The film begins with ad film-maker Anbarasu (R. Madhavan)- who prefers that his name is mentioned in the abbreviation of A. Aras rather than his full name, arriving at the Bhubaneswar airport in Orissa, India. He is about to board a flight back to Chennai for his own wedding. However, he learns at the airport that his flight is cancelled due to the bad weather in the state where heavy floods and torrential rain due to the wet season have affected air traffic. While waiting for further announcements, Aras watches a television news of a terrorist threat at an airport in Mumbai making him suspicious when he sees a limping man carrying an old sack on his hands. He informs the authorities, who find out that the man only has a cucumber in that bag and nothing else.The man, a physically disabled man named Nallasivam a.k.a Nalla (Kamal Hassan) introduces himself to Aras and both of them get to know each other. However, Aras underestimates Nallasivam, ignoring his advice and friendly acquaintance, resulting in some comical events in the airport itself. Announcements are finally made that the flights would not board on that day and Aras will have to reserve place in nearby hotels to put up the night. Aras realizes that the five star hotel that he was staying in before is now fully booked, leaving him optionless. Nallasivam however helps him find a place in a two star hotel nearby, in which both Nalla and Aras have to share the same room. Aras' resentment of Nalla makes him act selfishly in trying to get rid of Nalla but at every juncture, Nalla does him a favor which leaves Aras with a heavy heart. The next morning, Aras takes a taxi without waking Nalla in order to find his own way to Chennai. However, Aras realizes that the floods have blocked most of the roads and even the train station is covered by high levels of water. He gets mugged by a thief in the station who offers to help Ars with his luggages, and loses all his money. Nalla however comes to the station and helps Aras retain the wallet, sans the money. It is then revealed that Nalla is a trade unionist and is travelling with a cheque worth Rs. 30 lakh to be delivered to some people after fighting a court cases for some union workers. The comical and misunderstanding events continue as the pair make it to a different train station. There, Nalla decides to tell the story of his own past, but a tired Aras falls asleep and walks away as he is about to begin.The film then flashes to few years back when a perfectly good looking Nalla performs in street theatres protesting against the industrialisation process which is marginalizing labor force. He often gets into trouble due to this. Nalla is also a painter, and a very talented one at that. He is fighting mainly against the town's biggest business tycoon, the manipulative Kandasamy Padayachi (Nassar), whom he satirically imitates during many of his shows. However, an interesting turn of events sees Nalla and Kandasamy's own daughter Bala (Kiran Rathod) fall in love with each other. Realizing Kandasamy's power would be too much to bear if they want to get together, Nalla and Bala decide to elope, but while Nalla is on a bus on his way to meet Bala, the bus meets with a horrible accident at a hillside which leaves Nalla badly injured, which subsequently leads him to be paralyzed. Bala is told by her father that Nalla is dead, while Nalla suffers from inferiority complex on his new, paralyzed look and starts wondering about doing social work and still fighting for union causes. Nalla is also shown as a communist believer.The film returns to present times, as Aras and Nalla board the train for which they have been waiting, but as the train arrives, they get into an argument about communism, Karl Marx, and so on. Nalla accuses Aras as an agent for Western and rich manipulation, while Aras defends himself and criticises communism as a whole, referring that the Soviet Union doesn't exist anymore. Nalla argues that the idea of communism wouldn't die. The argument turns heated and sensitive, causing a short-tempered Aras to punch Nalla.The film portrays about the communal issues going on and how each one defending from the viewpoint.
