Malini (Nithya Menen) is a nursing student in Bangalore with plans of traveling to Canada, Toronto for a career. She meets Varun (Krish J. Sathaar) from the travel consultancy agency working towards setting up her visa. They soon fall in love and start living together. Malini loves him with all her heart and takes their relationship and living together seriously.

One day while at a pub, a guy misbehaves with Malini, and Varun beats him up badly. The guy tries to take revenge on Varun and searches for him. Varun goes into hiding with the help of his boss Prakash (Naresh). Prakash arrives at Varun's home to inform Malini about the situation. Then he asks her plainly "Can I have sex with you?" A shocked Malini is then brutally attacked and raped. When Varun finds out what happened, he becomes violent and wants to kill Prakash. Malini calms him down saying that she does not want to make the incident worse than it is; she instead wants to get to Canada at the earliest. Once Malini recovers from her injuries, Prakash visits her again to ask for forgiveness. He comes while Varun is not around and rapes her a second time. Malini decides not to travel abroad and plans to murder Prakash.

Varun discusses the situation with Prakash, who suggests killing Malini and appoints Varun to do it. Varun traps her by putting some drugs in her bag. The police arrest Malini, and she is imprisoned. While Malini calls out for help, she finds Varun simply walking away from her, which is when she realizes he set her up. Varun relocates to Chennai and runs a modeling agency. While in prison, Malini meets Janaki (Janaki), who is sentenced for murder. Through Janaki's criminal world connections, Malini realizes that Varun is a known pimp and was cheating her along with Prakash's support. Janaki and Malini bond well with each other, and Janaki moulds a criminal mindset within her for the strength and courage needed to strike back at Varun and Prakash.

When the court sets her free, Malini, with the help of DK kills Prakash by poisoning him with a cobra. Next, she arrives in Chennai as a femme fatale in search of Varun while pretending to be a model. Later one night, Malini hooks up with Varun in his studio. Varun, who had recognized her earlier, reveals it angrily berates her. He beats her and abuses her by calling her a "slut who does any 'adjustment' to flourish her career" for stopping her further being a menace to him. But his frustration dissolves slowly as he wants to enjoy her company. He reminds her she is a mere woman.

But at night Malini executes her revenge plan and sedates Varun and sadistically penectomises him. When he regains consciousness she tells him that she has removed his male organ through a medical surgery. While Varun finds himself in intense pain and bound to his bed, she taunts him to make him realize his faults and the gross wrongs he committed to her and rationalizes her crime. But he doesn't yield to her taunts and reveals a backstory concerning his mother and that his life as a pimp is not entirely his fault.

Malini tells Varun that she knows that she is still somewhere in his heart. She reminds him that she has only lost someone who cheated on her, whereas he lost someone who genuinely loved him. Now Varun is stunned that he is not even able to face Malini. Varun recollects that her love was true and his love was overshadowed by his male supremacy concept and greed for wealth. Over the days, he admits his actions that caused her pain. Then Malini leaves him but not before inviting him to settle the score with her, if any remains there. Varun accepts the challenge of a true criminal as he is and taunts her that he will confront her when he is ready, most probably knowing that he has to settle the score with her in terms of true love with roots in violence. Malini leaves for Canada, dismantles her cell phone, and cuts further contact with DK.
