Arul Kumaran, a factory worker separated from his family of goldsmiths in Coimbatore, gets into a verbal fight with the corrupt MLA Gajapathy, which results in Arul killing Gajapathy. Arul surrenders to the cops, but is later released from prison. Sethupathy, Gajapathy's brother and a political kingmaker, wants to exact revenge on Arul for Gajapathy's death. A cat and mouse game ensues in which Arul takes responsibility of cleaning anti social elements and also becomes the kingmaker of Coimbatore.
