Madan Chopra, a wealthy businessman, has two daughters, Seema and Priya. During a car race in Madras, Chopra meets Vicky Malhotra, a seemingly charming young man who allows him to win the race to earn his trust. Chopra becomes impressed by Vicky, and Priya gradually falls in love with him. However, Vicky is revealed to be Ajay Sharma, who has assumed a false identity to take revenge on Chopra.
Seema, who is in a secret relationship with Ajay, faces pressure from her father to marry someone else. Ajay tricks her into writing a suicide note and later pushes her off a building, staging her death as a suicide. To avoid a scandal, Chopra quickly closes the case. Suspicious of her sister’s death, Priya begins investigating with the help of Inspector Karan Saxena, an old college friend.
Her investigation leads to Seema’s friend Ravi who tells Priya that he took a photograph of Seema and Ajay together at a party. Before Priya can see it, Ajay intervenes and forces Ravi to write a suicide note, framing him as Seema's murderer and kills him by hanging him while staging his death as a suicide. Meanwhile, Chopra plans Priya’s engagement to Vicky, still unaware of his true identity.
Through flashbacks, it is revealed that Chopra once worked for Ajay’s father, Vishwanath Sharma. When Sharma caught him embezzling company funds, Chopra was jailed. Upon his release, Chopra pretended to repent but betrayed Sharma when he gave Madan power of attorney, taking over his business and leaving the Sharma family destitute. This led to Sharma’s death from a heart attack, the death of Ajay’s baby sister, and his mother Shobna’s mental breakdown. Witnessing Chopra's cruelty, Ajay vowed to destroy him and only goal in life was to see the destruction of Chopra.
During Priya and Vicky’s engagement, Seema’s college friend Anjali calls the house and Ajay answers the phone. She mentions having seen Seema with a man who resembles Ajay at her birthday party and possessing a photograph of them together, alarming him. Realizing that she could expose his true identity, Ajay visits the hotel where Anjali works. He kills her and eats the photo while concealing her body in a suitcase, which he later disposes of in a river. The next day, Inspector Karan informs Priya that Anjali has gone missing and asks whether any phone call was received from her that day, planting the first seeds of Priya’s suspicion toward Ajay.
Back in the present, Priya meets the real Vicky Malhotra and begins to suspect Ajay. She discovers a locket with photos of Ajay and Seema, confirming her suspicions and confronts Ajay who reveals Chopra's theft of his family's wealth to a shocked Priya who feels sympathy for him despite his crimes. Chopra, becomes aware of Ajay’s identity after giving him power of attorney which Ajay uses to steal his company. Chopra confronts him at his home with goons. A brutal fight ensues, during which Chopra's goons badly beat Ajay and Madan hits Shobha, who regains her sanity upon hearing Madan's voice. In the end, Ajay fights back but Chopra fatally impales Ajay with a rod, but Ajay retaliates, fatally wounding Chopra who dies immediately. A wounded Ajay struggles back to his mother, promising her he has reclaimed everything that was meant to be their's. Now only wanting to rest peacefully in his mothers arms, a despondent Priya and Karan watch as Ajay dies in his mothers arms, finally at peace.
