serving his sentence, Mahesh goes away and becomes a rowdy. On learning the whole story from Munna, Singh allows him to complete his task.
As a revenge, Lotiya kidnaps Mohini. Shyamlal now deals with Munna to get Mohini rescued. Mahesh rescues her, but she is shocked to see that Mahesh is sending her back to her father.
After saving Mohini, Munna surrenders unconditionally to Singh, whereupon he gets arrested and sent to prison. After a retrial, Munna is acquitted of his charges and plans to start a new life atGoa.
