Narasimham (Suriya) goes undercover with the intention of tracking the illegal activities of some sea based gangs in Kakinada. He manages to convince everyone, including his parents, that he is no longer a cop and joins a school as an NCC officer. He starts a covert surveillance program on the activities of dreaded smuggler Bhai (Mukesh Rishi) and uncovers the secrets of their operation.

Meanwhile, Sathya (Hansika) is a student in the same school and she falls in love with Narasimham. She also happens to be the niece of Thyagaraju (Rahman), a rich businessman who heads the Golden Shipping company. Thyagaraju and Bhai come across as enemies.

Once Narasimham has the necessary evidence on hand to round up the gang, he comes out of his cover identity and assumes charge as a DSP. He starts rounding up the gang members and comes to know about the ruthless international drug kingpin Danny (African Actor). Narasimham also discovers some truths about Bhai and Thyagaraju.

Will Narasimham be able to stop Danny and his drug operation? What does he lose in the process? That forms the rest of the story.
