Twin brothers with contrasting paths. Kodi is a passionate Democratic party organizer driven by his father's protest against toxic factory waste. Anbu is an apolitical engineering professor who falls for Malathi and later uncovers the mercury scandal. Kodi is framed and killed by Rudra during the campaign, while Anbu survives, confronts the culprits, and wins the by-election, adopting his brother's mannerisms.
