AZHAGIYA THAMIZH MAGAN Story
Guru Moorthy (Vijay) is an athlete and business management student. Abhinaya (Shriya) is the daughter of a business baron (Ashish Vidyarthi). They meet and fall in love.
The movie goes on to show how the lovers manage to get the permission of their parents. In the meantime, a different dimension in the tale is revealed while the romantic drama is unfolding. Vijay visualizes some bizarre scenes inside his mind. The scenes are disturbing; and worse, they become true in real life.
A psychiatrist (Dr. Rudran) confirms that it is Extra Sensory Perception power and says that the imageries visualized by Guru would actually happen sooner or later. Unfortunately Guru visualizes another scene where he stabs Abi in the stomach. Sensing that he poses a danger to his sweetheart, he runs away from her to Mumbai.
In Mumbai he stumbles upon a person who looks like himself. This gives him a different meaning of the horrible incident visualized by him. Before catching the man, also played by Vijay, Guru gets himself into an accident. In the meantime, the new man moves to Chennai.
Stylish and carefree Prasad, the Guru look-alike, is a greedy person who does anything for money. He is a womaniser and enjoys life. He meets Dhanalakshmi (Namitha) during his travel to Chennai and has sex with her and escapes from her. Abinaya mistakes him for Guru and brings him to her house. Sensing his opportunity, Prasad decides to act as Guru and intends to marry the rich Abhi.
The real Guru comes back and tells everyone the truth. But no one is ready to believe him, as he is outplayed by the wicked Prasad at each and every move. Finally the truth prevails, but not before a tense battle between the two. During the battle, when Guru tries to kill Prasad, he accidentally stabs Abhi. Guru tries to take Abhi to the hospital but Prasad knocks him out and changes into Guru's clothes so he will look like Guru in front of Abhi. Abhi recovers at the hospital and thinks Prasad is Guru again. At the hospital she tells him how much she hates Prasad and how much she loves Guru. When Prasad hears this he feels guilty for what he did and tells her he is not Guru. Guru suddenly comes into the room, and Prasad leaves as a reformed man.
As Prasad walks away from the hospital, Dhanalakshmi appears saying she is pregnant and its twins. Prasad and Dhanalakshmi join together.
