Shiva is a CB-CID officer who attempts to foil terrorist John Chinnappa. He is simultaneously attempting to mend relations with his father's estranged first wife and his half-brother Narain. However, complications ensue.
Major John Chinnappa is a scientist who created tablets by operating on human guinea pigs. His ploys have always been controversial but inconclusive due to the lack of witnesses. However, an ex-gang member, General Ram Prasad, became a police approver and is on the verge of revealing John's ploys to the police. However, he is on the run to avoid charges. The case falls to Commissioner Karthikeyan, Shiva's father, who assigns his son to go and help solve the mission.
Karthik tells Shiva to attend college in Tamil Nadu (St. John's College, Ooty) to protect Ram Prasad's daughter Pooja from meeting her father. Shiva pleads that he has never undertaken this type of mission before and knows little about the current generation. The general points out that, by a strange coincidence, Pooja attends school in the same town where Ram Prasad is hiding. Shiva can both protect Pooja and search for Ram Prasad. Shiva goes undercover as a student returning to college after many years away from taking care of the family business. He is much older than the other students, who at first make fun of him because of his lack of newer styles. He also has to deal with the many goofy teachers, as well as Albert Aadiyapatham, the idiotic and forgetful college principal.
Soon, Shiva finds Narain, who is later revealed to be his brother. Pooja is Narain's best friend, and she is secretly jealous that other girls can get his attention, but she cannot. Shiva saves Pooja from John's men, who kidnap her, while Narain and others think that it is a prank. He later becomes a sensation among the students and teachers. He befriends Narain and Pooja. Soon, he falls in love with the chemistry teacher Mallika after being attracted by her beauty and in a bid to convince other students that he is one of them. During his regular jogging sessions, Shiva spots Ram Prasad and chases him until he escapes with the help of a helmet-clad bike rider, who is later revealed to be Narain. Pooja discovers that Narain has been helping her father and feels cheated by him.
Narain apologizes to Pooja many times, but she refuses to talk to him. Irked by this, Narain drinks and explains his actions when John's men come again to kidnap Pooja. They beat up Narain, but Shiva comes to their rescue. Narain and Pooja patch up after the fight. Shiva takes Narain to his home, where he learns that Narain is his brother and meets his mother Kasthuri. The flashback sequences describe Shiva's orphaned childhood and explain why his mother and father live separately.
The next day, when Pooja introduces Ram Prasad to Shiva, Shiva arrests him, much to Pooja and Narain's disappointment. Then everyone in the college, including Mallika, learns that Shiva is a policeman. Shiva then drives Ram Prasad straight to John's hiding place, avoiding the traps that he had set. A fight ensues between Shiva and John's men, where John is finally killed.
In the final scenes, Mallika is shown with Shiva's parents and brother, while Shiva has gone to Afghanistan for another mission.
