Sakthi (also known as Shankar, Vishal Krishna) is a forest ranger in India. His girlfriend Rupa breaks up with him and moves to Bangkok, Thailand. Three months later, Shankar receives a letter from Rupa stating that she still cannot forget him and asking him to meet her in Bangkok and reconcile. Shankar travels to Bangkok. At the airport, he befriends Maya (Trisha Krishnan), a woman who works there.
After arriving in Bangkok, Shankar waits for Rupa at the location mentioned in the letter, but she never shows up. After several days of waiting, he gives up and decides to spend some time sightseeing before returning to India.
One day, Shankar is attacked by a group of gunmen but is rescued by another group of men, who claim that he is their boss and that they are his bodyguards led by his secretary, Madhu. Confused, Shankar insists that he is merely a middle-class man from India and has neither a secretary nor bodyguards. However, after seeing a magazine featuring his photograph on the cover identifying him as a wealthy business tycoon also named Shankar, he assumes that the situation is a case of mistaken identity.
Shankar attempts to prove his identity to Madhu by showing his passport, only to discover that it is a Thai passport belonging to the tycoon Shankar. He also finds the tycoon's wallet in his pocket, containing several premium bank cards. Suspecting that he is the victim of a conspiracy, Shankar struggles to understand what is happening. Over the next few days, he is forced to live the life of the tycoon Shankar arranged by Madhu, including staying in a luxurious hotel suite and attending high-profile business meetings.
Shankar later contacts Maya for help, and the two visit a police station to file a complaint. However, even the police officers believe that he is the tycoon Shankar and treat him like a celebrity. They then visit a bank to confirm his identity. To their surprise, Shankar not only has millions of dollars in his bank account, but his signature also matches that of the tycoon, allowing him access to the account. This further convinces Shankar that he has been deliberately trapped.
Back at the hotel, an employee secretly slips him a note reading, "You are in a trap. Get out soon." Convinced that his suspicions are true, Shankar decides to return to India without uncovering the truth behind the conspiracy.
As Shankar prepares to leave, Maya is attacked by a group of men. He intervenes and saves her, after which he changes his mind about leaving, believing that Maya will continue to be targeted if he escapes alone. When Shankar returns to the hotel, he discovers that the entire setup — including the people and locations connected to the tycoon identity — has vanished. He assumes that those behind the conspiracy have abandoned the operation after believing he had escaped.
Later, Shankar encounters Madhu on the street and discovers that he is actually a pimp. Before Madhu can reveal any useful information, he is shot dead by unknown assailants. Shankar then meets Rupa again, but she denies sending him the letter and refuses to reconcile with him. Realizing that the conspiracy is far more dangerous than he initially believed, Shankar once again decides to return to India despite Maya confessing her love for him. However, Maya is kidnapped by the same group of men before he can leave, forcing Shankar to rescue her again.
It is eventually revealed that the conspiracy was orchestrated by businessmen Rajesh Arunasalam (Manoj Bajpayee) and John Frederick (J. D. Chakravarthy). Bored with ordinary gambling, the two wealthy addicts have turned to "human gambling", in which they manipulate the lives of unsuspecting victims and bet on the outcomes, such as whether the victim will become insane or commit suicide.
Maya is revealed to be one of the participants in the game. Their scheme involving Shankar was designed to make him fall in love with Maya before ultimately having his heart broken by her. Unknown to Maya, Rajesh and Frederick had additionally placed a bet on whether Shankar would kill her after discovering the truth.
As Shankar grows closer to Maya, Rajesh and Frederick introduce another participant into the game: Rohit, a man claiming to be Maya's long-lost boyfriend. Feeling betrayed, Shankar accidentally kills Maya, resulting in Frederick winning the bet.
After the game concludes, Rajesh and Frederick host a celebratory party. While driving home afterward, they are shocked to see Maya — supposedly dead — standing in the middle of the road. Terrified, Frederick sharply turns the steering wheel, causing a car accident.
The two later awaken inside an unfamiliar house, where they are confronted by Shankar and a very-much-alive Maya. It is revealed that after Madhu was killed and Maya became the conspirators' next target, several participants in the game began fearing for their own safety and secretly exposed the truth to Shankar. Shankar subsequently pretended to remain trapped while turning the conspirators' own scheme against them. The defecting players ultimately kill Rajesh and Frederick.
