Satish Kumar is the only heir to a vast estate, managed by his uncle Udaybhan Singh. Udaybhan has conditioned Satish from childhood to be afraid of him, and this fear persists into Satish's adulthood, leaving him unable to stand up for himself.
Satish is devastated to learn that his wife Aarti had married him only to rob him of cash and jewels. Aarti is thrown out by Udaybhan, but Satish goes after her and they reconcile. Udaybhan kills Satish and convinces the police it was suicide. Aarti swears vengeance via Satish's unborn son whom she is pregnant with.
Years later, Udaybhan is now living with his son Chandrabhan in the mansion formerly owned by Satish, when Aarti and her grown son Avinash surface again. Avinash files a court case to prove his paternity from Satish, but due to an outburst in court is jailed briefly. Avinash's girlfriend Neena gets Chandrabhan drunk and records him on audio admitting that Udaybhan killed Satish.
Avinash plays the recording to Udaybhan in an attempt to make Udaybhan confess to the police, but Udaybhan kidnaps Neena instead and Avinash has to rescue her. Avinash then kidnaps Chandrabhan to make Udaybhan confess, but Udaybhan kidnaps Aarti and Neena and also kills Avinash's aunt. Udaybhan arranges with Avinash for a hostage exchange. After getting back Chandrabhan in the exchange, Udaybhan attempts to kill Neena and Aarti. A huge fight scene ensues, during which Chandrabhan and all their henchmen are killed. Avinash kills Udaybhan with the same knife that Udaybhan killed Satish with, thereby completing Aarti's vengeance. Avinash and Neena celebrate romantically.
