Raj Malhotra is a product engineer for Voice Mobiles, a mobile manufacturing company. Junior lawyer Priya goes to Raj’s house for an interview, mistaking him for barrister Ram Chautrani, a neighbour and Raj’s friend. They fall in love, marry and are soon expecting a child as well as Raj’s promotion to CEO. Company chairman Roy arrives with a new and much younger wife, Sonia; after some discussion between the couple, Sonia is named as the new chairperson, Raj’s friend Rakesh as the new CEO, and Raj is placed on the board of directors. At a party, Raj and Priya learn about Sonia and gossip about her attractiveness and her age difference with Roy. Raj jokes that his magnetic personality was responsible for his prestigious promotion. It is implied that Raj may have encountered Sonia previously.
A flashback explores Raj’s previous relationship with Sonia, five years earlier. Raj and Sonia (then a model) meet at a beach in Cape Town. They fall in love and move in together. Sonia becomes pregnant with Raj’s child, which makes him happy, but Sonia refuses Raj’s marriage proposal. She says that she is going to terminate the pregnancy as a child would stand in the way of wealth, fame, power and status; as a consequence, their relationship ends.
After their promotions, Rakesh tells Raj about a defect in the company’s new mobile handset, which causes calls to be simultaneously placed to two people—the intended recipient and another random person from the phone’s contact list. Raj needs Sonia’s permission to stop production, and she invites him to her house to discuss the matter. Sonia makes provocative and sexually explicit statements to Raj, who ignores her. She then aggressively tries to pursue Raj, who resists. Although he repeatedly rejects her advances, Sonia continues trying to seduce him. As he leaves, Sonia threatens to punish him for spurning her. The next day, he learns that Sonia has told her husband that he sexually harassed her. Since he has admitted finding Sonia attractive, his claim of innocence is not believed, and the company pressures him to resign.
Raj asks Chauthrani to take his case; Chauthrani tells him not to resign, and to continue going to work. The case goes to court, gaining widespread media attention with the bulk of the evidence against Raj. Raj’s bank manager returns from overseas with a tape that recorded Raj’s encounter at Sonia’s house. The tape is proven genuine, but is destroyed when Chauthrani is struck by a car driven by a goon who Sonia hired. When Priya asks Raj why he called their bank manager from Sonia’s house, he replies that he had called Rakesh, and the call also went through to the bank manager due to the defect in the company handset. Due to Chauthrani’s injury, Priya continues the case and exposes Sonia’s earlier relationship with Raj in Cape Town. She then plays Rakesh’s voice mail to the court, showing what occurred between Raj and Sonia. It is revealed that Sonia married Roy for money, power, and status, but when he could not satisfy her sexually, she tried to resume her relationship with Raj. Priya wins the case and Roy leaves Sonia. Guilt-stricken and humiliated, Sonia commits suicide by jumping from a building. The end credit scene shows Raj and Priya walking their child.
