Siblings Raju and Laxmi are orphaned at a very young age. Raju is in love with fellow-collegian Parul, whose marriage to Police Inspector Suryadev Singh has already been arranged. When Suryadev finds out about Raju, he arrests and imprisons him on a false charge while arranging a forced marriage with Parul. Laxmi helps Raju escape but when they reach the wedding site, they find that Parul has consumed poison and killed herself. Suryadev then sexually assaults Laxmi, leaving her mentally unstable. Raju goes into hiding in a small village, taking Laxmi with him and changing his name to Birju. Lovely village belle Bijli is attracted to him and wants to marry him, but Raju's only concern is his insane, now visibly pregnant sister. He is about to discover that his troubles aren't over yet.
