The plot continues two years after the incidents in Naan. Karthik, alias Mohammed Salim, a bright student from Ramanathapuram, is an honest doctor at a private hospital in Chennai. Now a good Samaritan, Salim often goes out of his way to help needy patients who visit him. His skill and nature earn him the wrath and jealousy of his colleagues. One day, he learns that someone is stalking him and finds it is his suitor Nisha. Salim goes directly to Nisha and gives her his personal diary so she can learn more about him. This response from Salim impresses Nisha so much that she falls in love with him. As their relationship progresses, Nisha learns that Salim has dedicated himself to his work, so much so that he fails to take care of her and spend time with her, thus creating a rift between them. To reconcile with Nisha, Salim plans to spend a whole day with her. They go to a movie theatre, and some goons tease Nisha, but Salim chooses to take Nisha and leave the place. Nisha gets offended and starts to ignore Salim and his phone calls.
Meanwhile, the hospital's managing director warns Salim to stop refusing fees from poor patients as it affects the hospital's income. A few days later, Salim reconciles with Nisha, and they renew their relationship. Nisha invites Salim to a party, and he accepts. But, on the way, Salim sees a young girl, a gang rape victim, who is hurt and bleeding on the road. He takes her to the hospital and misses the party. Nisha loses her temper and breaks up with him.
The next day, Salim finds that the girl was discharged from the hospital by the managing director as she is poor and unable to pay for her treatment. The same evening, Salim gets an invitation to a party from his hospital. Salim learns that the managing director has had enough of his charity and generosity at the hospital's cost. Salim also learns that he is being sacked, and it is his own farewell party. He is also insulted by the managing director for not using his talent and reputation to earn money. Salim storms out of the party in rage. On the way, he gets into a scuffle with a police officer and hits him, ending up in the police station. But he escapes with the police officer's pistol and goes straight to a hotel. There, he finds four men trying to rape the hotel's singer. He beats them up and helps the girl leave the place. Saying that they have to learn their lesson, Salim takes them hostage inside the room. One of the men, Guru, is the son of Home Minister Thavapunniyam, so the police, led by officer Chezhian, are pressured to take immediate action.
The police discover Salim's identity and raid his home, where they find his wedding card and learn about Nisha. They take her into custody and to the hotel, where she meets Chezhian and explains Salim's character and that he is not a terrorist to take hostages. The police plan to use Nisha as bait and capture Salim, but they fail to do so when Salim demands the presence of Thavapunniyam at the hotel. Meanwhile, a police sniper shoots at Salim but misses, and Salim throws one of the men out of a window. He tells Chezhian to take him seriously to avoid more disastrous results. It is later revealed that the four men had raped the girl whom Salim had found on the roadside. After her discharge from the hospital, they killed the victim and her mother and disposed of their remains in a sewage drain.
Salim realises he will not be left alive by Thavapunniyam once he lets go of the hostages. So he demands a car for him to leave and tells the police not to follow him. This time, Thavapunniyam arranges a car fitted with a bomb and a remote detonator. Salim continues to hold Guru hostage and gets into the latter's car instead. Later, Thavapunniyam receives a call from Guru telling him that Salim left him on the East Coast Road and escaped. Thavapunniyam orders his men to bring Guru back and kill Salim, who has driven away and made it look like an automobile accident. The men chase the car with trucks and crash into it, only to find Guru inside.
