Shiva and Deva are identical twin brothers. Deva, the elder, is deaf-mute; but he is an expert at lip reading, and the head of a successful advertising company. Shiva loves and trusts his brother. Shiva falls in love with Priya, who wants to marry someone who is an ex-smoker, ex-drunkard, and got ditched by a girl but is pining for her. Learning this, Shiva, with the help of his friend Vicky, invents a romance between him and a certain Sona, and wins Priya's love. Soon Priya realises Shiva's trick and breaks up with him. He tries to tell her that he only cheated and lied to her in the old romance story, but he truly loved her. One day, Priya comes to Shiva's house and slaps him, but eventually she reciprocates his love.
Meanwhile, Deva chances upon Priya and lusts for her. His obsession continues even after his brother marries her and he devises various means of getting close to Priya and keeping Shiva and her apart. Some of the methods Deva uses to woo Priya are masochistic (wounding his hand by the running car engine to stop the couple's wedding night) and psychotic (repeated attempts to murder his brother).
While Shiva is away at work as a substitute for his injured brother, Priya looks after Deva. Priya soon realises the intentions Deva has towards her, but Shiva refuses to believe her and has complete trust in his brother. He even goes as far as to take Priya to a psychiatrist. To get away from it all, Shiva and Priya go on a long-delayed honeymoon, but Deva shows up there. Shiva watches Deva touching Priya's dress and kissing her photo and he realises that she was right all along. Deva beats up Shiva, packs him in a gunny bag, and throws him into a lorry.
Deva disguises himself as Shiva and tries to seduce Priya. Shiva calls her to warn her that Deva is there but Deva picks up the call. She thinks that Shiva told Deva where they are and the one on the phone is Deva's assistant Sudha who called her to tell that Deva might injure himself to disturb their honeymoon. She takes off the phone's wire so that he will not call them back. Shiva then hastens to the house to save Priya from Deva.
Soon, Priya learns that he is Deva and escapes from him, then shoots him with a revolver. Deva falls into the nearby pool unconscious, and when Shiva comes, Priya narrates the whole incident to him. He hugs and apologises to her for not believing her earlier, for taking her to the psychiatrist without knowing the truth and for trusting Deva without knowing his intentions towards her. Suddenly, Deva regains consciousness, but Shiva kills him with the revolver. In the afterlife, Deva talks about his inability to express his feelings for Priya because he was mute.
