Ravi lives in Tuticorin. He aspires to become a policeman like his idol, Police Officer Devaraj IPS. After completing his 12th standard, he joins a college in Chennai, and also earns a living by driving an auto rickshaw. During the course, he meets Suseela in and falls in love with her instantly. With the help of her grandmother, he succeeds in winning Suseela's heart.
Chella is a criminal who wants any girl he desires. He meets Uma in a public place and insults her by removing her saree. Ravi comes to her defense and defeats Chella, hospitalizing him. His troubles start as Chella's father, a criminal don named Vedanayakam, with the help of a corrupt police officer Kattabomman, begins to create havoc in Ravi's life. Ravi himself is thrown in jail on a false case and is expelled from college. Only Suseela is willing to actively help him.
As Ravi turns to his mentor Devaraj for help, he shockingly learns that Devaraj's family has died at the hands of Vedanayakam and that Devaraj himself has been blinded by Vedanayagam and is helpless. It is at this stage that Ravi takes up a new persona called "Police" Ravi to clean up the illegal activities of Vedanayagam.
Will Ravi be able to instill hope in the public and do what Devaraj was unable to do?
