When Lalita grows up, she meets Ravi(Govinda) in the college. Both of them fall in love. Ravi's uncle advocate Dharam Das(Kader Khan) agrees for the marriage of the two lovers but puts a condition too. He says that the marriage will take place only when Lalita passes in her examination with good marks. Lalita requests Prof. Vijay Chowdhary, the newly appointed teacher, to give her tution. He agrees.
