Output: Aegans story is based around Shiva Ajith Kumar, a CBCID officer, and his efforts to foil the terrorist John Chinnappa Suman. Shiva is simultaneously attempting to mend relations with his fathers estranged first wife and his halfbrother Narain Navdeep. Complications ensue. Major John Chinnappa is a scientist who had created tablets by operating on human guinea pigs. His ploys have always been controversial but inconclusive due to the lack of witnesses. However, an exgang member, General Ram Prasad Devan, became a police approver and is on the verge of revealing Chinnappas ploys to the police. However, he is on the run to avoid charges. The case falls to Commissioner Karthikeyan Nassar, Shivas father, who assigns his son to go and help solve the mission. Karthik tells Shiva to attend college in Tamil Nadu – St. Johns College, Ooty – to protect Ram Prasads daughter, Pooja Piaa Bajpai, from meeting with her father. Shiva pleads that he has never undertaken this type of a mission before and doesnt know much 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 protect Pooja and look for Ram Prasad at the same time. Shiva goes undercover as a student returning to college after many years away 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 newgeneration styles. He also has to deal with the many goofy teachers as well the idiotic forgetful principal of the college, Albert Jayaram. He finds Narain, who is later revealed to be Shivas brother. Pooja is Narains best friend and he is secretly jealous that other girls can get his attention but she cant. Shiva saves Pooja from John Chinnapas men, who kidnap her while Narain and others think its a prank. He later becomes a sensation among the students and teachers. He befriends Narain and Pooja and falls in love with the chemistry teacher, Mallika Nayanthara, 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 till he escapes with the help of an helmetclad bike rider who is later revealed to be Narain. Pooja comes to know that Narain has been helping her father and feels cheated by him. Narain tries to apologise to Pooja many times, but she refuses to talk to him. Irked by this, Narain drinks and explains his actions when Johns men come again to kidnap Pooja. They beat up Narain, but Shiva comes to their rescue. Narain and Pooja patch up after the fight sequences. Shiva takes Narain to his home where he learns that Narain is his brother and meets his mother. The flashback sequences describe Shivas childhood he is an orphan and explain why his mother and father live separately. The next day when Pooja introduces Ram Prasad to Shiva, Shiva arrests him – much to the disappointment of Pooja and Narain. Then everyone in the college including Mallika learns that Shiva is a policeman. Shiva then drives Ram Prasad straight to John Chinnapas hiding place, avoiding the traps that he had set. A fight ensues between Shiva and John Chinnappas men in which John is finally killed. In the final scenes Mallika is shown with Shivas parents and brother while he has gone to Afghanistan as part of another mission.
