Pokiri

The hero (Vijay), a young IPS officer, acts as an undercover cop to weed out the anti-socials who are ruling the roost. A gang controlled by underworld don, Prakash Raj, operates with impunity. Vijay makes "Fight evil with evil" as his credo and is out to eliminate the gang outside the pale of law with indomitable courage and ingenuity.

Asin works as an instructor at an aerobic centre run by Nasser, a retired circle inspector, who is proud of being a sincere and straightforward member of the police force. The girl falls in love with Vijay.
