Both fall in love with each other. When she informs her mother about her love for Raja, she is met with strong opposition, as her mother knows that Raja Babu is already married and has a son.

When Lalita meets with Raja, he admits to her that he is not Raja but his real name is Rajan Ram Bahadur, but refuses to divulge any other information to her. She decides that she will have nothing to do with him. The mystery deepens when Pran Bahadur, the step-brother of Raja Babu returns and wants to confront the young man who has taken over Raja's identity, with results that will change the lives of everyone around them forever.
