The movie starts off with Latha , a medical student (this itself is a big joke) who wants to do a project on patients with brain damage. Her perusal through the files on brain patients leads her to one 30 year old Ragoo Ramaswamy. Ragoo suffers from anterograde amnesia, a condition wherein a person is not able to convert short term memory into long term, due to some head injury. Ragoo's memory lasts 15 minutes.
Latha expresses her desire of doing her project based on Ragoo’s condition to her professor. The professor tells her that it might not be a good idea, since Ragoo’s case is still an unproven police case, and if she gets entangled with him, then it might prove to be disastrous to her career. Latha gives up her idea, and the storyline switches to Ragoo.
Ragoo is busy bashing up an unidentified person played by Kabaali (cycle kadai). After killing him, Ragoo takes out a set of photographs, and tries to identify him. He takes out the photograph of the person whom he killed and crosses it out. (Into mark)
The police detects the crime and comes out with full force to unearth the murderer. The police officer, played by Suchinder, gets a bus ticket from the scene. On its backside, he notices that someone has written 3/100. He makes a vow that he will get to the person who committed the murder in a few days time.
In the meantime, we get to know that Kabali, whose boss Annachi is worried about the fact that he is the second person killed within a week.
The story again goes back to Ragoo, who uses another set of photographs to get back to his house. He identifies his flats as well as the watchman using Polaroid photographs. He enters his flat in RK Shanmugam Salai, and his house is full of maps and photographs. His daily life is a struggle and we also get to know that his ultimate aim is to kill Annachi. To get to his ultimate aim, he uses photographs and body tattoos to keep track of various events in his life, since he knows that he would forget things in 15 minutes.
Meanwhile, the police played by Suchinder, identifies the conductor of the bus who issued the tickets retrieved from the murder scene. The conductor says that he can identify the person. Suchi manages to get to Ragoo’s flat, and after a surprise attack, manages to overpower him and tie him to a chair.
Our intelligent cop Suchi, starts searching the house. He stumbles on a diary of the year 2002. He opens it to find a photograph of Ragoo as a handsome guy, unlike the present state. He starts reading the diary, and that’s how we come to know of Ragoo's past.
The diary tells the story of Ragoo Ramaswamy, owner of PCO booth and Travel Agency inherited from his father Mr. Ramaswamy. He has huge plans for India, and is busy building a financial empire. The diary also speaks of many girls - one of them is Savitha, a small time ad-model, who is struggling to make it big.
A small confusion by the employees of Ragoo forces Savitha to feign in front of producers that she is the girlfriend of Ragoo. Savitha is able to get better roles and is achieving what she had aspired for, until the news is broken by a magazine. Ragoo is furious to learn about it and goes to meet his so called girlfriend. On the way, he sees Savitha helping a few handicapped children and falls for her, without knowing the fact that she is the girl who has spread rumors about him.
When he reaches the studio where Savitha is doing her shootout, he recognizes the girl. Savitha had not seen Ragoo before and she mistakes him for a struggling poor actor. Ragoo plays along and they become good friends. Many hilarious situations follows and we see that Ragoo is falling in love with Savitha. On New Years eve, Ragoo confesses his love to Savitha, who asks for sometime to tell her decision. Ragoo tries to take her to Besant Nagar.
The diary ends here, and Suchi bewildered for not getting the entire story starts searching frantically for the diary of the year 2003. As he is about to start reading, as Ragoo breaks free and ties up Suchi after some stunt scenes.
With no one after him, Ragoo makes another attempt at killing Annachi, only to kill another of his gang member Madhi, who divulges to Annachi that someone is trying to kill him before dying. Annachi goes about killing anyone who was his enemy including Dravida Mani and Pudur Karna, but still he has an intuition that his attacker is still at large.
Meanwhile, Latha stumbles upon Ragoo and befriends him. On one such occasion, she goes to his flat, and finds it unlocked and unoccupied.
She goes about searching the house, and learn of the murderous intent of Ragoo, she also finds Suchi gagged in one of the cupboards. Ragoo enters the scene, and starts chasing Suchi, who meets with an accident while he is on the run and dies. Now, Ragoo starts following Latha, who makes use of Ragoo’s amnesia to escape from him.
Latha is unaware of the real facts, and goes and meets with Annachi to tell him the details of the person who had made many attempts to kill him. With the identity of his to be nemesis in hand, Annachi plots to kill Ragoo. But Ragoo has other ideas, and he lands in Annachi's shop, only to realize that Annachi has an identical twin. Before he can make a note of it, Latha calls Annachi to tell him to destroy her photograph that Ragoo had to identify her as his friend or hand it over to her. But it was Ragoo picks up the call and notes her address.
Ragoo reaches Latha’s hostel and attempts to accost her. Instead he is trapped, and taken into police custody.
Now comes the dialogue of the movie. The police chief played by Bharath, looks at the tattoos in Ragoo's body and says, “All these numbers are 10 digit, so they must be cell phone numbers. If we call these numbers, we can get his identity.”
One of the phone numbers is that of Annachi, who is forced to pose as his friend. Just then Ragoo’s doctor and lawyers appear and take him home.
Annachi attacks him at his home, but he is unable to kill him, due to the fear of police getting back to him as he has earlier made a statement to police that he was Ragoo’s friend. So he decides to wipe all evidences from Ragoo’s life which would link him to Ragoo. So he destroys all photographs, maps and defaces the tattoos.
Latha suddenly remembers that she had taken the diary from Ragoo’s house. I think she was also suffered a bout of amnesia and forgot about the diary. So she starts reading it.
Now the viewers learn the remaining part of Sanjay’s story.
Savitha also confesses that she is in love with him, and they decide to marry. Even now, Ragoo had not revealed his true identity to her, and as he was about to do that, he gets a call to attend an urgent meeting in 1st sector. Savitha also gets a call to attend a shooting in Mumbai.
The diary ends here. Latha is moved by Ragoo’s story and investigates. She sees a news article on one of the old newspaper she unearthed at the library, which leads her to a school kid as well as a female police office. They tell her the remaining story.
On her way to Mumbai, Savitha rescues a set of girls who were being taken to Mumbai to be sold. Her rescue attempts and daredevilry is praised by the media, but incurs the wrath of Annachi, who lost money due to Savitha’s benevolent attitude.
Ragoo returns and is about to reveal his true identity, only to find that Savita is being attacked by the gang. He tries in vain to save her. Annachi kills Savitha and hits Ragoo on his bald head and Ragoo immediately faints.
After reading the story, Latha is filled with remorse, and what follows now is utter mayhem. I lost track of the movie after it, since it was plain masala stuff. To say it in simple words, with Latha’s help Ragoo tracks the villain and hands him over to Bharath IPS.
The story ends. After which Ragoo regains his memory but the hair never grows. Incidently Latha falls in love for his bald head and they both move to Holland and live happily.
Ragoo now has a different Vyadi. This is his due to the sexual exploits that he was involved in during his 15 minute memory relapses.
