'King') is a 2011 Indian Tamil-language political action thriller film directed by K. V. Anand, and written by him and the duo Subha.

The film stars Jiiva, Ajmal Ameer, Karthika Nair (in her major Tamil debut), and Piaa Bajpai, while Prakash Raj and Kota Srinivasa Rao appear in supporting roles.

The film follows Ashwin (Jiiva), a photojournalist working for Dina Anjal who covers the Tamil Nadu State Election.

The film features music composed by Harris Jayaraj, with cinematography handled by Richard M. Nathan and editing done by Anthony.

Settled in her new job, Renu writes a cover story about a politician Aalavandhan, describing his attempt to marry a minor.

Ashwin later risks his life to capture the pictures of Aalavandhan, who actually engages in child marriage in a temple at midnight.

Meanwhile, Vasanthan Perumal, an engineer and recent graduate, strives hard to enter politics by contesting in the upcoming election.

While photographing the event, Ashwin receives a text message from Saro that states there is a bomb underneath the stage where Vasanthan is speaking.

At the same time, Vasanthan orders the Tamil Nadu Police (T.N.P) to go kill the Naxals at their hideout, and the commandos surround the perimeter of that place.

Ashwin records this confession using his mobile phone camera and sends it to Renu, who plans to publish this story in their newspaper.

Seeing their innocence, Ashwin forces Renu not to reveal the truth about Vasanthan because his party members would get into serious trouble and lose their seats just for supporting him.
